This is an aqualube bearing which offers an excellent solution for water lubricated shaft applications.
Aqualube bearings are manufactured with longitudinal grooves that form a hydrodynamic wedge, or water film between the shaft and the bearing, even during slow speeds. This water film allows shock absorption reducing vibration and noise to minimize wear. Aqualube bearings are manufactured from chemical and oil resistant nitrile rubber which are available with brass and non-metallic (Phenolic) shells to fit many different applications. Every bearing is inspected to ensure quality.
