Roller/Ball Combination Slewing Rings

Roller raceway to take up the axial loads

Ball raceway provides support for radial loads .All parts are retained together as a unit during fitting.

Ball diameters 25 to 70 /0.984 to 2.756 in.roller diamaters up to 100mm/3.937 in

Used in applications with a dominant axial force and low radial load/ titing moments.

Frequently produced as special designs according to customer requirements

Combined roller and ball bearings are designed as standard with a roller raceway (supporting raceway) and a ball raceway (retaining raceway). This makes this type of design particularly suitable for high axial loads and harsh environmental conditions.Typical applications Bulk material handling stacker reclaimers bucket wheel excavators machine tools.

All of our slewing bearings can be manufactured with internal gears, external gears or without gearing. Special gearing, such as helical and worm gears, are also available upon request. The seal concept is also configured for each individual case of use, and takes account of particular environmental conditions, such as particularly sausty air. The bearings can also be coated for extra corrosion protection.
