Rolling bearings -- Thermal speed rating -- Calculation and coefficients
This standard has been revised by ISO 15312:2018
ISO 15312:2003 defines the thermal speed rating for oil bath lubricated rolling bearings and defines calculation principles for the determination of this parameter. The parameter determined in accordance with this International Standard applies to rolling bearings of the given series and sizes of standard design or of a design that, from a frictional point of view, can be related to a standard design bearing.
Thrust ball bearings are excluded from ISO 15312:2003 as kinematic effects do not allow the thermal speed rating defined in this International Standard to be applied.
