适用范围：This Technical Specification contains recommendations for the calculation of the modified reference rating lifetaking into consideration lubrication, contamination and fatigue load limit of the bearing material, as well astilting or misalignment, operating clearance of the bearing and internal load distribution on rolling elements.The calculation method provided in this Technical Specification covers influencing parameters additional tothose described in ISO 281.The directions and limitations given in ISO 281 apply to this Technical Specification. The calculation methodspertain to the fatigue life of the bearings. Other mechanisms of failure, like wear or microspalling (graystaining), lie outside the scope of this Technical Specification.This Technical Specification applies to tilted single-row radial ball bearings, subjected to radial and axial loadand with radial clearance and tilt taken into account. It also applies to tilted single-row roller bearings,subjected to pure radial load and with radial clearance, edge stress and tilt taken into account. References tomethods for the analysis of the internal load distribution under general load are given.The analysis of internal load distribution and modified reference rating life for multi-row bearings or bearings ofa more complex geometry can be derived from the equations given in this Technical Specification. For thesebearings, the load distribution for each individual row has to be considered.This Technical Specification is primarily intended to be used for computer programs and together withISO 281 covers the information needed for life calculations. For accurate life calculations under the operatingconditions specified above, it is recommended that either this Technical Specification or advanced computercalculations provided by bearing manufacturers, for determining the dynamic equivalent reference load underdifferent loading conditions, be used.
