  • What is the Preload of Crossed Roller Bearings? -

    2020-3-16 · What is the preload of crossed roller bearings? Generally, rolling bearings have a certain clearance under working conditions. However, in order to achieve a specific purpose, during the cross roller bearing's assembly, apply a certain internal load through adjustment of the clearance to achieve negative clearance.This method is called preload.
