The ring of the 6307C4 mining pulley bearing:
The ring is the main part of the 6307C4 mining pulley bearing. Best 6307C4 mining pulley bearing has deep groove ball, and large clearance. But deep groove doesn’t mean to dig the channel with a simple way of enlarge the steel ball. The thickness of the bearing is certain, so to get the ball big and the groove deep will shorten service life. Our XKTE bearing uses way of thickening ring to get the standard of deep groove and large clearance, improves the anti-stuck performance, and effectively increases the service life.
