Miniature Bearings

Miniature Bearings are available open, shielded or sealed, with bore sizes as small as 1 mm. The smaller sizes are sometimes referred to as instrument bearings or micro bearings.

We provide customers with rc bearings for remote-controlled cars, thin section bearings, ceramic bearing for bicycles, and skateboard bearings designed to provide a longer, smoother ride.
