Michigan Wheel Aqualube Brass Cutlass Bearing – Mixed Metric/Imperial Sizes, 20–80 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 reducing 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 marine environments.

Water enters the bearing through longitudinal grooves, forming a hydrodynamic 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}
