XU080120 69*170*30mm crossed roller bearing

XU080120 69*170*30mm crossed roller bearing

XU series crossed roller bearings structure:

1.crossed roller bearing without gear teeth

2.cylindrical rollers to DIN 5402, spacers made from plastic

3.lubrication nipple on the circumference of the outer ring

4.rolling element pitch circle diameter

5.from 77 mm to 515 mm

Design solution

The bearing arrangements of the carousel and containers are

based on a four point contact bearing of series VLU 20.

The slewing ring is designed such that the three bearing

positions in the machine can be fitted with the same bearing.

The bearing arrangement:

■ allows the required centre clearance

■ allows high circumferential speeds (3,5 m/s)

■ is easy to fit and cost-effective.

The bearings can support axial, radial and tilting moment

loads and the bearings on the containers can also support

the resulting centrifugal forces. The maximum operating

temperature is +140 °C.

The particular features of the bearings are:

■ ground raceways

■ guidance of the rolling elements by a brass strip cage

■ optimised surface quality in the bearing gap

■ lubrication with lithium complex grease

■ FPM seals resistant to high temperatures.

Features

Crossed roller bearings

■ are units comprising outer rings, inner rings,

rolling elements (cylindrical rollers) and spacers

– depending on the series, the inner ring or outer ring is

unsplit or is split in a circumferential direction

■ can, due to the X arrangement of the rolling elements,

support axial loads from both directions as well as radial

loads, tilting moment loads and any combination of loads

by means of a single bearing position

– this allows designs with two bearing positions to be

reduced to a single bearing position

■ have high rigidity and very high running accuracy

■ are preloaded and, with grease lubrication, are suitable

for circumferential speeds up to

– 2 m/s (n · DM = 38 200)

■ are greased but can alternatively be lubricated with oil

■ are particularly easy to fit

■ are also available in a corrosion-resistant design with the

INA special plating Corrotect?.

Crossed roller bearings SX

■ have standard clearance or are preloaded

■ are located in the adjacent construction by means of

clamping rings

■ are suitable, with standard clearance, for circumferential

speeds:

– with oil lubrication up to 8 m/s (n · DM = 152 800)

– with grease lubrication up to 4 m/s (n · DM = 76 400)

■ are preloaded and suitable, with oil lubrication,

for circumferential speeds up to

– 4 m/s (n · DM = 76 400).

Crossed roller bearings XSU

■ are preloaded

■ are screw mounted by means of the bearing rings directly

to the adjacent construction.

Crossed roller bearings XV

■ are screw mounted by means of the outer ring to the

adjacent construction

– the inner ring is located by means of a locknut

■ can be adjusted very precisely to give a specific clearance

or preload by means of the locknut.

We can produce percision crossed roller bearings and YRT rotary table bearings as THK/INA/IKO quality,which percision grade reach to P4/P2.
