Miniature bearings

Flanged stainless steel miniature bearings for shaft sizes from 0.04" to 0.50".

Our flanged stainless steel miniature ball bearings (mini bearings) and small bearings are available open, shielded or sealed, with bore sizes as small as 0.04”. The flange allows easier location in a housing while stainless steel provides corrosion resistance.

The smaller sizes are sometimes referred to as instrument bearings or micro bearings. We provide inch sizes for applications as varied as gyros, anemometers, dental equipment, medical instruments and fishing reels.

These flanged miniature ball bearings are supplied in AISI440C or KS440 (ACD34/X65Cr13) stainless steel from stock in the UK and, like most deep groove radial ball bearings, can withstand heavy radial loads and moderate thrust loads in both directions.  Many sizes are available with an extended inner ring. In addition, some can be supplied with Teflon seals.
