Slewing Rings find a multitude of applications on ships. Below is an examples of an offshore supply vessel.

Gear ring (external diameter of about 1,700 mm – 67 in) with hardened toothing for a crane winch.

Special Slewing Rings (wire race bearing) with stainless steel rings for a slip ring assembly on an FPSO. A highly accurate and very narrow bearing gap ensures the necessary EExd - explosion pressure protection. In case of an explosion on the upper side of the wire race bearing there must be no possibility of ignition sparks penetrating through the bearing and causing a secondary detonation on the lower side.

Ball Slewing Ring with root and flank hardened external toothing for a ship`s thruster on a vessel. The stamp by Lloyd‘s Register of Shipping can be clearly seen.

Slewing Ring for the launching gear of a sea rescue boat.

Three Row Roller Slewing Ring with internal toothing and an external diameter of about 3,000 mm (118 in), for a large shipboard crane. 36
