Product Description

YRT325 YRT bearing 325x450x60mm,GCr15SiMn material,58-62 Hardness

YRT bearing

Axial/radial bearings YRT, YRTC and YRTS and axial angular contact ball bearings ZKLDF are ready-to-fit high precision bearings for high precision applications with combined loads. They can support radial loads, axial loads from both sides and tilting moments without clearance and are particularly suitable for bearing arrangements with high requirements for running accuracy.
 

Simple mounting due to fixing holes

Due to the fixing holes in the bearing rings, mounting of the units is very simple. After mounting, the bearings are radially and axially preloaded. The mounting dimensions of all series are identical.

Axial/radial bearings YRT, YRTC and YRTS

Axial/radial bearings are double direction axial bearings for screw mounting, with a radial guidance bearing. These ready-to-fit, greased units are very rigid, have high load carrying capacity and run with particularly high accuracy. They can support radial forces, axial forces from both directions and tilting moments free from clearance. The bearings are available in several series

YRT and YRTC suitable for low speeds and small operating durations

For standard applications with low speeds and small operating durations, such as indexing tables and swivel type milling heads, the most suitable bearings are series YRT and YRTC.

YRTS suitable for high speeds with low frictional torque

For the bearing arrangements of direct drive axes, there is the series YRTS. Due to their high limiting speeds and very low, uniform frictional torque across the whole speed range, these bearings are particularly suitable for combination with torque motors.

For higher running accuracy requirements, both series are also available with restricted axial and radial runout.

Axial angular contact ball bearings ZKLDF

Suitable for high speeds and long operating durations

Axial angular contact ball bearings ZKLDF are highly suitable for high speed applications with long operating duration . They are characterised by high tilting rigidity, low friction and low lubricant consumption.

How to install the YRT bearing

YRT rotary table bearing consists of a thrust / centripetal shaft ring, a thrust washer, two needle roller cage assemblies and a group of centripetal cylindrical rollers. The seat ring and shaft ring are provided with uniformly distributed screw holes for installation. However, this kind of bearing also has high requirements for matching equipment parts. The tightening torque of the mounting screws shall be controlled during installation. The following is the installation related knowledge:

1. the requirements for the matching structure are high. During transportation, the fixing screws protect the bearing parts of YRT turntable. In order to facilitate centering installation, the fixing screws can be loosened during installation. After installation, the fixing screws should be tightened again or replaced with setting screws.

2. L-section ring can be installed with or without additional support ring

3. the assembly force can only be transmitted through the installed YRT turntable bearing ring, not through the rolling element.

4. set screws shall be tightened with a torque wrench in the form of cross.

5. do not separate or exchange the bearing parts of YRT turntable for installation and disassembly.
