NSK 6211-2RS Rubber Sealed Single Row Deep Groove Ball Bearing 55x100x21mm

The NSK 6211-2RS is a premium single-row deep groove ball bearing with dimensions of 55mm bore x 100mm outside diameter x 21mm width, engineered for demanding applications requiring maximum protection against contamination and lubricant loss. Manufactured to NSK's stringent Japanese quality standards, this bearing features integral contact rubber seals on both sides (2RS) that provide an effective barrier against moisture, dust, dirt, and abrasive particles while securely retaining the factory-applied grease for extended maintenance-free operation. The seal design delivers superior ingress protection, making the NSK 6211-2RS particularly suited for challenging environments such as agricultural equipment, construction machinery, material handling systems, pumps, and automotive applications where external exposure is a concern. With a dynamic load rating of 47.5 kN and a static load rating of 29.3 kN, this sealed bearing supports both radial and axial loads in either direction with minimal friction, delivering consistent, low-vibration performance at grease lubrication speeds up to 4,800 rpm. Featuring a pressed steel cage and ten precision-ground 14.288mm balls, the NSK 6211-2RS offers exceptional durability, extended lubrication intervals, and reliable service life without the need for relubrication. For maintenance professionals and OEM engineers requiring a fit-and-forget solution in harsh operating conditions, the NSK 6211-2RS delivers uncompromising reliability and performance.
