Ball Slewing Rings with flang rings:
*Single row design with four point raceway geometry
*Untoothed rings with flange thicknesses of 12 and 21mm
*Ball diameters 20 to 32mm
*Raceway diameters of 311 to 1091mm or 955 to 1455mm
*For applications with light loads
*Enables lightweight structures in spite of large bearing diameter
*Applications: Handling technology,manlift platforms,turntables
Roller/Ball Combination Slewing Rings:
*Roller raceway to take up the axial loads
*Ball raceway provides support for radial loads
*Ball dia. 25 to 70mm,roller dia. Up to 100mm
*Used in application with a dominant axial force & low radial load/tilting moments
*Standard series with outside diameters up to 5500mm
*Typical applications:Bulk materials handling;Stacker reclaimers;Bucket wheel excavators,machine tools
Ball Slewing Rings:
*Single row and double row design
*Ball diameters 12 to 70mm
*Four-point raceway geometry
*Optional preloaded raceway system and centerings
*Enables robust designs for arduous application conditions
High resistance to "false brinelling" in heavy vibration conditions
*Reduced sensitivity to shape deformations in the mounting structure
*Higher static load capacity than similar design Cross Roller Rings
*Outside diameters from 180 to 3000mm
*Often designed as special versions according to customer requirements,outside diameter up to 5200mm
*Frequently used in wind energy turbines;cranes;construction machinery,mechanical engineering and special purpose machinery
Double Axial Slewing Ring:
*Double row design with large supporting balls and smaller retaining balls
*Frequently replaced by double row ball slewing rings in new design
*Used in cranes and as replacement parts for existing equipment
*Standard series with outside diameters up to 5200mm
*Both raceways in two point geometry
*Special designs can be supplied
*Ball diameters 20 to 70mm
Cross Roller Slewing Rings:
*Single row roller raceway under 45 degree
*Roller diameters 12 to 60mm
*Alternately arranged rolling elements
*Constant friction torque with different loads
*Higher dynamic service life than similar Ball Slewing Rings design
*High demands on the rigidity and precision of the mounting structure in comparision with Ball Slewing Rings
*Applications: Robots,antennas, medical technology, positioning devices, machine tools
*Can be supplied to special customer requirements
Roller Slewing Rings:
*Triple Row Roller Slewing Rings
*Roller diameters 10 to 100 mm
*Plastic,steel or brass cage segments according to loads
*Designed to provide the combination of the highest capacity in the smallest configuration.
*Greater static and dynamic load capacity,higher rigidity and constant friction torque compared with all other Slewing Ring designs (with the same raceway diameter)
*High requirements on the rigidity and precision of the mounting structure
*Standard series with outside diameters from 1400 to 5200mm
*Mostly supplied as customer specific designs.
