product details:

Function:

Cutlass rubber bearings function similarly to other bearings by minimizing friction between a rotating shaft and a stationary housing. However, unlike standard bearings that rely on grease or oil for lubrication, cutlass bearings utilize water:

• Cylindrical Shell: The bearing is made of a cylindrical shell, typically composed of brass, stainless steel, or a composite material.
• Rubber Lining: The inner surface of the shell is lined with a specially formulated nitrile rubber compound.
• Water Lubrication: As the shaft rotates within the bearing, water enters through grooves in the rubber lining. This water creates a lubricating film between the shaft and the rubber, reducing friction.

Key Features:

• Self-Lubricating: No external lubrication is required, making them ideal for submerged environments where traditional lubrication methods are impractical.
• Low Friction: The water film provides excellent lubrication, minimizing energy losses and wear on the shaft.
• Corrosion Resistant: The materials used in cutlass bearings, like brass and nitrile rubber, offer good resistance to corrosion in saltwater environments.
• Reduced Noise and Vibration: The water lubrication dampens noise and vibration, leading to smoother operation.
• Simple Maintenance: Regular inspection is recommended, but cutlass bearings generally require minimal maintenance compared to grease-lubricated bearings.

Advantages:

• Reduced Maintenance Costs: Eliminates the need for regular greasing, saving time and resources.
• Environmentally Friendly: No risk of oil or grease contamination in the water.
• Accommodates Shaft Misalignment: The rubber lining can tolerate slight misalignments between the shaft and the bearing housing.
