Slewing Bearing

Slewing Bearings are used in the swiveling areas of various type of machineries, e.g.

Futures of Slewing Bearing

A slewing bearing can receive thrust loads, radial loads, and moments at the same time.

Type of load

Axial Load (Fa )
The load applied perpendicularly to the bearing is the total weight of the upper rotating body, the weight of the lifted object, the balance weight, etc.

Radial Load (Fr )
Load applied horizontally to the bearing, such as gear meshing force, wind pressure, inertia of the upper body, etc.

Moment/Tilting Torque(M )
Total load obtained by integrating the distance between the point of application of Fa and Fr and the center of the bearing shaft on Fa and Fr, respectively.

*Depending on the usage, it is necessary to take into account the load coefficient (impact coefficient).

Gears are machined directly on either the outer ring or the inner ring, simplifying the structure of the rotating part.
Through-holes or tapped holes for bearing installation are machined in the outer ring and inner ring, making it easy to assemble and remove the bearing.
Since it is compatible with large sizes, it is possible to obtain reliable turning motion with low torque even with larger loads.
We can manufacture to order, so you can use your own slewing bearing to suit your design and specifications.
