Description

Features: Axial/Radial Bearing YRT

YRT bearings consist of a Thrust/central ring, a Thrust/central shaft collar, a Thrust washer, two A needle roller cage assembly and a set of centripetal cylindrical rollers. The seat ring and collar have uniform mounting screw holes. This type of bearing has high axial and Radial load carrying capacity. High tilt stiffness and extremely high precision. Suitable for rotary tables, chucks and milling heads, as well as bearing configurations for measurement and experimentation. This type of bearing also has higher requirements for matching equipment parts. The tightening torque of the mounting screws must be controlled during installation.

Bearing Features:

1. High precision: Accuracy can reach P4 and P2 levels;

2. High rigidity: The bearings are preloaded ;

3, high load: can withstand axial load, Radial load, Overturn load.

4, high speed: YRTS series bearings can be used in high-speed work.

Scope of application: It is widely used in precision rotary table vertical grinding machines, indexing heads, gear hobbing machines, milling machine workpiece axes and other precision devices.
