XU Series Crossed Roller Bearings

This model can be used for both inner-ring rotation and outer-ring rotation. XU Series Crossed Roller Bearings (Integrated Inner/Outer Ring Type, both for inner-ring rotation and outer-ring rotation) Since the mounting holes are provided, this model does not require a presser flange or housing. In addition, because it has an integrated inner/outer ring structure and is equipped with washers, its performance is minimally affected by the mounting procedure, ensuring stable rotation accuracy and torque.

Advantage of XU crossed roller slew bearings.

1. Crossed roller bearings can withstand radial and axial loads at the same time. One bearing equals 2 standard bearings.

2. Rollers of crossed roller bearings are in line contact with the raceway, while steel balls of the ball slewing bearings are in point contact with the raceway, so cross roller bearings have higher loading capacity and stiffness.

3. Cross roller bearings have low grease consumption due to high rotation efficiency and low heat dissipation, so their maintenance interval is longer.

4. Provide extremely high rotation accuracy, negative clearance available.
