Quality ratings for super precision and spindle bearings are also available from the Anti-friction Bearing Manufacturers Association (AFBMA), the American National Standards Institute (ANSI), the International Organization for Standardization (ISO), Japanese Industrial Standards (JIS), and Deutsch Indusrite Norm.

Specifications for super precision and spindle bearings include bore size, outside diameter, and materials of construction. The bearing industry uses a standard numbering system for bearings with metric-diameter bores.
