Self Aligning Ball Bearings 2308K

Self Aligning Ball Bearings 2308K

The 2308K is a self-aligning ball bearing with a 40mm tapered bore and 90mm outer diameter, crafted from sturdy chrome steel. Its double-row design and sealed construction help it handle radial loads up to 7605 lbf while running smoothly at 4800 RPM.

The nylon cage reduces friction, and the pre-lubrication ensures quiet operation. It can withstand temperatures from -30°C to 110°C, making it versatile for various environments.

This bearing aligns itself to minor misalignments, reducing wear and tear. It’s a practical choice for machinery like conveyor belts or agricultural equipment where alignment might shift.

Weighing 0.96kg, it’s robust yet manageable. Compliant with RoHS and REACH standards, it’s a reliable, eco-friendly option for industrial applications.
