High precision Rotary Table Bearing YRT260 Turntable bearing YRT260

Rotary Table Bearing sepecification

Series Introduction

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 p reload,

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.

Design & Installation
Retaining screws secure the bearing components during transport. For installing the bearing easier, the screws should be loosened before fitting, and secured again or replaced by positioning screws after fitting.
The L-section ring can be fitted with unsupported or supported ring.
a) Without supported ring, the bearing type is YRT.
b) With supported ring, the bearing type is YRT…VSP.And the whole surface of L-section should be supported.
Mounting forces must only be applied to the bearing ring to be fitted, never through the rolling elements.
Don’t separate or interchanged bearing components during fitting and dismantling.
Starting friction torque can be 3 to 3.5 times as high as the value of friction torque in the dimension tables.
