Deep Groove Ball Bearing skf bearings

Deep Groove Ball Bearing skf bearings tolerance

Standard deep groove ball bearings have ordinary grades, all of which are in compliance with GB/T 307.3-1996.

Deep Groove Ball Bearing skf bearings clearance

The radial clearance of bearings is divided into original clearance, installation clearance and working clearance. Usually, the original radial clearance of the bearing is greater than the clearance when the bearing is operating. Clearance is an important technical parameter of the bearing. It directly affects the technical performance of the bearing such as load distribution, vibration, noise, friction, service life and mechanical movement accuracy. Strictly speaking, the dynamic load rating of the bearing changes with the size of the clearance. The load ratings (C and C0) listed in the product catalog are for zero operating clearance. If the clearance is too large, the internal load-bearing area of the bearing will be reduced, the stress on the rolling contact surface will increase, the movement accuracy of the bearing will decrease, the vibration and noise will increase, and the service life of the bearing will be shortened. If the clearance is too small, it will cause heat generation and temperature rise. It may even cause the bearing to "seizure" during operation. Therefore, it is important to select different levels of bearing clearance according to the type of bearing and working conditions.

Standard Deep Groove Ball Bearing skf bearings have internal clearances of C2, standard (CN), C3, C4 and C5, all of which are in compliance with GB4604. ·The radial clearance of deep groove ball bearings is shown in the table below.
