SKF-RKS Crossed Cylindrical Roller Slewing Bearings

RKS series crossed cylindrical roller slewing bearings consist of a solid one-piece inner and outer ring, a set of cylindrical rollers and spacers, and sealings. Since the axis of rotation of adjacent rollers are at 90° to each other, RKS cross roller slewing bearings can accommodate heavy radial loads and medium axial loads as well as tilting moments.

RKS Crossed Roller Slewing Ring Features And Classifications

RKS cylindrical roller slewing bearings are designed for applications where stiffness and high rotation accuracy are required. They are devided into three types: external gear type(RKS.161 series), internal gear type(RKS.162 series), without gear type(RKS.160 series). And part of models have same mounting dimensions as RKS.061/RKS.062/RKS.060 series four point contact ball slewing bearings, so they can be used interchagably.
