High Precision Bearings for Combined Loads, Axial/radial bearings YRTS
Axial/radial bearings are double direction axial bearings for screw mounting, with a radial guidance bearing. These ready-to-fit,greased units are very rigid, have high load carrying capacity and run with particularly high accuracy. They can support radial forces,axial forces from both directions and tilting moments free from clearance.
For the bearing arrangements of direct drive axes, there is the series YRTS. Due to their high limiting speeds and very low,uniform frictional torque across the whole speed range, these bearings are particularly suitable for combination with torque motors.
For higher accuracy requirements, these bearings are also available with restricted axial and radial runout accuracy.
