YRTS Rotary Bearing

YRTS Rotary Bearing

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

The parameter as follows:

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 .
