Roller Slewing Rings

triple row

This type of slewing ring is built with three independent rows of rollers, the upper, lower, and radial raceways are separated so that a load of each row of rollers can be accurately determined. It can bear various loads at the same time and has the largest loading capacity among all types of slewing rings. It has large dimensions and robust structure, especially suited for heavy machinery that requires larger diameters.


Available with inner gear, outer gear or no gear


Can accomodate very high loads and tilting moments


Equipped with sealing and lubrication system

Dimensions and Tolerances

The general tolerances of slewing rings conform to ISO 286-1 and ISO 286-2. The boundary dimensions of slewing rings are not standardized. Please contact our technical department to get our slewing rings catalogue.

Bearing Clearance

Clearance for slewing rings is not standardized. ALPHA slewing rings can be supplied with different clearance or preload tolerances, based on the application type.
