XSU Crossed Roller Bearings

Inner Diameter: 130-874mm Outer Diameter: 205-1014mm Width: 25.4-56mm Weight: 3.3-67kg

XSU series of high rigidity cross roller bearing inner and outer rings are with the overall structure, with high rigidity, and with mounting holes, no bearing flange and installation, to a large extent simplify the installation process, and does not affect the mounting accuracy, with high precision and high torque rotation, but also free to choose the inner or outer ring rotation mode in accordance with the accuracy requirements, with greater freedom of choice. It differs XRU is sealed structure using double-sided spring reed seal, and dimensions are more compact than HGRU series, more suitable for small mounting space installed.

Bearing Features:

1. High precision: Precision level can be P4,P2

2. High rigidity: This series bearings all with preload

3. High load capacity: can bear axial,radial and tipping load

4. Small size: this kind bearing with small size can save space for machine.

Application area: precision rotation working table,manipulator rotate joints,medical machine,measuring equipments etc.
