Deep Groove Ball Bearing – 6311-2RS1/C3

The SKF 6311-2RS1/C3 deep groove ball bearing delivers a robust, versatile, and low-maintenance solution for machinery requiring reliable sealing and high performance. Its contact seals on both sides keep grease in and contaminants out, ensuring longer service life while reducing the need for relubrication.

Optimized internal geometry minimizes friction, vibration, and noise, enabling efficient operation even at high speeds, with a limiting speed of 3,800 r/min. With a basic dynamic load rating of 74.1 kN, static load rating of 45 kN, and C3 clearance for smooth running under thermal expansion and heavy loads, this SKF Explorer bearing is engineered for durability and consistent performance across motors, gearboxes, pumps, and general machinery.
