Clevite 77® cam bearings are precision bored
to eliminate the need for machining after installation. This
exclusive bearing design features a steel backing for support,
a cast-copper lead alloy center for strength and durability,
nickel dam for chemical stability, and an electroplated white
metal babbitt overlay for slipperiness, conformability and
embedability. The intermediate cast-copper lead layer creates
and interlocked columnar structure capable of withstanding
much heavier pulsating loads than any other bearing design.
