- Scope
- This standard specifies the calculation method of basic rated static load and equivalent static load of rolling bearings. This standard applies to rolling bearings whose size range complies with relevant national standards, is made of commonly used high-quality hardened bearing steel, manufactured according to good processing methods, and the shape of the rolling contact surface is basically of conventional design. This standard does not apply to bearings where the contact area between the rolling elements and the ring raceway is obviously cut off due to the service conditions or (and) the internal structure of the bearing. If the calculation is carried out according to this standard, satisfactory results cannot be obtained. Similarly, this standard does not apply to occasions where the load in the bearing deviates from the normal distribution due to service conditions, such as tilting, preload or excessive clearance, surface treatment or coating, etc. If these situations occur, the user should consult with the bearing manufacturer on how to calculate the equivalent static load. This standard also does not apply to the structure of rolling elements running directly on the surface of the shaft or housing, unless these surfaces are in all respects equivalent to the raceway surface of the bearing ring it replaces. For double row radial bearings and bidirectional thrust bearings, if referring to this standard, it should be assumed that their structure is symmetrical. In addition, this standard is also applicable to the determination of the static safety factor under heavy load conditions.
