Rotek Series 10,000 slewing bearings are built with three independent rows of rollers. Since all loads are transmitted directly to raceway surfaces, which are perpendicular to the load direction, the capacity of each rolling element and each raceway surface is utilized in the most efficient manner.
The three-row roller slewing bearing offers more capacity per unit size than any other Rotek slewing bearing design and is inherently the stiffest style of construction. Frictional torque is lower than other styles under most load conditions.
