YRT bearings (rotary table bearings) are axial and radial combined cylindrical roller bearings, including two thrust needle roller bearings and a radial cylindrical roller bearing with the combination of axial and radial PRELOAD. For the convenience of transportation and fixing, two or three symmetrical screws are fastened to the two rings in order to prevent rollers and rings generating collisions which influence bearing accuracy.

Feature of Rotary Table Bearing
1. High axial and radial load capacity.
2. High tilted rigidity:YRT series bearings are with preload and high precision:Precision at P4, P2.
3. Radially and axially preloaded after fitting.
4. High load capacity: Bearings can support axial load, radial load and tilting load.
5.High speed: YRTS series bearings can be applied in the high speed working condition.
