Miniature Bearings for shaft sizes from 1.5mm to 9mm.A chrome steel miniature bearing with shields

SMB supply a range of miniature ball bearings and small bearings from stock in the UK.  These chrome steel miniature bearings are available open, shielded or sealed with bore sizes as small as 1.5mm.


Miniature bearings 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 metric miniature ball 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.
