6303-2RS Shielded Ball Bearings

6303-2RS is a small ball bearing with rubber seals and grease on both sides for power tools such as angle grinders, hammers and picks.

Ball-bearing inner dimension 15mm X outer dimension 35mm X width 11mm, durable, double-sided seal, can effectively prevent contamination from entering the bearing chamber, ideal for high speed and heavy radial and axial loads.

6303-2RS single row deep groove ball bearing has the highest speed rating of all bearing types. 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.
