Diameter from 370 mm to 6300 mm. Hardend or un- hardend gear. Raceway diameter from 310 mm to 1455 mm, nor- mal or double holes. Pre- load or precision class on demand. Four-point-contact raceway construction, for normal low-cost applications without high requirement of load or quality on demand. Light series, flange bearings with internal- or external gear or without gear ( L-se- ries). Four-point-contact ball bea- rings, single row, without gear, with internal or external gear are the most used series (01 series). Higher static adequate load capacity than constructed in the same way as cross rollers slewing bearings. Preload, clearance precision class, special cage or seal, hardend gear etc. are mostly required by customers for this serie. This series require the highest technical and technological know-how by the manufacture. Also the certificate like GL, DNV or ABS is mostly required. For heavy load applications is this serie especial suitab- le (02 series) like excava- tors, cranes and wind ener- gy equipments. Slewing rings for heavy machines, pitch or blade bearings for the wind energy plants are mostly used with this series. Insensible against deviation of the connected construc- tion. Normal double-row ball bearings, diameter from 500 mm to 4500 mm. With special seal, double seal system, with special cage or lubrication system are our standard programme. Constant rotational resistance at different load and higher dynamic life than identical ball slewing rings. Higher demands on the stiffness and the accuracy of the fixture in relation to the ball slewing bearings are fullfilled. High requirements to the stiffness and the correctness of the connecting construc- tion parts comparing with all other forms of slewing rings. Cross-roller slewing rings with single-row raceway. Roller diameter from 8 mm to 80 mm. Bearing diameter up to 5000 mm. Besides synthetic spacer, also cage from synthal, steel, viton, brass are available. The special seal and surface system like zinc plating, painting can ensure special applications for off-shore. At the same time fullfilling high requirements to the stiffness and correctness of the installation construction. High dynamic load. High stiff- ness and even pre-set potentiometer according to all other slewing rings configuration (by the same raceway diameter). Triple-row roller slewing rings can be used in heavy load requirements with tight required space. Diameter up to 5000 mm. With normal, viton or steel seal, with plastic spacer, plastic cage, steel cage, brass cage or special cage, with normal quality class, or precision, preload are our standard supply programme.
