P Series Conrod Bearing Set STD
Suit SB Chrysler 273, 318, 340 & 360
P-Series Bearings
These are not to be confused with the standard passenger car and light truck parts for the same retention applications which also have a "P" suffix letter. These high performance parts have unique core part numbers different from the standard parts for the same application. P series parts are the oldest series of Clevite high performance bearings. The rod bearings in this series typically have the greatest amount of eccentricity. Most rod bearings are available either with or without dowel holes for use in aluminium rods. Most P series main sets are full grooved to maximise oil flow to the rod bearings. Both rods and mains have high crush for maximum retention, and a reduced overlay thickness to prevent overlay fatigue, sometimes referred to as hen tracking.
Rod bearings use a hardened steel back for added strength and resistance to fretting. extra clearance rod bearings are available for .001" additional clearance and select fitting. Use the P series rods where extremely high RPM's cause severe rod bore close-in. This is typically indicated by nearly full parting line to parting line shaft contact with bearings having less eccentricity. Use P series mains where higher eccentricity is desired to narrow bearing contact patterns and to provide increased oiling to rod bearings. Rod bearing oil starvation is typically indicated by polishing and smearing of the bearing surface, possibly accompanied by discolouration predominantly concentrated at the axial center of the bearings.

H-Series Bearings
These bearings are identified by a letter H in the part number suffix. Part numbering is based on the same core number as the standard passenger car parts for the same application. These bearings were developed primarily for use in NASCAR type racing, but are suitable for all types of competition engines.
H series bearings have a medium level of eccentricity, high crush, and rod bearings have a hardened steel back and thin overlay. These bearings also have enlarged chamfers for greater crankshaft fillet clearance and are made without flash plating for better seating. Bearings with .001" extra clearance are available for standard size shafts and carry the suffix HX" (X = extra clearance). Rod bearings are available with or without dowel holes (HD = with, H = without), main bearings are available with standard 180 degrees upper half grooving and with full 360 degrees grooving (H = 180 degrees, HG 360 degrees). Use H series bearings with crankshafts that have oversize fillets and where engines run in the medium to high RPM range. H series bearings should be used if contact patterns obtained with P series parts are too narrow. Contact patterns should ideally cover 2/3 to 3/4 of the bearing surface. See accompanying contact pattern diagrams. If you aren't sure which type of performance bearing to start with, the H series bearing will be your best choice.
Please note: Some "H" series bearings will no longer be available with enlarged chamfers. Instead, the bearings will be narrowed in place of the enlarged chamfer to provide greater crankshaft fillet clearance. The new narrowed bearings will be available with a "HN" suffix and will be replacing the standard "H" suffix part number.

TriArmour Series Bearings
 
The exclusive Clevite TriArmor engine bearings feature the industry's only moly/graphite treatment. This sophisticated blend, in a low friction PTFe polymer base, offers extraordinary protection and lubricity. enhanced wear characteristics increase bearing life in race engines and high performance street engines.
 
Now, high performance engine builders can enjoy the strength and durability of the legendary Clevite TriMetal bearing construction coupled with the latest in coating technology - right out of the box.
 
The line of Clevite TriArmor rod and main bearings include popular Ford, GM and Chrysler models as well as popular Sport Compact applications.
 
Exclusive Moly/Graphite Treatment
 
For years, engine builders have experimented with coating engine bearings for race engines and high performance street engines, with varying degrees of success. Now, Mahle Clevite engineers, after extensive research and development, have devised TriArmor, a proprietary blend of molybdenum disulfide (MoS2) and graphite all carried in an inert polymer substrate.
 
Central to this breakthrough is the exclusive use of graphite and unique application and low temperature cure processes. These processes provide extremely uniform thickness coupled with unparalleled adhesion, all while protecting the metallurgical integrity of the bearing during the coating procedure.
 
The result? A thin protective coating that offers:
 
Reduced friction and drag, resulting in increased horsepower
Protection during start-up
embedability to resist damage from debris
Ability to withstand extreme temperatures and pressures
Conformability for distressed or imperfect surfaces
extraordinary strength and durability
TriArmor Features &Benefits
 
In developing TriArmor materials and processing, MAHLE Clevite engineers relied on the science of Tribology, the study of design, friction, wear, and lubrication characteristics of interacting surfaces. With our existing body of knowledge based on decades of producing bearings for street and track, this model enabled us to produce the most advanced and efficient coating material possible. The PTFE carrier material gives good low load start-up protection. The moly serves as a high pressure, high load dry film anti-wear agent. Graphite provides additional protection across a broad range of temperatures, especially when oil flow is marginal and is especially slippery with an oil film.
 
Exclusive Clevite TriArmor Features:
 
Moly/graphite compound
Coverage for Ford, GM and Chrysler as well as popular Sport Compact Applications
Parting lines not coated
Legendary Clevite quality

The rod bearings in this series typically have the greatest amount of eccentricity. Most rod bearings are available either with or without dowel holes for use in aluminium rods. Most P series main sets are full grooved to maximise oil flow to the rod bearings. Both rods and mains have high crush for maximum retention, and a reduced overlay thickness to prevent overlay fatigue, sometimes referred to as hen tracking.
Rod bearings use a hardened steel back for added strength and resistance to fretting. extra clearance rod bearings are available for .001" additional clearance and select fitting. Use the P series rods where extremely high RPM's cause severe rod bore close-in. This is typically indicated by nearly full parting line to parting line shaft contact with bearings having less eccentricity. Use P series mains where higher eccentricity is desired to narrow bearing contact patterns and to provide increased oiling to rod bearings. Rod bearing oil starvation is typically indicated by polishing and smearing of the bearing surface, possibly accompanied by discolouration predominantly concentrated at the axial center of the bearings.

These bearings are identified by a letter H in the part number suffix. Part numbering is based on the same core number as the standard passenger car parts for the same application. These bearings were developed primarily for use in NASCAR type racing, but are suitable for all types of competition engines.
H series bearings have a medium level of eccentricity, high crush, and rod bearings have a hardened steel back and thin overlay. These bearings also have enlarged chamfers for greater crankshaft fillet clearance and are made without flash plating for better seating. Bearings with .001" extra clearance are available for standard size shafts and carry the suffix HX" (X = extra clearance). Rod bearings are available with or without dowel holes (HD = with, H = without), main bearings are available with standard 180 degrees upper half grooving and with 360 degrees grooving (H = 180 degrees, HG 360 degrees). Use H series bearings with crankshafts that have oversize fillets and where engines run in the medium to high RPM range. H series bearings should be used if contact patterns obtained with P series parts are too narrow. Contact patterns should ideally cover 2/3 to 3/4 of the bearing surface. See accompanying contact pattern diagrams. If you aren't sure which type of performance bearing to start with, the H series bearing will be your best choice.
Please note: Some "H" series bearings will no longer be available with enlarged chamfers. Instead, the bearings will be narrowed in place of the enlarged chamfer to provide greater crankshaft fillet clearance. The new narrowed bearings will be available with a "HN" suffix and will be replacing the standard "H" suffix part number

Please note: Some "H" series bearings will no longer be available with enlarged chamfers. Instead, the bearings will be narrowed in place of the enlarged chamfer to provide greater crankshaft fillet clearance. The new narrowed bearings will be available with a "HN" suffix and will be replacing the standard "H" suffix part number.

These bearings are identified by a letter H in the part number suffix. Part numbering is based on the same core number as the standard passenger car parts for the same application. These bearings were developed primarily for use in NASCAR type racing, but are suitable for all types of competition engines.
 
H series bearings have a medium level of eccentricity, high crush, and rod bearings have a hardened steel back and thin overlay. These bearings also have enlarged chamfers for greater crankshaft fillet clearance and are made without flash plating for better seating. Bearings with .001" extra clearance are available for standard size shafts and carry the suffix HX" (X = extra clearance). Rod bearings are available with or without dowel holes (HD = with, H = without), main bearings are available with standard 180 degrees upper half grooving and with full 360 degrees grooving (H = 180 degrees, HG 360 degrees). Use H series bearings with crankshafts that have oversize fillets and where engines run in the medium to high RPM range. H series bearings should be used if contact patterns obtained with P series parts are too narrow. Contact patterns should ideally cover 2/3 to 3/4 of the bearing surface.

P-Series Bearings
 
These are not to be confused with the standard passenger car and light truck parts for the same retention applications which also have a "P" suffix letter. These high performance parts have unique core part numbers different from the standard parts for the same application. P series parts are the oldest series of Clevite high performance bearings. The rod bearings in this series typically have the greatest amount of eccentricity. Most rod bearings are available either with or without dowel holes for use in aluminium rods. Most P series main sets are full grooved to maximise oil flow to the rod bearings. Both rods and mains have high crush for maximum retention, and a reduced overlay thickness to prevent overlay fatigue, sometimes referred to as hen tracking.
 
Rod bearings use a hardened steel back for added strength and resistance to fretting. extra clearance rod bearings are available for .001" additional clearance and select fitting. Use the P series rods where extremely high RPM's cause severe rod bore close-in. This is typically indicated by nearly full parting line to parting line shaft contact with bearings having less eccentricity. Use P series mains where higher eccentricity is desired to narrow bearing contact patterns and to provide increased oiling to rod bearings. Rod bearing oil starvation is typically indicated by polishing and smearing of the bearing surface, possibly accompanied by discolouration predominantly concentrated at the axial center of the bearings.

Heavy Duty Cam Bearings
 
B-1Steel back tin or lead base conventional Babbitt (nominal .020" thickness
 
In the last decade or so engine development has increased dramatically. Each time an existing engine is revised or a new engine is developed, it pushes the limits of what its predecessor could produce both in horsepower and torque as well as fuel efficiency. With these gains, comes an increased load on the internal parts of these engines. One of these parts that are continually asked to perform under greater and greater pressures is the cam bearing. In engine configurations such as V6's and high RPM 4 cylinders, the cam bearing is a vital link along the path of the engines oiling system. If a cam bearing wears out prematurely the engine loses some of its oil pressure, which we all know can lead to premature engine failure. Other problems, which can be caused by premature cam bearing wear, are excessive cam lobe runout, improper timing, and generally poor running conditions. This is where strength and durability become key issues. This is why, in most applications, the O.E. manufacturers have turned to higher performing cam bearing materials. Traditional Babbitt can only withstand up to 1800 psi. Clevite's AL-3 material can withstand up to 5000 psi. Quite a difference. When trying to adapt Babbitt to an application that requires a more durable material, extra oil grooves are needed on the outside diameter of the bearing itself to help get oil to the rest of the engine. This only addresses the oil starvation symptom inherent to the real problem of premature wear. All of the other symptoms that were listed above still occur with the right material for the job, such as Clevite's AL-3, these extra oil grooves aren't needed at all. In fact this gives more bearing contact area to the block to help in transferring heat away from these parts and prolonging bearing and engine life. Remember, when strength and durability is part of the question, Clevite is the answer.
 
On certain modified performance applications Clevite also offers a TriMetal cam bearing material (TM-1) that provides even greater strength and durability. These cam bearings are able to withstand loads in excess of 8,000 psi, while providing surface characteristics that are very forgiving and conformable.

This is where strength and durability become key issues. This is why, in most applications, the O.E. manufacturers have turned to higher performing cam bearing materials. Traditional Babbitt can only withstand up to 1800 psi. Clevite's AL-3 material can withstand up to 5000 psi. Quite a difference. When trying to adapt Babbitt to an application that requires a more durable material, extra oil grooves are needed on the outside diameter of the bearing itself to help get oil to the rest of the engine. This only addresses the oil starvation symptom inherent to the real problem of premature wear. All of the other symptoms that were listed above still occur with the right material for the job, such as Clevite's AL-3, these extra oil grooves aren't needed at all. In fact this gives more bearing contact area to the block to help in transferring heat away from these parts and prolonging bearing and engine life. Remember, when strength and durability is part of the question, Clevite is the answer.
 
On certain modified performance applications Clevite also offers a TriMetal cam bearing material (TM-1) that provides even greater strength and durability. These cam bearings are able to withstand loads in excess of 8,000 psi, while providing surface characteristics that are very forgiving and conformable.

In the last decade or so engine development has increased dramatically. Each time an existing engine is revised or a new engine is developed, it pushes the limits of what its predecessor could produce both in horsepower and torque as well as fuel efficiency. With these gains, comes an increased load on the internal parts of these engines. One of these parts that are continually asked to perform under greater and greater pressures is the cam bearing. In engine configurations such as V6's and high RPM 4 cylinders, the cam bearing is a vital link along the path of the engines oiling system. If a cam bearing wears out prematurely the engine loses some of its oil pressure, which we all know can lead to premature engine failure. Other problems, which can be caused by premature cam bearing wear, are excessive cam lobe runout, improper timing, and generally poor running conditions.

These are not to be confused with the standard passenger car and light truck parts for the same retention applications which also have a "P" suffix letter. These high performance parts have unique core part numbers different from the standard parts for the same application. P series parts are the oldest series of Clevite high performance bearings. The rod bearings in this series typically have the greatest amount of eccentricity. Most rod bearings are available either with or without dowel holes for use in aluminium rods. Most P series main sets are full grooved to maximise oil flow to the rod bearings. Both rods and mains have high crush for maximum retention, and a reduced overlay thickness to prevent overlay fatigue, sometimes referred to as hen tracking.
Rod bearings use a hardened steel back for added strength and resistance to fretting. extra clearance rod bearings are available for .001" additional clearance and select fitting. Use the P series rods where extremely high RPM's cause severe rod bore close-in. This is typically indicated by nearly full parting line to parting line shaft contact with bearings having less eccentricity. Use P series mains where higher eccentricity is desired to narrow bearing contact patterns and to provide increased oiling to rod bearings. Rod bearing oil starvation is typically indicated by polishing and smearing of the bearing surface, possibly accompanied by discolouration predominantly concentrated at the axial center of the bearings.

TriArmour Series Bearings

The exclusive Clevite TriArmor engine bearings feature the industry's only moly/graphite treatment. This sophisticated blend, in a low friction PTFe polymer base, offers extraordinary protection and lubricity. enhanced wear characteristics increase bearing life in race engines and high performance street engines.

Now, high performance engine builders can enjoy the strength and durability of the legendary Clevite TriMetal bearing construction coupled with the latest in coating technology - right out of the box.

The line of Clevite TriArmor rod and main bearings include popular Ford, GM and Chrysler models as well as popular Sport Compact applications.

Exclusive Moly/Graphite Treatment

For years, engine builders have experimented with coating engine bearings for race engines and high performance street engines, with varying degrees of success. Now, Mahle Clevite engineers, after extensive research and development, have devised TriArmor, a proprietary blend of molybdenum disulfide (MoS2) and graphite all carried in an inert polymer substrate.

Central to this breakthrough is the exclusive use of graphite and unique application and low temperature cure processes. These processes provide extremely uniform thickness coupled with unparalleled adhesion, all while protecting the metallurgical integrity of the bearing during the coating procedure.

The result? A thin protective coating that offers:

• Reduced friction and drag, resulting in increased horsepower
• Protection during start-up
• embedability to resist damage from debris
• Ability to withstand extreme temperatures and pressures
• Conformability for distressed or imperfect surfaces
• extraordinary strength and durability

TriArmor Features & Benefits

In developing TriArmor materials and processing, MAHLE Clevite engineers relied on the science of Tribology, the study of design, friction, wear, and lubrication characteristics of interacting surfaces. With our existing body of knowledge based on decades of producing bearings for street and track, this model enabled us to produce the most advanced and efficient coating material possible. The PTFE carrier material gives good low load start-up protection. The moly serves as a high pressure, high load dry film anti-wear agent. Graphite provides additional protection across a broad range of temperatures, especially when oil flow is marginal and is especially slippery with an oil film.

Exclusive Clevite TriArmor Features:

• Moly/graphite compound
• Coverage for Ford, GM and Chrysler as well as popular Sport Compact Applications
• Parting lines not coated
• Legendary Clevite quality

H-Series Bearings

These bearings are identified by a letter H in the part number suffix. Part numbering is based on the same core number as the standard passenger car parts for the same application. These bearings were developed primarily for use in NASCAR type racing, but are suitable for all types of competition engines.

H series bearings have a medium level of eccentricity, high crush, and rod bearings have a hardened steel back and thin overlay. These bearings also have enlarged chamfers for greater crankshaft fillet clearance and are made without flash plating for better seating. Bearings with .001" extra clearance are available for standard size shafts and carry the suffix HX" (X = extra clearance). Rod bearings are available with or without dowel holes (HD = with, H = without), main bearings are available with standard 180 degrees upper half grooving and with full 360 degrees grooving (H = 180 degrees, HG 360 degrees). Use H series bearings with crankshafts that have oversize fillets and where engines run in the medium to high RPM range. H series bearings should be used if contact patterns obtained with P series parts are too narrow. Contact patterns should ideally cover 2/3 to 3/4 of the bearing surface. See accompanying contact pattern diagrams. If you aren't sure which type of performance bearing to start with, the H series bearing will be your best choice.

Please note: Some "H" series bearings will no longer be available with enlarged chamfers. Instead, the bearings will be narrowed in place of the enlarged chamfer to provide greater crankshaft fillet clearance. The new narrowed bearings will be available with a "HN" suffix and will be replacing the standard "H" suffix part number.
