A deep groove ball bearing is one of the most widely used rolling bearings. They are used to accommodate radial and axial loads in both directions. Suitable for all kinds of industrial equipment, agricultural machinery, conveying equipment, robots, dental equipment, elevator micro motors, small rotary motors, office equipment, etc. Yuanhe deep groove ball bearings have low friction and high upper limit speed, are cost-effective and have almost no maintenance.

Deep groove ball bearings are made of bearing steel for durability and resistance to rust, corrosion, and deformation, and shields on both sides prevent lubricant ingress and contaminants.
