propeller shaft

The stern shaft materials have passed EN10204-3.1 certification, covering various grades of: low carbon steel, alloy steel, stainless steel, ductile iron, aluminum alloy, copper alloy, titanium alloy. The main processes are: free forging, die forging, rolling ring, high pressure casting, centrifugal casting, normalizing, quenching and tempering, solution treatment, aging treatment, carbonitriding, turning, milling, drilling, grinding, hobbing, high frequency quenching, galvanizing, chrome plating, anodizing, powder spraying and other processes. The propeller shafts length: Max 16000mm,max dimeter is 500mm, single piece weight: Max 16 Tons, at the same time we are good at terminal machining of complex products, dimension accuracy: Min 0.01mm, roughness: Min Ra0.6.

A stuffing box is an assembly which is used to house a gland seal. It is used to prevent leakage of fluid, such as water or steam, between sliding or turning parts of machine elements.

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.
