Features: axial / radial bearing YRT
YRT bearing by a thrust / radial seat, a thrust and radial shaft washer, a thrust washer, two needle keep frame component and a group of radial cylindrical roller. Seat ring and shaft ring with screw holes with uniform installation. This type of bearing with high axial and radial load capacity. High tilt stiffness and high accuracy. Suitable for rotary table, bearing chuck and cutter head configuration and measurement and experiment in. This type of bearing equipment parts to match the requirements of high. When installing the required control installation screw tightening torque.
Bearing characteristics:
1, high precision, precision can reach P4, P2;
2, high rigidity: this series of bearing with preload;
3, high bearing can bear axial load, radial load and overturning loads.
4, high speed, high speed can be applied to the work of YRTS series bearings.
Scope of application: widely used in precision rotary table indexing head, vertical grinder, hobbing machine, milling machine and other precision workpiece axis device.
