Crossed-Roller Slewing Ring Bearings

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
