115mm Brass Shaft Bearing - Marine Grade

115mm Brass Shaft Bearing (5.5 Inch External)

Elevate your boat's performance with our exceptional water-lubricated shaft bearings. With a precise metric inner diameter and a precisely crafted imperial outer diameter, these bearings deliver outstanding reliability on the water.

Constructed from durable brass and featuring a unique internal rubber design with advanced axial channels, our bearings ensure optimal lubrication and performance. The rubber’s natural elasticity significantly dampens shocks and minimizes vibrations, providing you with a smoother and more enjoyable sailing experience.

Innovative Aqualube Technology

The Aqualube bearing technology transforms marine performance by creating a hydrodynamic water cushion between the shaft and the bearing, functioning even at lower shaft speeds.

Water, being an abundant and effective lubricant in marine environments, enhances cooling and reduces friction. Longitudinal grooves promote water flow, generating a thin lubrication film that encircles the propeller shaft and the bearing, keeping them separated and well-protected.

Robust and Easy to Install

Our high-grade brass bearing is meticulously machined for precise edges, simplifying the installation process. The nitrile rubber is engineered to resist oil and chemicals, securely bonded to the brass shell. Slimmer casing options are available for smaller craft that need brackets.

Installation of sleeve bearings is straightforward, utilizing light press-fit techniques and can be secured with tapered screws.
