Rollix rollers range

Our standard crossed rollers range includes all single and double-row rollers slewing rings. All slewing rings are preloaded.

Why choose standard crossed rollers slewing rings?

Linear contact between the roller and the raceway limits contact pressure and therefore increases service life. The crossed rollers arrangement allows axial and radial loads to be accepted, while ensuring good rigidity of the assembly.

It should be noted that the rigidity of the supports is very important in order to guarantee proper operation of the crossed rollers slewing rings.

Double row slewing rings provide greater load capacity in a confined environment.
