Michigan Wheel Aqualube Brass Cutlass Bearing – Imperial Sizes, 3/4"–4" Shaft, Water Lubricated

The Michigan Wheel Aqualube cutlass bearing is designed for marine propulsion systems, providing reliable shaft support while reducing friction, vibration, and wear.

The bearing features a marine bronze shell combined with a nitrile rubber lining, ensuring durability and resistance to abrasion in demanding marine environments.

Water lubrication is achieved through longitudinal grooves in the rubber lining, allowing a hydrodynamic water film to form 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 to create a hydrodynamic wedge between the shaft and the bearing, reducing wear and improving efficiency in marine applications.
