NSK Rubber Sealed Deep Groove Ball Bearings are designed to deliver superior protection, long-lasting performance, and enhanced reliability in demanding environments where dust, moisture, and contaminants are present. Produced by NSK Ltd., these bearings feature high-quality rubber seals that effectively retain lubricant while preventing the ingress of harmful particles, significantly extending bearing life and reducing maintenance requirements. Ideal for applications such as electric motors, automotive components, agricultural equipment, and industrial machinery, NSK rubber sealed bearings provide smooth, quiet operation with excellent resistance to wear and corrosion.
The NSK 6210-2RS is a premium single-row deep groove ball bearing (50mm bore x 90mm outside diameter x 20mm width) engineered for reliable, maintenance-free operation in applications where contamination protection is critical. 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 service life without the need for relubrication. Manufactured by NSK to exacting quality standards, this bearing accommodates both radial and axial loads with minimal friction, delivering consistent, 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 with grease lubrication, the 6210-2RS is ideally suited for electric motors, pumps, gearboxes, agricultural machinery, and conveyor systems where both environmental protection and durability are paramount.
