Segmental Insights

Rolling Element Insights

Ball segment is expected to dominate the market during the forecast period. The ball segment is a crucial element within the global slewing bearing market, constituting a significant subset of the overall market. Slewing bearings, also known as turntable bearings or slewing rings, are substantial bearings engineered to handle axial, radial, and moment loads. They facilitate rotational movement between different machinery or equipment components. The ball segment in the slewing bearing market specifically refers to slewing bearings that employ ball bearings as the rolling elements. Ball segment slewing bearings provide exceptional load-carrying capacity by distributing loads across multiple ball bearings. This design efficiently supports both axial and radial loads. The raceway design of ball segment slewing bearings ensures smooth and low-friction rotation. Compared to other rolling elements like rollers or gears, ball bearings have a more compact profile. This compact design proves advantageous in applications with limited space, such as machinery operating in confined working areas. The rolling motion of the ball segment between the inner and outer raceways facilitates smoother rotation, reducing friction and wear. This characteristic is of utmost importance in applications that demand precise and continuous movement.

Gear Type Insights

External Gear segment is expected to dominate the market during the forecast period. Slewing bearings, also referred to as turntable bearings or slewing rings, play a vital role in facilitating rotational movement between different machinery or equipment components. The external gear segment of the slewing bearing market comprises bearings that incorporate external gears around the outer diameter of the bearing's ring. External gear slewing bearings offer enhanced load distribution by engaging with other components through the external gears. This design ensures even force and moment distribution, thereby improving the bearing's load-carrying capacity and efficiency. Moreover, the presence of external gears enables efficient transmission of rotational motion. By meshing these gears with a suitable driver, such as a motor or gear motor, the slewing bearing can be easily rotated, enabling precise and controlled movement. This torque transmission capability makes external gear slewing bearings suitable for applications requiring high torque, such as heavy machinery and equipment. Construction machinery, including excavators, tower cranes, and concrete pumps, extensively utilize external gear slewing bearings. The external gear mechanism enables controlled rotation, facilitating precise movement and positioning of heavy loads.
