What effect does the clearance of the slewing bearing have on the use？
Clearance is an important technical parameter of slewing bearing , which directly affects the technical performance of the bearing's load distribution, vibration, noise, friction, temperature rise, service life and mechanical operation accuracy. Too large clearance will cause the bearing internal capacity area to decrease, the stress on the contact surface will increase, the rotation accuracy will decrease, the vibration and noise will increase. As a result, the service life is shortened and the clearance is too small, the negative clearance (interference) may occur in actual operation, rotation jamming will be inflexible, resulting in increased friction and heating, increased temperature rise, which will make the effective clearance smaller or larger, this vicious circle will cause the bearing to lock and cannot rotate. The bearing's clearance value is artificially specified by the designer and a certain range is divided according to the size of the slewing bearing, which is u
