6301-2RS Shielded Ball Bearings


6301-2RS is a small ball bearing with rubber seals and grease on both sides for power tools such as hammers and picks, Logistics transmission equipment, electric bicycles, roller skating toys and other products.

Ball-bearing inner dimension 12mm X outer dimension 37mm X width 12mm.

6301-2RS single row deep groove ball bearing applications include clutches, drives, gearboxes, compressors, pumps, turbines, and printing and textile machines.

Due to the spherical shape of the balls, only the tops of the balls run on the raceway. Since it has a point contact with the raceway, unlike the line contact in a roller bearing, lower friction and higher-rated speeds can be achieved.
