IMO Slewing Rings For Construction

IMO Slewing Rings have been impressing the construction machine sector for more than 25 years with their robustness, long service life and reliability. 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.


What construction machines are IMO Slewing Rings typically used for?

  • Excavator attachments
  • Wheel loader
  • Asphalt vibratory rollers
  • Landfill compactors
  • Drilling rigs


Cost-effective and tried-and-tested, IMO Slewing Rings 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


For companies operating in the construction industry, IMO Slewing Rings provide a variety of benefits including:
