The single-row ball slewing bearing is a bearing product specially designed for slewing motion, with a single row of steel balls as rolling elements. Its raceways are specially designed to enable the steel balls to form two-point or four-point contact with the raceways, thereby achieving the capacity to withstand multi-directional loads. 

The inner and outer rings usually adopt a split design (one integral ring and one split ring) for easy steel ball installation; integral designs are also available but less common. The steel balls are high-precision ones with a single row and equal diameter, combined with advanced heat treatment technology. They exhibit excellent performance in withstanding axial and radial loads, and can easily cope with various complex working conditions. 

There are two main types of raceway shapes:

Four-point contact ball type: It adopts a Gothic arch raceway, which is the most common and representative single-row ball slewing bearing. The steel balls form four-point contact with this type of raceway in all directions. 

Two-point angular contact type: The raceway cross-section is arc-shaped, and the steel balls form two-point contact with the raceway at a certain contact angle (e.g., 45°). It is mainly used in situations where combined loads are borne with axial loads as the primary component. 

The precisely machined ball raceway design ensures an extremely low friction coefficient during bearing operation, making the slewing process smoother and more flexible, and effectively reducing energy consumption. Manufactured from high-wear-resistant materials, this bearing can maintain excellent performance and a long service life even under high-load and long-term operating conditions. 

To adapt to different operating environments, the single-row ball slewing bearing offers a variety of sealing solutions, which can ensure its performance under various working conditions and effectively prevent the intrusion of dust and moisture.
