Cross Roller Bearings

The crossed roller bearing is a special type of bearing in which the inner ring is split and the outer ring rotates. Since the separated inner ring or outer ring is equipped with rollers and spacer rings, which are fixed together with the cross roller ring to prevent separation from each other, it is easy to install the cross roller bearing. Since the rollers are arranged in a cross, only one set of crossed roller bearings can bear loads in all directions.

Compared with standard bearings, the rigidity is increased by 3 to 4 times. At the same time, because the inner ring or outer ring of the crossed roller bearing is a separate structure, the bearing gap can be adjusted, and even if the preload is applied, high-precision rotational movement can be obtained. Moreover, due to its special structure, it is usually used as an articulated bearing in industrial robots.

QXV Series

The XV type is designed with mounting holes in the outer ring and splited inner ring, since it has mounting holes on the outer ring, flanges and housing are not required when installing. In addition, because of the integrated outer ring, the installation has almost no effect on performance, so stable rotation accuracy, torque and rigidity can be obtained, it is mostly used in applications where the outer ring rotates, such as industrial robot joints, special robots, CNC multi-axis turntables, and rotating Tool magazine, industrial turntable, counterpoint platform, radar communication equipment, etc.

QSX Series

QSX series with the similar structure to RB series, the outer ring is a two-part structure, connected by three spring snap rings, and the inner ring is designed in one piece, which is suitable for places that require high rotation accuracy of the inner ring.

QRU Series

The RU type is designed by integrated inner and outer rings with mounting holes, flange and housing not required, easy to install. In addition, installation has almost no effect on performance, so stable rotation accuracy and torque can be obtained.
It can be used for outer ring and inner ring rotation.

QRAU Series

The RAU type is designed by integrated inner and outer ring.
Since its cross-section is very small, the device's lighter and smaller could be achieved. For its integrated structure of inner and outer rings, it can be used for outer ring rotation and inner ring rotation. There are also 5mm width thin compatible with RA type. The ultra-thin product line is available from an small inner diameter of 10mm.

QRB&CRBC Series

The RB type is designed by split outer ring and rotation inner ring.
This model is the basic cross-roller bearing, it with a divided outer ring and an inner ring which integrated with the main body. It is most suitable for the parts that require the rotation accuracy of the inner ring.
For example, it can be used for the rotating part of the indexing table of a machine tool.

QRE Series

The RE type is designed by split inner ring and rotation outer ring.

Its main dimensions are the same as the RB type. It is most used where requires a rotation accuracy on outer ring.

QRA Series

The RA type is designed by split outer ring and rotation inner ring.
This model is a compact type that reduces the thickness of the inner and outer rings of the RB type to the limit.
Lightweight and miniaturized designs can be realized for products such as robots and manipulator rotating parts.
