A. Product Description

YRT325 Rotary table bearing (325x450x60mm) Replace Germany Turntable bearing

YRT325 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.

E. Installation

Design & Installation for YRT325 Rotary Table Bearing :

Structure with the requirements shown in Figure 1

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 YRT rotary table bearing ring to be fitted, never through the rolling elements.

Tighten the fixing screws in crosswise using a torque wrench (shown in Figure 2).

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.
