Features:
YRT precision rotary table bearing is a kind of bearing fixed by a
bidirectional thrust bearing and a centripetal-guided bearing. They
can support radial loads, axial loads from both directions and
tilting moments free from clearance and are particularly suitable
for bearing arrangements with high requirements for running
accuracy,like rotary tables, millings heads and reversible
clamps.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.
Sealing/Lubricant:
YRT bearings are supplied with seals. YRT bearings are greased by a
lithium complex soap grease and can be lubricated via the outer
ring and L-section ring.
Operating temperature:
YRT bearings are suitable for operating temperatures from 30℃ to
120℃
Design and safety guidelines:
Basic rating life:
Please contact us in relation to checking of the basic rating life
.The speed ,load and operating duration must be given.
Static load safety factor:
The static load safety factor S0 indicates the security against
impermissible permanent deformations in the bearing. It is
determined as follows:
Static load safety factor :Cor Coa N
Basic static load rating according to dimension tables: For Foa N
Maximum static load on the radial or axial bearing.
Caution! In machine tools and similar areas of application, S0
should be >4
Limiting speeds:
The bearings allow the limiting speeds given in the dimension
tables. The operating temperatures occurring are heavily dependent
on the environmental conditions. Calculation is possible by means
of a thermal balance analysis based on frictional torque data.
Frictional torque:
The bearing frictional torque MRL is influenced primarily by the
viscosity and quantity of the lubricant and the bearing preload.
The lubricant viscosity and quantity are dependent on the lubricant
grade and operating temperature. The bearing preload is dependent
on the mounting fits, the geometrical accuracy of the adjacent
parts, the temperature difference between the inner and outer ring,
the screw tightening torque and the mounting situation.
Starting torque:
For YRT bearing, it must be taken into consideration that the
frictional torque can increase by a factor of between 2 and 2.5
with increasing speed.
Accuracy of adjacent construction:
The adjacent construction should be produced in accordance with
Figure and the tolerances must be in accordance with the tables
starting on page. Any deviations will influence the bearing
frictional torque ,running accuracy and running characteristics.
Legend to Figure:
1.Support over whole bearing height. It must be ensured that the
means of support has adequate rigidity.
2.A precise fit is only necessary if radial support due to the load
or a precise bearing position is required.
3.Note the bearing diameter D1 according to the dimension tables.
Ensure that there is sufficient distance between the rotating
bearing rings and the adjacent construction.

Mounting dimensions H1,H2
L-section ring without support ring:
For the case “L-section ring without support ring”, the bearing
designation is :YRT
L-section ring with support ring:YRT bore diameter VSP
For the case “L-section ring with support ring”, the bearing
designation is :YRT VSP
Caution! For bearing arrangements with a supported L-section ring ,
only bearings with the suffix VSP,EB or T52EA can be ordered. If
the normal design is mounted with a supported L-section ring, there
will be a considerable increase in the bearing frictional torque
.The support ring should be at least twice as the shaft locating
washer of the bearing.
Fitting:
Retaining screws secure the bearing components during transport,
For easier centring of the bearing ,the screws should be loosened
before fitting and either secured again or removed after fitting.
Tighten the fixing screws in crosswise sequence by using a torque
wrench in three stages to the specified tightening torque MA,
rotating the bearing:
Stage 1 40% of MA
Stage 2 70% of MA
Stage 3 100% of MA
Observe the correct grade of the fixing screws.
Caution! Mounting forces must only be applied to the bearing ring
to be fitted, never through the rolling elements. Bearing
components must not be separated or interchanged during fitting and
dismantling. If the bearing is unusually difficult to move ,loosen
the fixing screws and tighten them again in steps with a crosswise
sequence. This will eliminate any distortion. Bearings should only
be fitted in accordance with ,Fitting and Maintenance Manual.
