Collection: IMO Slewing Rings

Neilson Hydraulics are a UK distributor for IMO Slewing Rings and Slew Drives.

Slewing Rings, are also known as large diameter antifriction bearings for the simultaneous transmission of axial and radial forces, as well as tilting moments. They serve as replacements for traditional solutions with fixed and floating bearings, as well as king pin bearings. Often, this results in bearings with axial/radial bearing combinations with one bearing point. This can streamline the design of the mounting structure and the installation of the bearings considerably, which in turn reduces effort and the associated costs.

Tried-and-tested and highly cost effective, 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, including attached bearing rings can be integrated.
