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.
