GB/T 4662-2003 in English

《GB/T 4662-2003滚动轴承 额定静载荷》由TC98（全国滚动轴承标准化技术委员会）归口，主管部门为中国机械工业联合会。
本标准规定了滚动轴承基本额定静载荷和当量静载荷的计算方法。本标准适用于尺寸范围符合有关国家标准规定、采用优质淬硬钢、按照良好的加工方法制法、且滚动接触表面的形状基本上为常规设计的滚动轴承。

Scope

This standard specifies the calculation method of basic rated static load and equivalent static load of rolling bearings. This standard is applicable to rolling bearings whose size range complies with relevant national standards, is made of high-quality hardened steel, manufactured according to good processing methods, and the shape of the rolling contact surface is basically of conventional design. This standard is not applicable 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. Likewise, this standard does not apply to occasions where the load in the bearing deviates from the normal distribution due to service conditions, such as inclination, preload or excessive clearance. 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 rolling elements running directly on shaft or housing surfaces unless these surfaces are equivalent in all respects to the raceway surfaces of the bearing rings they replace. For double-row radial bearings and double-direction thrust bearings, if referring to this standard, it should be assumed that their structure is symmetrical.
