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.
