NSK 6211-2Z Metal Shielded Single Row Deep Groove Ball Bearing 55x100x21mm

The NSK 6211-2Z is a premium single-row deep groove ball bearing featuring a 55mm bore, 100mm outside diameter, and 21mm width. This bearing is equipped with non-contact metal shields on both sides (2Z) that effectively exclude larger particulates and debris while securely retaining the factory-applied grease, with the shield design minimizing frictional drag to support elevated rotational speeds. Manufactured to NSK's exacting Japanese quality standards, this bearing accommodates both radial and axial loads in either direction with minimal friction, delivering consistent, low-vibration performance with a dynamic load rating of 47.5 kN and a static load rating of 29.3 kN. With a grease lubrication limiting speed of approximately 8,000 rpm, the 6211-2Z is ideally suited for electric motors, pumps, fans, compressors, and general industrial machinery where a balance of contamination protection and high-speed capability is required. Featuring a pressed steel cage and normal (CN) radial internal clearance, this bearing delivers consistent performance across a standard operating temperature range.
