Engine Bearings
Bearings made from copper/lead and nickel/nickel resin have a silicon dam and a Babbitt top layer. They are made using a sintered tri-metal with a base alloy of copper, lead, and tin. Aluminum or copper/lead alloys are not as load-bearing as F780. The material F780 provides greater life in normal operation as well as significantly improved fatigue resistance under extreme operating conditions. Additionally, we offer engine bearings made of aluminum, alloys, and other materials
