RKS Crossed Cylindrical Roller Slewing Bearings - BRS Bearing

RKS cylindrical roller slewing bearings are designed for appliions where stiffness and high rotation accuracy are required. They are divided into three types: external gear type(RKS.161 series), internal gear type(RKS.162 series), without gear type(RKS.160 series). And part of the models has the same mounting dimensions as RKS.061/RKS.062

Influence of Preloading Method of Cylindrical Roller Bearing

Aug 07, 2020· With the increase of preload, the radial, axial and angular stiffness of cylindrical roller bearings increase slightly, but the effect is small. Compared with positioning preload, this effect is more significant for constant pressure preload. This is because the increase in the pre-tightening load increases the contact angle of the inner and
