The single row four point contact ball slewing bearing is composed of two seat rings, which design in compact structure and light weight, steel ball contact with the circular raceway at four point, it can bear the axial force, radial force and the tilting moment at the same time.
It can be used for slewing conveyer,welding manipulator, light & medium duty crane, excavator, and other construction machinery.
Slewing ring bearings are comprised of two rings, each of which contains a precision raceway that is induction hardened on the surface to a specified depth. Each ring is made from a medium carbon steel forging.Â
Mounting holes are generally spaced around the faces of the inner and outer ring along a uniform bolt circle and equal spacing. These holes can be thru holes, tapped holes, blind tapped holes, counter-bored holes, etc. Sometimes bolt circle or spacing requirements need to be customized to meet the demands of a specific application, in which case custom options are available. In the case of either the standard part numbers listed in this catalog, or other custom versions provided the equipment designer, manufacturer, or user is responsible to determine that the mounting design is adequate.
Slewing ring bearings can be supplied as ungeared, or with gears on either the ID of the inner ring or the OD of the outer ring. Gears are typically a standard stub involute spur gear with backlash provisions and AGMA Q8 quality minimum.
Details for each bearing can be found in the enclosed dimensional tables, and drawings are available. Custom gear configurations are also available.
At least one grease fitting is included in one of the rings. The quantity may increase with the diameter of the bearing. For bearings with gears, the grease fitting(s) are located on either the ID or OD of the ungeared ring. For ungeared bearings,come equipped to accommodate grease fittings on either the inner or outer ring. Custom quantities, locations and configurations for grease fittings are available.
