Aqualube Brass Bearing For Marine Shafts With Hydrodynamic Water Film Water Lubricated 3 1 8 Inch ID 4 1 2 Inch OD 12 1 2 Inch Length Durable Marine Bearing For Boat Wheel Systems

Single Bearing: Hydrodynamic Water-Lubricated Marine Bearing
✔️ 3 1/8 in ID, 4 1/2 in OD, 12 1/2 in length, stainless marine-grade

This water-lubricated bearing is designed for marine shafts and wheel systems, offering a hydrodynamic water film for smooth operation in wet environments. Built from corrosion-resistant stainless steel, it thrives in boats and waterside gear.

✅ Hydrodynamic water film between shaft and bearing for reduced shock, vibration, and wear
✅ Stainless steel construction resists corrosion in marine settings
✅ ID 3 1/8 in, OD 4 1/2 in, length 12 1/2 in
✅ Suitable for boat wheel systems and other onboard shaft applications

💡 What is a water-lubricated bearing and why is it used on marine gear?

Water-lubricated bearings rely on a thin film of water to minimize friction and wear in wet environments.

- Uses hydrodynamic grooves to maintain the water film and support load - Reduces noise and wear in marine shafts - Common in propeller shafts, wheel systems, and other boat gear ✝️
