Slewing bearing/ Slewing ring Rotational resistance

Slewing bearing/ Slewing ring  Rotational resistance

The rotational resistance of slewing rings is essentially
determined by:
 the rolling resistance of the rolling elements
 the internal clearance or bearing preload
 the friction of the spacers or the cage or cage segments
 the seals.
The rotational resistance is also influenced by a large number of other parameters.
These include:
 the preload and lubrication of the seals
 the quantity of grease in the bearing
 the manufacturing tolerances
 the change in the internal clearance due to fitting
 the deformation of the adjacent construction.
