Thrust/radial bearings are units of bi-directional thrust bearings installed together with bolts and a radial guide bearing. These ready to install and pre lubricated units have high rigidity, strong load-bearing capacity, and particularly high operational accuracy. It can support radial force, bidirectional axial force, and tilt moment without clearance. Thrust angular contact ball bearings are low friction, ready to install, lubricated bearing units with high precision, suitable for high requirements such as extremely high speeds, high axial and radial loads, and high tilt stiffness. The axial radial bearings YRTM and YRTSM with angle measurement systems correspond to the series YRT and YRTS in mechanical terms, but are additionally equipped with angle measurement systems.
