Description

Slewing rings are large diameter antifriction bearings for the simultaneous transmission of axial and radial forces as well as tilting moments. They replace traditional solutions with fixed and floating bearings as well as king pin bearings. Frequently, this results in bearings with axial/radial bearing combinations with one bearing point. This can significantly simplify the design of the mounting structure and the installation of the bearings, which in turn reduces effort and costs. Cost-effective, tried-and-tested IMO antifriction bearings are available as: Ball slewing rings, roller slewing rings, and ball-roller combination slewing rings Four-point bearings, double four-point bearings/eight-point bearings, flange bearings, wire race bearings, cross roller bearings Segmented slewing rings Gear rims External gearing, internal gearing, or without gearing Diameter ranging from 100 mm to 6000 mm With cages (steel, brass, or plastic) or spacers (brass or plastic) With standard seals or specially produced special seals Optionally with induction-hardened raceways Different corrosion protection coatings possible IMO slewing rings have mounting holes and a sealed raceway system with grease lubrication. They can be combined with motors, pinions, and planetary gears. Functions and parts of the mounting structure - such as attached bearing rings - can be integrated. Catalog standard parts or tailored slewing rings IMO slewing rings are available as a large selection of standard series. However, the special capabilities of our engineers lie in the development of special custom designs for our customers.
