Imperial miniature bearings for shaft sizes from 0.0937" to 1.00" Imperial miniature bearing with shields

SMB offer a range of imperial miniature ball bearings from stock in the UK with bore sizes as small as 0.0937”.  These miniature bearings can be supplied open or shielded and some sizes are available with rubber seals.

The smaller sizes are sometimes referred to as instrument bearings or micro bearings. We provide inch sizes for applications as varied as gyros, anemometers, small motors and radio controlled models.  

Our inch miniature ball bearings are manufactured in SAE52100 chrome steel and can withstand heavy radial loads and moderate thrust loads in both directions. Some of these sizes can be supplied with Teflon seals.
