marine propeller

The shaft coupling is the component which joins the propeller shaft to the gearbox output flange. Some are bolted directly to the gearbox but many installers use a flexible couple, such as R&D flexible couplings, which would then bolt to the gearbox. Our range includes couplings for most popular transmission types, bored for imperial or metric shafts. Besides the standard coupling, the Solid Half Coupling, Clamp on or Split Half Coupling, Bobbin Coupling and Coupling Adapters are also available. Material: carbon steel, stainless steel Processing methods: forged and lathe machining Dimensions: designed according to the shaft and gearbox.

It is controllable pitch propeller,, The material is Ni-Al-Bronze which has very good physical properties and corrosion resistance, mostly apply for marine ship propeller. This propeller is 5 blades controllable pitch propeller, with the diameter 4.2meter, and 5.6 tons, polished with popular pattern, high efficiency and saving fuel by adjusting the propeller pitch when sailing. The propeller hub and blades is mainly produced by 5 axis CNC machine, all dimensions must be accurate.
