Self Aligning Ball Bearings 1308K

Self Aligning Ball Bearings 1308K

The 1308K is a self-aligning ball bearing with a 40mm tapered bore and 90mm outer diameter, crafted from sturdy chrome steel. It manages radial loads up to 7605 lbf and operates smoothly at speeds up to 9500 RPM.

Its double-row design and open seal allow for slight misalignment adjustments, while the nylon cage reduces friction. The bearing performs reliably in temperatures from -30°C to 110°C.

This model is interchangeable with SKF bearings, offering a practical replacement option. Suitable for machinery where alignment flexibility is needed, like conveyor systems or agricultural equipment.

Weighing 0.68kg, it’s a robust yet manageable size. Compliant with RoHS and REACH standards for safe use.
