Heavy Duty 013 Internal Gear Cross Roller Slewing Bearing for Industrial Robots Rotating Machinery

Product View

Moreover, slewing bearings are large-diameter rotational bearings designed to support heavy loads while enabling 360° movement. Within this category, the 013 series stands out for its internal gear configuration: the driving pinion gear meshes with teeth cut into the inner ring, eliminating the need for an external gear ring and creating a more compact, contamination-resistant package.

Key Features

In addition, Key Features of the 013 series are designed to support demanding heavy-duty motion systems.

High Load Capacity

This series delivers a four-point contact ball geometry where the balls contact the raceways at four distinct points. This configuration allows a single bearing to simultaneously support axial loads, radial loads, and tilting moments.

Internal Gear Transmission – Compact, Protected, Efficient

Moreover, this design integrates internal gear teeth machined directly onto the inner ring. When the driving pinion gear meshes with these inner teeth, it drives the inner ring to rotate, achieving efficient torque transmission.

Heat-Treated for Maximum Durability

Therefore, this structure ensures high resistance under heavy machinery operating environments. The 013 series bearings undergo rigorous heat treatment processes to improve strength and extend service life.

Rubber Seals – Keep Contaminants Out, Lubricant In

In addition, this design includes rubber lip seals that prevent external contaminants such as dust, water, and gravel from entering the raceway cavity while retaining lubricant. This extends maintenance intervals and improves operational reliability.

Applications

Therefore, typical applications include industries where heavy rotation and structural stability are required:

• Excavators and Construction Equipment
• Cranes and Derricks
• Wind Turbines (Yaw and Pitch Systems)
• Medical Scanners (CT/MRI/Robotic Surgery)
• Solar Trackers
• Industrial Turntables and Rotary Indexers
• Radar and Antenna Positioning Systems
• Mining Equipment
• Robotics and Automation
