ISO 20056-1:2017规定了混合轴承的动载荷额定值计算方法，该轴承的轴承环由当代常用的高质量硬化轴承钢制成，符合良好制造规范，滚动元件由当代常用的高材料氮化硅制成，制造质量和表面光洁度。对于球，ISO 26602[6]和ISO 3290-2[2]适用。对于滚筒，ISO 12297？2[3]适用，ISO 26602[6]以类似方式适用。

ISO 20056-1:2017 specifies methods of calculating the dynamic load ratings for hybrid bearings with bearing rings made of contemporary, commonly used, high quality hardened bearing steel, in accordance with good manufacturing practice and rolling elements made from silicon nitride in contemporary, commonly used, high material and manufacturing quality and surface finish. For balls, ISO 26602[6] together with ISO 3290？2[2] are applicable. For rollers, ISO 12297？2[3] is applicable and ISO 26602[6] is applicable in an analogous way.
