Stainless steel miniature bearings for shaft sizes from 0.04" to 1.00".
SMB Bearings provide stainless steel miniature ball bearings and small ball bearings with bore sizes as small as 0.04” from stock in the UK. Stainless steel provides corrosion resistance. We also supply corrosion resistant miniature bearings in POM/acetal resin and other materials.
The smaller sizes are sometimes referred to as instrument bearings or micro bearings. We provide inch sizes for applications as varied as gyros, anemometers, medical or dental instruments and fishing reels.
These inch miniature ball bearings are manufactured in AISI440C or KS440 stainless steel and can withstand heavy radial loads and moderate thrust loads in both directions. Many sizes are available with an extended inner ring. Some can also be supplied with Teflon seals.
