The Brief Description of THK Cross Roller Bearings:

Cross Roller Rings are used in large quantities in the ROTARY TABLES of MACHINING CENTERS, the main SPINDLE for MULTIPLE MACHINE TOOLS, and ROBOTS. Because they have a large effect on the processing accuracy of machining tools, it is important to acquire official THK products when performing maintenance or replacements.

Their rollers between the inner ring and the outer ring, the interval to intersect at right angles to each other are arranged. They can withstand the load from all directions (eg axial thrust load or momentum, etc.). Because the surface of the roller and the track into a linear contact and therefore, the bearing load and by the possibility of elastic deformation is small. This type of bearings are widely used in industrial automation, such as robots, machine tools and medical facilities, and need high rigidity, high speed close and still ensure accurate the occasion.

Features Of Cross Roller Bearings:

1. with excellent rotational accuracy

2. Installing simplifies operation

3. Bear large axial and radial loads

4.Significant savings in installation space

5. High speed capability

6. Shaft length and reduce processing costs, the geometry of thermal expansion is limited to changes .

7. Nylon spacer, low inertia, low starting torque, easy to control angle indexing

8. Optimization of preload, rigidity, high precision guide rollers running

9. Carburizing steel provides excellent impact resistance and surface abrasion resistance

10. Simple but adequate lubrication

Series of Cross Roller Bearings:

RB type ( outer split type )

RB series model for cross- Cylindrical roller bearings of the basic model , the inner and outer dimensions are the minimum possible , its structure is the outer ring is split type , the inner ring is the one designed for applications requiring high precision rotation of the inner parts .
RE-type ( inner split type )
RE series model is shaped by the XRB generated new style design , the main dimensions and XRB same type . Its structure is split inner ring is the type , the outer ring is the one designed for applications requiring high precision rotation of the outer parts .
RU -type ( inner and outer one size )
RU series models have been carried out since the mounting holes of the processing, you do not need a fixed flange and the housing . Further, since the use of external integrated with the seat ring structure mounted almost no effect on performance , it is possible to obtain stable rotation and torque accuracy . Can be used to rotate the outer ring and the inner ring .
RBC -type ( outer split type )
RBC Series models ( corresponding to the IKO's CRBC series ) whose structure is the outer ring is split type , the inner ring is integrated design , with cage full complement cylindrical roller bearings. Suitable for applications requiring high precision rotation of the inner parts .
CRBH type ( inner , outer one size )
CRBH series models , the outer ring is integrated structure for the outer ring and the inner ring rotates.
RA type ( outer split , ultra-thin )
RA Series models are the RB type , the outer ring thickness is reduced to the limit of the compact . For applications that require light weight, compact design of the site, such as robots and robotic rotating parts .
SX type ( outer split type )
SX Series Model Structure and RB series is similar to the structure of the outer ring is two divided by three snap ring connection , the inner one designed for applications that require high precision rotation of the inner place .
XRU08 type ( inside and outside the ring one size )
XSU08 series with RU series are similar, have been carried out outside the ring mounting holes of the processing, you do not need a fixed flange and the housing . Further, since the use of external integrated with the seat ring structure mounted almost no effect on performance , it is possible to obtain stable rotation and torque accuracy . Can be used to rotate the outer ring and the inner ring .
