Cutlass Bearings

Cutlass bearings and typeCutlass bearings are rubber-lined bearings that work under the elastohydrodynamic concept with water lubrication. The fluid architecture of the bearing uses the principles of lubrication to permit the creation of hydrodynamic water wedges on the surfaces of the bearing by water from the grooves.

The term “Cutlass” is based upon the ability of such bearings to move over their surface and into the flushing slabs of abrasive matter such as sand and marine species. These abrasive particles do not reach the surface of the bearing and cause little shaft trims.

Cutlass bearings have a large number, including propeller shaft rollers in bolts, rudder bearings, and cutter bearings in a range of crafts. Cutlass bearings in hydroelectric power generators, central fugitive pumps, and other water-submersible equipment are used in addition to navy applications.

The cutlass bearing provides structural support with integrated resilience when used in a propeller shaft housing, which enables the bearing to bend in compliance with the layout of the boat and thus avoids the shaft bearing or shaft wear. The bearing also decreases the vibration and noise in the ships. It also absorbs shock and is virtually maintenance-free.
