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

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

The bearing features a non-metallic phenolic shell combined with a specially formulated nitrile rubber lining. This construction ensures high resistance to abrasion, corrosion, and long-term durability in marine environments.

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

Aqualube bearings are designed to allow abrasive particles to pass through the grooves and be flushed out by water flow, reducing wear and protecting the propeller shaft in demanding marine environments.
