  • Crankshaft Bearing - an overview | ScienceDirect Topics

    The bearing, known as a thin wall bearing, consists of a thin steel shell, typically 2 mm thick, lined with one or more layers of bearing material with a total thickness of about 300 μm. The shell is split into two to allow assembly, and is formed from low- or medium-carbon steel strip to standard dimensions for interchangeability.
