This deep groove ball bearing carries radial loads on a single row of balls, with a bore of 10.0 mm, an outside diameter of 30.0 mm, and a width of 14.0 mm. It has a steel sheet metal cage (JN) and weighs 44.0 g. Both sides are sealed with rubbing seals (2RSR), and the design allows a limiting speed of 16700.0 1/min. The radial internal clearance falls in group C2, which is tighter than standard clearance and suits applications where operating clearance must stay reduced under load or with an interference fit. The rubbing seals on both sides keep grease inside the bearing and block dust and moisture from entering, so no external resealing or additional shielding is required after mounting. The steel sheet metal cage keeps the ball set positioned reliably at the stated speed rating without added rotational mass.
