ODM Gearless single-row ball-type swivel bearing Manufacturer, Factories

Neither the inner nor the outer ring of the swivel bearing is machined with gears. It is a smooth raceway ring. The raceway is of an arc-shaped cross-section and relies on a single row of steel balls in contact with the arc-shaped raceway at four points to bear combined loads. It can simultaneously withstand axial loads, radial loads and overturning moments. It does not directly provide rotational drive and is suitable for medium and light-duty equipment that does not require gear transmission. The structure is compact, the weight is light, the installation space requirement is small, and it is suitable for equipment that is sensitive to self-weight.

Typical applications

Specifically designed for compact and lightweight machinery that demands robust performance under complex loads without relying on traditional gear transmission systems. Ideal applications include:

Small to medium-sized cranes and excavators
Rotary conveyors and welding operation machines
Radar scanning equipment and pile drivers
Various engineering operation vehicles

This solution excels in environments where space efficiency, weight reduction, and the ability to withstand multi-directional stresses are critical—delivering reliable power transmission in a simplified, gear-free architecture.

Targeting the next generation of medium-to-light mechanical systems that prioritize compactness without compromising on load-bearing capability.

Frequently Asked Questions (FAQ)

What are the primary load-bearing advantages of this slewing bearing design?

This series features a specialized four-point contact design. This enables the configuration to simultaneously handle axial force, radial force, and overturning moments under a wide variety of comprehensive mechanical loading scenarios.

Why choose a gearless (toothless) configuration?

A gearless structure eliminates issues related to gear teeth meshing wear and operation noise. Additionally, it offers a much simpler assembly profile, requires significantly less maintenance, and is optimized for low-speed, light-load applications or installations utilizing external drive components.

How does a compact structure benefit new equipment designs?

Compared to standard multi-row roller slewing bearings, our design features a lower overall weight and requires a smaller installation volume. This plays a critical role in minimizing space requirements and promoting lightweight product development.

What typical machinery types utilize this gearless bearing?

It is ideal for applications demanding compact footprints and complex load stability, such as small-to-medium cranes, excavators, rotating conveyors, welding positioning equipment, pile drivers, radar scanners, and utility engineering vehicles.

Does this model offer high structural flexibility during rotation?

Yes. The precise distribution of internal steel balls drastically minimizes frictional resistance, which ensures highly flexible, smooth, and consistent rotational motion over extended operation periods.
