Miniature bearings with extended inner ring for shaft sizes from 0,0469" to 0.3125" in stainless steel.A miniature bearing with extended inner ring and metal shields

These stainless steel miniature bearings with extended inner ring have an inner ring that is wider than the outer ring by 0.0312" (0.0156" on each side. These bearings are easier to mount with the wider inner ring eliminating the need for spacers or washers.


Some sizes may be available in SAE52100 chrome steel but these are more usually supplied in AISI440C or KS440 (ACD34/X65Cr13) stainless steel. These extended inner ring miniature bearings can withstand heavy radial loads and moderate thrust loads in both directions.
