This Standard defines the thermal speed rating for rolling bearings and calculation principles.<\/p>\n

\nThe parameter determined in accordance with this Standard applies to rolling bearings of the given series and sizes of standard design specified in JIS B 1511 or of a design that, from a frictional point of view, can be related to a standard design bearing.<\/p>\n

\nThrust ball bearings are excluded from this Standard as kinematic effects do not allow the thermal speed rating defined in this Standard to be applied.<\/p>\n

\nNOTE 1 In Annex A mean values for coefficient for for calculation of the loadindependent frictional moment and coefficient f1r for calculation of the load-dependent frictional moment under reference conditions in clause 5 are given.<\/p>\n

\nNOTE 2 In Annex B the reference conditions for grease lubrication are defined.<\/p>\n

\nThe reference are chosen such that the thermal speed rating for grease lubrication is identical to that for oil bath lubrication.<\/p>\n

\nNOTE 3 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows:<\/p>\n

\nISO 15312: 2003 Rolling bearings-Thermal speed rating-Calculation and coefficients (IDT)<\/p>\n

\nThe symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO\/ lEC Guide 21-1.<\/p>\n","protected":false},"excerpt":{"rendered":"
