ISO 20056-2:2017规定了计算混合轴承静载荷额定值的方法，该轴承的轴承环由当代常用的高质量硬化轴承钢制成，符合良好的制造规范，以及由氮化硅（Si3N4）制成的全套滚动元件，采用当代常用材料和制造质量。对于球，ISO 26602、[4]和ISO 3290-2、[1]适用。对于滚筒，ISO 12297？2[2]适用，ISO 26602[4]以类似方式适用。 对于使用混合轴承的应用，应遵守表1和表2规定的静态安全系数S0的指导值。

ISO 20056-2:2017 specifies methods of calculating the static 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 a full set of rolling elements made of silicon nitride (Si3N4) in contemporary, commonly used material and manufacturing quality. For balls, ISO 26602,[4] together with ISO 3290？2,[1] is applicable. For rollers, ISO 12297？2[2] is applicable, and ISO 26602[4] is applicable in an analogous way. For applications where hybrid bearings are used, guideline values of the static safety factor, S0, according to Table 1 and Table 2 are observed.
