|The factors that influence SKF bearing performance and service life include but are not limited to the following :|
Roller end/flange contact area
The geometry and surface finish of the roller ends and the area on the flange that makes contact with the roller ends, have been optimized to promote and maintain the formation of a lubricant film. This reduces friction and heat generated by the bearing as well as flange wear. The bearings can better maintain preload and run at reduced noise levels.
To increase service life under misalignment or heavy load conditions, SKF tapered roller bearings have either crowned raceways or a logarithmic profile to prevent stress peaks at the roller ends. The logarithmic profile is designed to optimize load distribution along the rollers.
Consistency of profiles and roller size
The rollers used in SKF tapered roller bearings are made to such close tolerances that they are virtually identical. These extremely close tolerances, together with the precision of the raceway profiles, provide optimal load distribution over the rollers, to reduce noise and vibration levels and enable preload to be set more accurately.
Tapered roller bearings typically have a running- in period. During the running-in period, a conventional design tapered roller bearing experiences a significant amount of friction, resulting in wear, which can be noticed as a temperature spike. With current SKF tapered roller bearing designs, friction, wear and frictional heat are significantly reduced, provided the bearings are mounted and lubricated correctly.
