JB/T 6637-2004Technical requirements for rolling bearing reference standards (English PDF)

1 Scope

This Standard specifies such technical requirements as tolerance, acceptance regulations, rust proof and package of standard used for rolling bearings and their parts inspection.

This Standard is applicable to standard with the following dimensions used for rolling bearing.

- Nominal inside diameter of standard used for rolling bearing cylindrical bore is 0.6 mm ~ 400 mm;

- Nominal outside diameter of standard used for rolling bearing cylinder is 2.5 mm ~ 500mm;

- Nominal inside diameter of standard used for rolling bearing tapered bore is less than or equal to 500mm;

- Diameter of standard used for outer ring raceway of tapered roller bearing is 18mm ~ 500mm;

- Diameter of standard used for inner ring raceway of tapered roller bearing is 18mm ~ 400mm;

- Width of standard used for rolling bearing width is less than or equal to 400mm;

- Nominal diameter of standard used for tapered roller is less than or equal to 120 mm.
