Non-Gear Slewing Bearing

Non-Gear Slewing Bearings are large-diameter bearings designed to support combined axial loads, radial loads, and overturning moments while allowing slow and smooth rotational movement.
Without an integrated gear, the bearing is driven by external transmission systems such as pinions, motors, or friction drives, offering greater flexibility in system design and installation.

These bearings are widely used in applications requiring high load capacity, compact structure, and precise rotational control.

Operating Conditions

• Low to medium rotational speed

• Suitable for heavy axial loads and overturning moments

• Continuous or intermittent operation

• Operating temperature typically from –20°C to +80°C (special designs available)

• Applicable for both indoor and outdoor equipment with proper sealing and lubrication

Key Advantages

• High axial and moment load carrying capacity

• Flexible drive system design due to gearless structure

• Compact structure with space-saving installation

• Smooth rotation and stable operation

• Easy maintenance and long service life

• Customizable dimensions and internal configurations

Structural Types

• Single-row ball slewing bearing (four-point contact)

• Double-row ball slewing bearing

• Crossed roller slewing bearing

• Three-row roller slewing bearing

Applications

• Cranes and lifting equipment

• Excavators and construction machinery

• Wind power equipment

• Port machinery and material handling systems

• Industrial turntables and rotary platforms

• Automation equipment and special machinery

OEM / Customization

This bearing supports OEM services and customization, allowing customers to specify brand labeling, lubrication options, precision tolerances, or packaging according to their requirements. It can be tailored to meet unique operational needs, ensuring optimal performance and full compatibility with customer-specific equipment.
