Cummins Camshaft Bearings

Cummins Camshaft Bearings 

When speaking about engine bearings, most commonly, we focus on main and connecting rod bearings and the roles they play in crankshaft operation. Camshaft bearings are less loaded and generally have fewer problems. Therefore, innovative bearing materials and new designs are mostly focused on crankshaft bearings, where probability of failure is greater.

However, camshaft bearings are also hydrodynamic bearings.They suffer from the same operational conditions as do crankshaft bearings: overloading, oil starvation, too thin

minimum oil film, misalignment, and contaminated oil. The possible failures are also similar: material fatigue, excessive wear, seizure, and corrosion.
