Michigan Wheel Aqualube Brass Cutlass Bearing – Metric Sizes, 22–110 mm Shaft, Water Lubricated

The Michigan Wheel Aqualube cutlass bearing is a high-performance water-lubricated bearing designed for marine propulsion systems. It supports propeller shafts while minimizing friction, vibration, and wear.

The bearing features a marine bronze shell combined with a specially formulated nitrile rubber lining, providing excellent resistance to abrasion and long service life in demanding marine environments.

Water lubrication is achieved through longitudinal grooves in the rubber lining, allowing the formation of a hydrodynamic water film between the shaft and the bearing surface. This prevents direct contact and ensures smooth operation even at low shaft speeds. :contentReference[oaicite:0]{index=0}

Aqualube bearings use water as a lubricant, forming a hydrodynamic wedge that separates the shaft from the bearing surface, reducing wear and improving operational efficiency in marine applications.
