Axial/radial bearings

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

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 accuracy requirements, these bearings are also available with restricted axial and radial runout accuracy.

Axial angular contact ball bearings

Axial angular contact ball bearings ZKLDF are low-friction, ready-to-fit, pregreased bearing units with high accuracy for very high speeds, high axial and radial loads and high demands on

tilting rigidity.Axial angular contact ball bearings are particularly suitablefor precision applications involving combined loads. Their preferred areas of use are bearing arrangements in rotary tables with a main

spindle function, for example in combined milling and turning, as well as in milling, grinding and honing heads and in measurement and testing equipment.

Axial/radial bearings with angular measuring system

Axial/radial bearings with angular measuring system YRTM and YRTSM correspond in mechanical terms to series YRT and YRTS, but are additionally fitted with an angular measuring system. The measuring system can measure angles to an accuracy of a few angular seconds by non-contact, magneto-resistive means.

Further information on axial/radial bearings with absolute value angular measuring systems YRTMA and YRTSMA can be found in special publication SSD 30.
 

Features 

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.

Due to the fixing holes in the bearing rings, the units are very easy to fit.

The bearings are radially and axially preloaded after fitting.

The mounting dimensions of all series are identical.

Axial/radial bearings YRT in the size range of d = 580 mm to d = 1 030 mm have been replaced by YRTC.

Compared with the predecessor product YRT, these bearings have higher rigidity, a higher limiting speed and lower bearing friction.

With angular measuring system 

Axial/radial bearings are also available with an absolute value angular measuring system or have systems with pitch-coded reference marks. The measuring systems can measure angles to an accuracy of a few angular seconds by non-contact means.

Areas of application For standard applications with low speeds and small operatingdurations, such as indexing tables and swivel type milling heads, the most suitable bearings are generally series YRT and YRTC.

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 accuracy requirements, these bearings are also available with restricted axial and radial runout accuracy.

Axial angular contact ball bearings ZKLDF are particularly suitable for high speed applications with long operating duration.

They are characterised by high tilting rigidity, low friction and low lubricant consumption.
 

Installation Instructions

 

1. Bearing installation diagram

1.1 Design & Installation 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.

1.2 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.

1.3 Mounting forces must only be applied to the bearing ring to be fitted, never through the rolling elements.Tighten the fixing screws in crosswise using a torque wrench (shown in figure 2).

1.4 Don't separate or interchanged bearing components during fitting and dismantling.

1.5 Starting friction torque can be 3 to 3.5 times as high as the value of friction torque in the dimension tables.

 

2. Bearing Lubrication Maintenance

YRT Rotary Table bearing use German high quality grease for lubrication, standard oil filling

holes are made on the bearing, lubrication maintenance points are as follows:

2.1 Grease:LUBCON Turmogrease Li 802 EP (Made in German)

2.2 Grease maintenance cycletime: 3-5 months;

2.3 Check the situation of bearing grease regularly, ensure an clean environment to prevent

contaminants from entering the bearing;

2.4 Fill the grease by oil guns or other tools through the oil holes location as shown below:
