YRTM Rotary Table Bearing

YRTM Rotary Table Bearing

Axial and radial bearing YRTM with the angle measuring systemis based on the YRT bearing; it is mounted with angle measuring system on the YRT bearing, in order to accurately measure and adjust the angle of the bearing rotating and make sure the high rotation speeds. Measuring system is composed of transmission chain and measuring scale. It adopts pure inductive measurement principle, so the signal, its precision and the precision of measuring is very high.And by using high protective measures, the measurement system will be not disturbed in operation from external ambience, such as Smoke and Dust, mild pollution and scratches, magnetic field. I can work reliably without too much maintenance; the application scope is very wide. It can be applied to high precision rotary table and axis rotation, index head, military radar, aviation, aerospace and the field with the high accuracy of Angle rotation in the measuring and the test.

Remark:
1)Including retaining screws and threaded extraction holes.
2)Referring installing screws.
3)Bearing frictional torque must test by speed 5r/min,the stattup frictonal torque should be 2-2.5times of listed date.
