YRT80 High Accuracy China Rotary Table Bearings /INA quality

YRT basic rotary table bearings are designed with a radial full roller, two groups of axial needle roller, cage assembly, an out ring, an L-section inner and the second ring. The out ring and inner ring have fixing holes, so the bolt can fix the bearings directly. HONBbearing07.YRT rotary table bearing structure can bear double-direction axial load, radial load and tilting moment. This series bearing have preload before leaving factory, no need to adjust clearance when installed. This series bearing is particularly suitable for the situation of high precision, high stiffness, low speed, and short rotate period such as rotary table, index heads and revolving milling heads. 
This kind of bearing has axial and radial running precision for your chosen. 

Rotary table bearings characteristics:
1. High precision: P4 precision, P2 precision
2. High rigidity: This series bearing have preload
3. High load:This series bearing can bear double-direction axial load, radial load and tilting moment
4. High speed: YRTS series bearing can be applied to the situation of high rotating speed


Remark:1) Comprises a connecting screw hole and the screw thread unloading hole,uniform circumference.
           2) For the 10.9 grade bolt tightening torque.
           3) The friction torque of bearings should be measured in the 5r/min speed.
           4) The fixing hole for shaft and bearing set,
           *Note the bearing fixing hole pitch and point of bisection.
           5) For long time operation and continuous operation conditions,Please be careful the reference number 
               when use.
