HDP engine bearings are made of a sintered tri-metal with a base alloy of copper/lead and tin with a nickel dam and Babbitt top layer. This advanced technology alloy has a higher load carrying capacity than aluminum or other copper/lead alloy. As a result of this, our rod and main bearings 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.
