Conventional swivels can be extremely susceptible to corrosion due to the steel ball bearing used in standard designs. In order to avoid direct contact with the seawater, bearings have traditionally been sealed and filled with oil, however even the smallest penetration of water can cause destructive corrosion.

To address this, K.U.M. designed a high-tensile titanium Swivel that uses a ceramic ball bearing instead of a steel one. This puts the risk of corrosion within the Swivel at zero. The result is a Swivel that is maintenance-free and offers maximum protection even if seawater penetration does occur.
