NSK 6210-2RS/C3 Rubber Sealed Single Row Deep Groove Ball Bearing 50x90x20mm

The NSK 6210-2RS-C3 is a premium single-row deep groove ball bearing (50mm bore x 90mm outside diameter x 20mm width) engineered for demanding applications requiring both superior contamination protection and enhanced thermal clearance. Featuring integral contact rubber seals on both sides (2RS) , this bearing provides an effective barrier against dust, moisture, and contaminants while securely retaining the factory-applied grease for extended maintenance-free operation. The C3 radial internal clearance accommodates thermal expansion during high-speed operation, preventing unwanted preload and ensuring consistent performance under fluctuating temperatures. Manufactured by NSK to exacting Japanese quality standards, this bearing accommodates both radial and axial loads with minimal friction, delivering reliable, low-vibration performance with a dynamic load rating of 35 kN, a static load rating of 23.2 kN, and a limiting speed of 4,800 rpm. The 6210-2RS-C3 is ideally suited for electric motors, pumps, gearboxes, agricultural machinery, and conveyor systems where both environmental exposure and thermal variation are concerns.
