Scope
This standard provides recommended parameters for the working environment of crankshaft bearings in automotive engines. It explains that, under the current processing equipment, most engine manufacturers can achieve various dimensions and states of the crankshaft bearings' working environment to meet the requirements of the crankshaft bearings' working environment, and such a working environment will not cause bearing problems.
Some of the recommended parameters in this standard cannot fully meet the requirements of certain applications. In these applications, design specifications require more precise and high-quality parts.
