Marine Cutless Bearings

PTFE based Cutless Bearings

Cutless bearings refer to rubber-lined bearings operating with water lubrication on an elastohydrodynamic principle. … The name Cutless is derived from the ability of such bearings to pass abrasive materials such as sand and marine organisms across its surface and into the flushing grooves.

Cutless bearings are tube shaped and typically made from bronze, marine grade brass or stainless steel and are lined with nitrile rubber. The rubber is grooved where it meets the propeller shaft to enable water to pass through the grooves in order to lubricate the bearing.
