Friction
In this paper, an equation for the calculation of the frictional torque of a dry-lubried tapered roller bearing (TRB) is provided in which the effect of the roller skewing is emphasized. Calculations were performed to investigate the effect of the roller skewing on the torque of dry-lubried TRB for two representative preload methods, that is, axial force preload and axial …

Selecting preload | SKF | SKF
When adjusting preload in a bearing system, it is important that the established preload value is attained with the least possible variation. To reduce variation when mounting tapered roller bearings, the shaft should be turned several times to safeguard that the rollers are in correct contact with the guide flange of the inner ring.
