BS ISO 76:2006+A1:2017规定了相关ISO标准所示尺寸范围内滚动轴承的基本静载荷额定值和静等效载荷的计算方法，这些轴承由当代、常用、高质量的材料制成，硬化轴承钢符合良好的制造规范，基本上是关于滚动接触面形状的常规设计。对于由于应用条件和/或内部设计，滚动元件和环形滚道之间的接触面积有相当大的截断的轴承，根据本国际标准进行的计算不会产生令人满意的结果。同样的限制适用于应用条件导致轴承中的正常负载分布发生偏差的情况，例如未对准、预载或超大间隙，或使用特殊表面处理或涂层的情况。 如果有理由认为这种情况普遍存在，用户应咨询轴承制造商，以获得建议和静态等效载荷的评估。交叉引用:ISO 15241ISO 5593ISO 10657:1991（R05）包含以下内容:修正案，2017年12月

BS ISO 76:2006+A1:2017 specifies methods of calculating the basic static load rating and the static equivalent load for rolling bearings within the size ranges shown in the relevant ISO standards, manufactured from contemporary, commonly used, high quality, hardened bearing steel in accordance with good manufacturing practice and basically of conventional design as regards the shape of the rolling contact surfaces.Calculations carried out in accordance with this International Standard do not yield satisfactory results for bearings in which, because of application conditions and/or internal design, there is a considerable truncation of the area of contact between the rolling elements and the ring raceways. The same limitation applies where application conditions cause deviations from a normal load distribution in the bearing, for example misalignment, preload or extra large clearance or where special surface treatment or coatings are used. Where there is reason to assume that such conditions prevail, the user should consult the bearing manufacturer for recommendations and the evaluation of the static equivalent load.Cross References:ISO 15241ISO 5593ISO 10657:1991 (R05)Incorporates the following:Amendment, December 2017
