XRU/XRUS series cross roller bearing
Description
XRU series (mounting hole, high rigidity) cross roller bearing (instead of THK RU series; IKO CRBF series)
Due to the integral structure of the inner and outer rings, the XRU series of high-rigidity cross-roller bearings have high rigidity and mounting holes. They do not require fixing flanges and housings during installation, which greatly simplifies the installation procedure and does not affect the installation accuracy. It has high rotation precision and large torque, and can also freely select the inner ring or outer ring rotation according to the accuracy requirement, and has a large degree of freedom of selection.

XRSU series cross roller bearing (instead of INA company XSU08 series)
The XRSU series of high-rigidity cross-roller bearings have a high-rigidity and a mounting hole for the inner and outer rings. They do not require fixing flanges and housings during installation, which greatly simplifies the installation process and does not affect the installation accuracy. It has high rotation precision and large torque, and can also freely select the inner ring or outer ring rotation according to the accuracy requirement, and has a large degree of freedom of selection. The difference between it and the XRU is that the sealing structure uses a double-sided spring reed seal and is more compact than the XRU series, making it suitable for installations with small installation space.
