Self Aligning Ball Bearings 2308-K 2RS

Self Aligning Ball Bearings 2308-K 2RS

The 2308-K 2RS is a self-aligning ball bearing with a 40mm tapered bore and 90mm outer diameter, built to handle radial loads. Its compact 33mm width fits snugly in tight spaces, while the double-row design offers stability.
Made from chrome steel with a nylon cage, it supports dynamic loads up to 7605 lbf and spins smoothly at 4800 RPM. The sealed design keeps lubrication in and contaminants out.
This bearing adjusts to minor misalignments, reducing wear in uneven setups. It’s ideal for machinery like conveyors or agricultural equipment where alignment isn’t perfect.
Weighing 0.96kg, it’s robust yet manageable. Compliant with RoHS and REACH standards, it’s a reliable choice for replacements, especially where SKF compatibility is needed. Works well in temperatures from -30°C to 110°C.
