Miniature Bearings for shaft sizes from 1.5mm to 9mm.
The miniature bearings in the table below (mini bearings) and small bearings are available open, shielded or sealed, with bore sizes as small as 1.5mm.
The smaller sizes are sometimes referred to as instrument bearings or micro bearings. We provide metric sizes for applications as varied as gyros, anemometers, miniature gearboxes, small motors and radio controlled models.
Our chrome steel metric miniature bearings are supplied in SAE52100 chrome steel and can withstand heavy radial loads and moderate thrust loads in both directions. Certain sizes can be supplied with the TW high-speed synthetic cage.
