YRTS rotary bearing

Axial/radial bearings 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.
Bearing features:
1.   High precision: precision at P4, P2.
2.   High rigidity: YRT series bearings are with preload.
3.   High load capacity: bearings can support axial load, radial load and tilting load.
4.   High speed: YRTS series bearings can be applied in the high speed working condition.

Application scope:
     YRT series bearings are widely used high precision rotary table, vertical grinding machine, dividing head, hobbing machine, gear generator axis etc.

Remark:
1)including retaining screws and threaded extraction holes.
2)note install screws.
3)Bearing frictional torque must test by speed 5r/min , the sartup frictonal torque should be 2-2.5 times of listed data .
