Bearing Crush Automotive Terminology Explained

Bearing Crush (bearing nip) A means of ensuring that a plain bearing is a secure interference-fit in its housing. The term is applied particularly to big-end and main bearings. The shells in both types stand slightly proud of their housings under light connecting pressure, but when the cap is fully tightened the proud portion is nipped back ...

Measurement of bearing clearance - Turbomachinery ...

Nov 27, 2016  Bearing clearance is one of the most important parameters in the operation of a bearing. Therefore, it is important to determine the installed clearance along with the bore contour and concentricity to the outside fit diameter. The final bearing clearance is influenced by the contour of the housing into which it is installed, and also by the amount of interference or crush between the bearing ...
