6217-2RSJEM Bearing Product Overview & Core Advantages
The 6217-2RSJEM is a sealed single row deep groove ball bearing engineered for robust performance in demanding applications. This metric bearing features integrated rubber seals (2RS) on both sides, providing superior contamination protection while retaining lubrication. Manufactured to ABEC 1 | ISO P0 precision standards with CN radial internal clearance, it delivers reliable operation and long service life. Its design excels at handling high radial loads while accommodating moderate axial loads in both directions, making it an excellent choice for industrial machinery requiring dependable, maintenance-free operation within a wide temperature range of -30°C to 120°C.
