Preload of bearing | DK-BEARING

5/5/2020· For angular contact ball bearings and tapered roller bearings, when preload is applied to increase rigidity, most of them use back-to-back asseled bearings. The back-to-back assely bearing has a large distance between the points of action and the shaft system has strong rigidity.

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.
