Non Metallic Marine Cutless Bearing Water Lubricated Composite Sleeve Bearing
Non Metallic Marine Cutless Bearing Water Lubricated Composite Sleeve Bearing
WTG non-metallic marine cutless bearings are water-lubricated composite sleeve bearings for shaft systems requiring corrosion resistance, lighter weight and non-metallic shell options.
The fiber reinforced composite shell and NBR rubber lining support seawater lubrication, cooling, stable shaft support and reduced maintenance for marine propulsion systems.
The SKU table is organized by metric and inch shaft diameter to help buyers match common shaft sizes quickly. Custom outside diameter, length and groove design can be manufactured from drawings.
Suitable for ferries, tugboats, fishing vessels, offshore vessels, yachts, shipyards, repair yards and propulsion OEM projects.
For quotation, please provide shaft diameter, housing bore or outside diameter, bearing length, quantity, drawing if available, vessel type and operating water environment.
