Metric sized Cutless Bearings
Johnson Duramax Marine Cutless sleeve bearings for heavy-duty commercial, government and pleasure craft applications, feature a specially formulated nitrile moulded rubber lining firmly bonded to a shell material. Shells for sleeve bearings are seamless naval brass and are also available with a rugged non-metallic shell.
The rubber, a proprietary formulation of extremely tough chemical and oil-resistant nitrile, is moulded to fit the shaft in accordance with U.S. Navy BuShips approved clearance for efficient water lubrication. Radially-spaced grooves have edges rounded to promote the flow of water between the journal and the bearing rubber in a continuous lubrication film. Grit particles and other abrasives wipe into the grooves and are flushed away.
