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.
