External Gear Slewing Bearing
External Gear Slewing Bearings integrate a slewing ring bearing with an externally machined gear, enabling simultaneous load support and rotational drive. By combining bearing and gear functions into one compact unit, these bearings simplify system design, reduce installation space, and improve transmission efficiency. They are widely used in rotating structures requiring smooth motion, precise positioning, and reliable torque transmission.
Designed to withstand combined axial loads, radial loads, and overturning moments
Suitable for low to medium rotational speeds
Operates reliably under heavy loads, shock loads, and continuous-duty conditions
Compatible with grease or oil lubrication systems
Performs well in harsh environments such as dust, vibration, and outdoor exposure
Integrated external gear design eliminates the need for separate ring gears
High load-carrying capacity with excellent moment resistance
Compact structure reduces overall system weight and installation complexity
Smooth rotation with stable torque transmission
Easy mounting and maintenance, suitable for large-diameter applications
Single-row ball slewing bearing with external gear
Double-row ball slewing bearing with external gear
Three-row roller slewing bearing with external gear
Customized designs available for specific load and precision requirements
Construction machinery (cranes, excavators, aerial work platforms)
Port and material handling equipment
Wind power yaw and pitch systems
Industrial turntables and rotary platforms
Metallurgy, mining, and heavy-duty machinery
Automation and positioning systems
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.
