Basic rating life calculation | SKF

The extra large grease reservoir in those bearings extends relubriion intervals and bearing service life, especially in appliions where there are constant direction loads (). These advantages are considered in the calculation of the basic rating life by the coloured regions in diagrams for angle of oscillation b 5 ( diagram 4 ) and diagrams for factor f β ( diagram 5 ).

The grease life factor concept for ball bearings - ScienceDirect

25/1/2022· The angular contact bearings 7204 that were used in the R0F+ have similar outer dimensions as the 6204 deep groove ball bearing. However, more grease was used here: 2.3 ml. This corresponds to f =0.4 filling and it can therefore be expected that the life with the reference grease will be a factor 1.7 longer.

Bearing rating life | SKF

For modern high-quality bearings, the calculated basic rating life can deviate significantly from the actual service life in a given appliion. Service life in a particular appliion depends not only on load and bearing size, but also on a variety of influencing factors including lubriion, degree of contamination, proper mounting and other environmental conditions.
