Stainless steel miniature bearings for shaft sizes from 0.6mm to 9mm.
SMB Bearings supply a range of stainless steel miniature ball bearings from stock in the UK with bore sizes as small as 0.6mm. The bearings in the table below are available open, shielded or sealed. Stainless steel gives these miniature bearings corrosion resistance. We also supply corrosion resistant miniature bearings in other materials such 316 stainless steel or acetal resin.
These small stainless steel bearings are sometimes referred to as instrument bearings or micro bearings. We provide stainless steel metric sizes for applications as varied as medical instruments, gyros, anemometers and fishing reels.
Our metric stainless steel miniature ball bearings are supplied in AISI440C or KS440 (ACD34/X65Cr13) stainless 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.
