SW 6203-2RSNR Deep Groove Ball Bearing - Sealed, Snap Ring (17x40x12 mm)
The SW 6203-2RSNR is a premium deep groove ball bearing engineered for standard industrial applications requiring high reliability and axial positioning stability. Featuring a standard 17mm bore, 40mm outer diameter, and 12mm width, this bearing incorporates double non-contact synthetic rubber seals (-2RS) on both sides. This sealing configuration effectively retains internal grease while providing excellent protection against dust, moisture, and fine particulate contamination, drastically extending the service life in harsh MRO (Maintenance, Repair, and Operations) environments. Furthermore, the ‘NR’ designation signifies that the bearing is supplied with a snap ring and has the corresponding snap ring groove machined into the outer diameter, enabling precise and simplified axial location within the housing without requiring additional complex component machining.
Built to rigorous ISO standards, the SW 6203-2RSNR provides a high dynamic load capacity essential for electric motors, gearboxes, pumps, and agricultural machinery operating under moderate radial and minor axial loads. The precision manufacturing ensures low friction torque and reduced operational noise levels. As a Senior Product Manager, we recommend this bearing for customers seeking a standardized, readily available solution that minimizes installation complexity and maximizes uptime through superior contaminant exclusion. Its robust design and integrated snap ring feature make it an efficient and cost-effective inventory choice for high-volume maintenance planning.
