These Tri-Metal 77 engine bearings combine the strength of a copper-lead alloy layer with steel backing and an electroplated babbitt metal. The steel backing provides strength and durability; the babbitt overlay provides the critical surface characteristics of slipperiness and conformability. This ideal design has properties not even found in many original equipment bearings. Clevite offers main bearings, rod bearings and cam bearings in this series.
P Series Bearings - Traditional Clevite 77 Tri-Metal Bearings have high crush qualities for maximum bearing retention, high eccentricity to account for bore distortion and and reduced overlay thickness to prevent fatigue.
H Series Bearings - Drag Race Engine Builders prefer their lack of flash plating, medium levels of eccentricity, enlarged chamfers for additional crankshaft fillet clearance and high crush.
