Miniature Ball Bearings with Extended Inner Ring RW2

Miniature Ball Bearings with Extended Inner Ring RW2

The RW2 is a compact miniature ball bearing with a 0.125″ bore and 0.375″ outer diameter, crafted from sturdy chrome steel. Its extended inner ring design offers easier handling and mounting in tight spaces.

This single-row bearing supports radial loads up to 121 lbf and spins smoothly at speeds up to 56,000 RPM. The open seal type allows for straightforward lubrication when needed.

With a lightweight build at just 1.37g, it’s ideal for small mechanisms like precision instruments or miniature motors. The bearing operates reliably in temperatures from -86°F to 230°F.

Compliant with RoHS and REACH standards, it’s a practical choice for both industrial and hobbyist applications where space is limited but performance matters.
