SW 6203-2RS Deep Groove Ball Bearing | 17x40x12mm Sealed | Industrial High-Speed Standard
The SW 6203-2RS is a robust, single-row deep groove ball bearing designed for versatility and exceptional performance across a wide range of industrial applications. Featuring a 17mm bore, 40mm outer diameter, and 12mm width, this precision component is the workhorse standard for motors, pumps, conveyors, and light machinery requiring reliable rotational support. The '2RS' designation indicates double lip rubber seals installed on both sides, effectively retaining SW's proprietary high-performance grease while guarding the raceways against dust, moisture, and contamination, thereby ensuring maintenance-free operation and significantly extending service life. Engineered for balanced load handling, the 6203-2RS efficiently manages moderate radial loads and light axial loads in both directions.
Built to rigorous SW specifications, this bearing utilizes high-grade 52100 bearing steel and precision-honed raceways to minimize friction and thermal output, optimizing energy efficiency even at high rotational speeds up to 15,000 RPM (grease lubricated). SW's commitment to quality ensures superior dimensional accuracy and running stability, providing reduced vibration and lower noise levels than commodity alternatives. Choose the SW 6203-2RS for demanding operational environments where bearing longevity, reliability, and precision are critical components of minimizing downtime and maximizing machinery productivity.
