JQCS 49 Stern Shaft Bearing is suitable for inland water vessels whose stern tube working medium is oil. The stern shaft bearing is a rotating body that supports the ship shaft system, by reducing the friction coefficient in the process of movement and ensuring its rotating accuracy. The stern shaft bearings mainly bear the weight of stern shaft and propeller. The shaft system is an important part of ship propulsion system, and stern shaft bearing is the core component of shafting.

It consists of oil lubrication and water lubrication. The materials of stern shaft bearing includes rubber bearing and polymer bearing.
