Single-row Ball Slewing Bearing without Gear

Single-row ball slewing bearing without gear

Single-row ball slewing bearing without gear is an oversized bearing capable of simultaneously supporting massive axial loads, radial loads, and tilting moments. Unlike standard bearings, it does not have built-in gears. Instead, it relies on external drive mechanisms (such as motors or gear reducers) to achieve rotation. Toothless slewing bearings are indispensable core components in modern industrial equipment, and their performance  directly relates to the overall stability and reliability of the machinery.

Features & performance advantages

High load capacity: capable of handling axial, radial and overturning moment loads simutaneously, offering a highly compact structure;

High precision and rigidity: precision machining ensures positioning accuracy and stability during rotation.

Excellent sealing: equipped with high-performance seals that effectively prevent dust, water, and other contaminants from entering, thereby extending service life.

Easy maintenance: typically features a centralized lubrication design for convenient upkeep.

FAQ

1. How to choose a slewing bearing without gear?

When selecting a model, we need to pay attention to several key parameters: a, model/specifications: usually includes inner diameter, outer diameter and height information; b, load capacity: includes static load and dynamic load, selection should be based on actual working conditions; c, precision grade: affects rotational accuracy, common grades include standard and high precision; d, structural form: common types include single-row four-point contact ball bearings and single-row crossed roller bearings, suitable for different load combinations.

2. What should be noticed when we receive the slewing bearings?

For harsh environments with high temperatures, high humidity, or heavy dust, special sealing and materials must be selected. During installation, the flatness and parallelism of the mounting surface, as well as the bolt pre-tightening force, are critical to performance and lifespan. And it is also important to choose the right grease and replenishing it regularly to ensuring a long service life.
