SKF 6308-2RSJEM Deep Groove Ball Bearing

SKF 6308-2RSJEM is a single-row deep groove ball bearing with seals on both sides, delivering robust radial support in a compact 40 mm bore, 90 mm outer diameter, and 23 mm width. The bearing is made from bearing steel and uses a sheet metal cage, with grease lubrication and no relubrication feature. It features radial internal clearance classified as C3, allowing higher speed and greater misalignment tolerance within its class. The dynamic load rating is 42.3 kN and the static load rating is 24 kN, indicating strong capability to sustain radial loads in general- purpose machinery. The double-seal configuration (2RS) provides contamination protection while maintaining lubrication, making it well suited for motors, gearboxes, fans, and other moderate-load applications where low maintenance and reliable sealing are important. The JEM designation accompanies the standard 6308-2RS features, and the dimensions align with ISO 6308 series norms, ensuring interchangeability with SKF and other manufacturers’ 40x90x23 mm bearings. In operation, you can expect a compact bearing that supports steady, low-friction rotation at moderate speeds, with a limiting speed around 5,000 rpm depending on mounting, lubrication, and load conditions.
