NSK 6210-2Z/C3 Metal Shielded Single Row Deep Groove Ball Bearing 50x90x20mm

The NSK 6210-2Z-C3 is a precision single-row deep groove ball bearing (50mm bore x 90mm outside diameter x 20mm width) engineered for high-speed applications requiring both contamination protection and thermal clearance management. Featuring non-contact metal shields on both sides (2Z) , this bearing effectively excludes particulates while retaining factory-applied grease, with minimal frictional drag to support elevated rotational speeds. The C3 radial internal clearance accommodates thermal expansion during operation, preventing internal 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 and a static load rating of 23.2 kN. With grease lubrication limiting speeds of approximately 8,000 rpm, the 6210-2Z-C3 is ideally suited for electric motors, fans, compressors, pumps, and gearboxes where both speed and thermal variation are factors.
