Miniature/ Thin Bearings

Miniature

Miniature Bearings for shaft sizes from 0.6mm to 9mm chrome steel and stainless steel.

Chrome steel miniature bearings (mini bearings) and small bearings are available open, shielded or sealed, with bore sizes as small as 1.5mm. 

The smaller sizes 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 chrome steel metric miniature bearings are supplied in SAE52100 chrome steel and, like most deep groove radial ball bearings, can withstand heavy radial loads and moderate thrust loads in both directions. Certain sizes can be supplied with the TW high-speed synthetic cage.
