Ball bearing is a kind of rolling bearing. The ball ball is installed between the inner steel ring and the outer steel ring, and can bear a large load. Also called ball bearing.

The outer ring of the roller bearing adopts a fully loaded cylindrical roller bearing with thick outer ring wall. The outer diameter surface of the roller has cylindrical and arc shape, which can be designed to fit with the raceway surface according to the application situation. With this outer ring, the roller can roll directly on the raceway and can bear heavy load and impact load.

The bearing is a sealed structure, filled with grease, providing long-term effective lubrication, and users can avoid lubrication. For those with poor working conditions, the grease replenishing channel can be designed to improve the service life of the bearing. Improper methods can also cause heating of roller bearings. Lubrication can reduce the wear of parts in motion, ensure the accuracy of the press and reduce energy consumption. Lubrication includes thin oil lubrication and thick oil lubrication.
