A single bearing can simultaneously support thrust load, radial load, and moment.
- Since the gears are directly processed on either the outer ring or the inner ring, the structure of the turning part can be simplified. - Holes for bearing mounting or tapped holes are processed in the outer and inner rings, making it easy to assemble and disassemble the bearings. - It can accommodate large sizes, allowing for safe turning motion under greater loads with low torque. - It is available for made-to-order production, enabling the use of custom turning bearings that match specific designs and specifications.

Applications/Examples of results
■Examples of Swivel Bearings Swivel bearings suitable for their applications are widely used in the swivel parts of various construction and civil engineering machinery such as power shovels and tower cranes, as well as in cargo handling machinery like truck cranes and industrial machines including robots. For vertical (horizontal axis) use or high-speed rotation requirements, we accommodate by changing to designs with retainers. Recently, there have also been many cases of swivel bearings being used in precision machinery fields such as medical equipment like C.T. scanners and machine tools like grinding machines. ■Information on Swivel Bearings (Manufacturing Range and Designation Structure) Since swivel bearings are not standardized, we generally design and manufacture products tailored to each specific application. ● We will select the optimal swivel bearing that meets your usage conditions. ● We design and manufacture swivel bearings according to special usage conditions and specification requirements. ● We can produce replacement products (substitutes or equivalents) for swivel bearings from other manufacturers that you are currently using. ● We also provide repair and overhaul services for swivel bearings. (※ We can accommodate products from other manufacturers as well.)
