Flanged Miniature Bearings
Inch series for shaft sizes from 0,04" to 0.625"
Chrome steel and stainless steel

Flanged miniature bearings are available open, shielded or sealed.with bore sizes as small as 0.04 inches. The smaller sizes are sometimes referred to as instrument bearings. Available in SAE52100 chrome steel and AISI440C or KS440 (ACD34/X65Cr13) stainless steel, these inch sized deep groove radial flanged miniature ball bearings can withstand heavy radial loads and moderate thrust loads in both directions. Flanged miniature bearings have an outer ring flange to facilitate location in a housing.

Many of these flanged miniature bearings can be supplied to order with ceramic balls (hybrid bearings). Most sizes are available in stainless steel or passivated stainless steel for more corrosive environments (see Technical Data - Bearing Material).
