As a leading professional manufacturer of rotary bearings, we offer our high-precision Single Row Four-Point Contact Ball Slewing Bearings, designed to deliver exceptional performance in demanding rotational applications. This bearing type features an optimized internal geometry where each ball maintains four distinct points of contact with the raceways. This unique design enables the bearing to simultaneously handle significant axial loads, radial loads, and high tilting moments with a single bearing unit, simplifying the overall structure of your machinery.

The raceways are precision-ground and induction-hardened to ensure smooth operation, durability, and consistent rotational accuracy. We utilize high-grade alloy steel and precision-engineered ball separators or spacers to minimize friction, reduce wear, and ensure reliable performance even under fluctuating loads.

Key characteristics include:

• High Load Capacity: Capable of supporting combined loads (axial, radial, and moment) in a compact design.

• Space and Cost Efficiency: Eliminates the need for multiple bearing arrangements, simplifying installation and reducing system complexity.

• Smooth Operation: Ensures low friction torque and consistent motion, suitable for both low-speed, heavy-load oscillations and continuous rotation.

• Versatility: Available with internal or external gearing options, as well as non-geared versions. Custom sealing solutions are available to protect against contamination in harsh environments.

Typical applications include small to medium-sized excavators, crane turntables, aerial platforms, wind turbine drives, industrial robots, medical equipment (CT scanners), and solar tracking systems. Backed by strict quality control and advanced manufacturing processes, our Single Row Four-Point Contact Ball Slewing Bearings provide the durability and reliability required for long-term service in critical operations.
