The ring of the 6308-2RS conveyor drum bearing:
The ring is the main part of the 6308-2RS conveyor drum bearing. Best 6308-2RS conveyor drum 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.
Bearing material and hardness:
Good 6308-2RS conveyor drum bearing must be made of bearing steel, named High Carbon Chromium Bearing Steel (Fully quenched class) GCr15. At present the standard hardness of 6308-2RS conveyor drum bearing is 60-65 degree, while hardness of ring is 61-62 degree, and ball is 64-65 degree. The simple way to identify 6308-2RS conveyor drum bearing is to see if its hardness is over 60 degree, because only bearing steel can get over this degree.
