Notes:
1. Angular contact thin section ball bearings are typically manufactured from
440C stainless steel.
4. Part numbers listed are with outer ring relieved configuration. Other design
options are available.
2. Load ratings shown are for 52100 chrome steel.
5. Fillet Radius (r) is the maximum shaft or housing fillet radius that bearing corners
will clear.
3. NHBB typically manufactures thin section bearings to ABEC 5T and 7T tolerances
per AMBA Standard 12 (bore diameters up to 1.6250 inches) and ABEC 5F and
7F tolerances per ABMA standard 26 (bore diameters above 1.6250 inches).
