Blended Edge Main Bearings

424 Downloads

The blended edge (BE) design was introduced on thin shell white metal main bearings to better cope with crankshaft inclinations and thereby increase the resistance towards edge fatigue failures. The blended edge design is the corresponding item to the thick shell flex-edge design for MC engines.

Occasionally, bearings fail without any clear root cause, but for example indications of small imperfections of the journal geometry could be found. In such cases, a BE bearing could be the solution, depending on the actual failure type.
