Clevite rod bearings come in a wide variety of styles for a wide range of vehicles, from mild to wild.
They are made to meet OEM standards for strength and durability and will help give your engine extra life.
Their quality construction and superior materials protect vital parts from the harmful effects of friction.
There are thousands of applications, with subtle differences that cover numerous variations and uses, so be sure to find the bearings you need for your engine.
P-Series Bearings should not be confused with standard passenger car and light truck parts for the same applications that also have a P suffix letter.
These high-performance parts have unique part numbers different from standard parts for the same application.
P-Series parts are the oldest series of Clevite high-performance bearings.
Rod bearings in this series typically have the highest amount of eccentricity.
Most rod bearings are available with or without dowel holes for use in aluminum rods.
Most P-Series main assemblies are fully grooved to maximize oil flow to the rod bearings.
Both rods and web have high crush for maximum retention and reduced overlap thickness to prevent overlap fatigue, sometimes referred to as hen tracking.
Rod bearings use a hardened steel back for strength and fret resistance.
Extra-clearance rod bearings are available for 0.001 extra clearance and select fit.
Use P-Series rods where extremely high RPMs cause severe approach of the rod bore, typically indicated by the nearly complete parting line to shaft contact with bearings that have less runout.
Use P-Series web where greater eccentricity is desired, with close contact patterns and to provide increased lubrication of the surround rings.
Rod bearing oil starvation is typically indicated by polishing and staining of the bearing surface, possibly accompanied by discoloration concentrated predominantly on the axis.
