Cross Roller Slewing Ring Bearing

What Are Cross Roller Slewing Ring Bearings?

Cross roller slewing bearings feature a single row of cylindrical rollers arranged at right angles to one another, alternating in orientation. This crossed-roller configuration enables the bearing to support axial, radial, and moment loads simultaneously, making it ideal for high-precision and high-rigidity applications.

Gear Configurations

To accommodate various drive systems and design constraints, our cross roller slewing bearings are available in the following types:

• Internal Gear: Offers protection and a compact design for enclosed mechanisms.
• External Gear: Simplifies integration into open drive systems with easy access.
• Without Gear: Ideal for friction drives or custom transmission solutions.

Interchangeable With Leading Brands

Our slewing ring bearings are dimensionally and functionally compatible with global brands, ensuring easy replacement and system integration:

• KAYDON
• Schaeffler (INA)
• SKF
• ROTEK
• ROTHEERDE
• ROLLIX

Typical Applications

Designed for both rotational precision and load support, cross roller slewing bearings are used in:

• Machine tool indexing heads
• Industrial automation equipment
• Radar and satellite antennas
• Medical equipment (e.g., CT scanners)
• Robotic joints and positioning systems

Advantages of Cross Roller Design

• Handles combined loads with excellent rigidity
• Compact profile reduces space requirements
• Low rotational torque for smooth, precise movement
• High stiffness with minimal deflection under heavy loads
• Available in gear or gearless variants for design flexibility

Selection Considerations

When selecting the right slewing ring bearing, take into account:

• Expected load types (axial, radial, moment)
• Gear compatibility and drive system requirements
• Mounting space and structural integration
• Operating environment (cleanroom, outdoor, high vibration)
