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

Product View

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:

• High Load：The 013 series employs 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, Tilting moments.

• Internal Gear Transmission – Compact, Protected, Efficient：The defining feature of the 013 series is its 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：Heavy machinery operating environments demand extreme durability. The 013 series bearings undergo rigorous heat treatment processes.

• Rubber Seals – Keep Contaminants Out, Lubricant In： The 013 series is equipped with rubber lip seals that prevent external contaminants—dust, water, gravel—from entering the raceway cavity while retaining lubricant. This sealing extends maintenance intervals and protects the bearing’s internal components from premature wear.
