What are the different types and configurations of slewing rings available in the market?

Slewing rings are available in various types and configurations to cater to the diverse needs of different applications. The following are the different types and configurations of slewing rings commonly available in the market:

  • Single-Row Ball Slewing Rings: This type of slewing ring consists of a single row of balls placed between two rings. It offers compact design, low weight, and high load-carrying capacity. Single-row ball slewing rings are commonly used in applications where axial and radial loads need to be supported.
  • Double-Row Ball Slewing Rings: Double-row ball slewing rings have two rows of balls, providing higher load-carrying capacity compared to single-row designs. They are suitable for applications that require increased load capacity and improved stiffness.
  • Three-Row Roller Slewing Rings: Three-row roller slewing rings feature three rows of rollers arranged in a crisscross pattern. This configuration allows for higher load-carrying capacity and increased rigidity. Three-row roller slewing rings are commonly used in heavy-duty applications where significant radial, axial, and moment loads need to be supported.
  • Ball and Roller Combination Slewing Rings: In some cases, slewing rings are designed with a combination of ball and roller elements. This configuration provides a balance between load capacity and reduced friction. It offers improved rotational characteristics and is often used in applications requiring high load capacity and smooth rotation.
  • Internal Gear and External Gear Slewing Rings: Slewing rings can be equipped with internal or external gears. Internal gear slewing rings have the gear teeth on the inner ring, while external gear slewing rings have the gear teeth on the outer ring. The gear mechanism allows for controlled rotation and can be driven by external components such as motors or hydraulic systems. The choice between internal or external gear configuration depends on the specific application requirements.
  • Non-Gear Slewing Rings: Some slewing rings are designed without integrated gears. These non-gear slewing rings are often used in applications where the rotation is driven by external components or when a separate gear mechanism is already in place.
