CTP Engine Bearings
CTP Copper/Lead bearings are made of a sintered trimetal with a base alloy copper, lead and tin with a nickel dam and Babbitt top layer. The F780 alloy has a higher load carrying capacity than aluminum or other copper/lead alloy. As a result of this advance technology material, F780 will provide longer life in normal operation and significantly improved fatigue resistance under extreme operating conditions. We also have available engine bearings made of aluminum, alloy, and other materials.

The sizes shown on this reference chart are given in inches. There is a gradual change in the industry to the use of millimeters instead of inches for size identification marks on engine main and connecting rod bearings. The chart shows a comparison of millimeter to inch dimensions for different sizes of bearings.
