Combination Slewing Rings

Overview: Combination Slewing Ring Bearings

Combination slewing rings are hybrid bearings that integrate a single row of balls with cylindrical rollers. This unique structure allows for the efficient management of combined loads — including axial, radial, and tilting moment forces — with improved rigidity and rotation smoothness. The external gear design makes them ideal for equipment requiring high torque transmission and external drive integration.

Design Features

The ball-and-roller combination structure enhances load distribution and increases the bearing’s durability. External gear teeth provide straightforward meshing with pinions, simplifying installation and improving power transmission in demanding systems.

Interchangeability with ROTHEERDE

Our combination slewing bearings are dimensionally and functionally compatible with:

• ROTHEERDE

This ensures smooth upgrades, easy replacements, and reduced downtime in equipment maintenance cycles.

Typical Applications

These bearings are commonly used in applications that demand high structural rigidity and complex load handling, such as:

• Heavy-duty turntables
• Construction and mining equipment
• Material handling machinery
• Offshore and marine cranes
• Rotary drilling systems

Key Advantages

• Superior load capacity with combined rolling elements
• Reliable torque transfer via external gear teeth
• High resistance to deformation and wear
• Extended service life under harsh conditions
• Compatible with ROTHEERDE dimensions and standards

Selection Tips

When choosing a combination slewing ring, consider the following:

• Axial, radial, and moment load requirements
• Gear module and drive compatibility
• Mounting constraints and housing dimensions
• Operating environment (vibration, temperature, contaminants)

Engineered for Performance

Designed for strength and precision, our combination slewing rings deliver long-term reliability in high-load and high-impact applications. With proven ROTHEERDE interchangeability and strict quality control, they’re the ideal solution for OEMs and heavy equipment retrofits alike.
