Oil lubricated stern tube are specially design for steel vessel which are welded directly to hull. The design is well taken in consideration to minimize deformation due to welding of heat.

Steel Struts also called as Shaft brackets or ‘A’ brackets are manufactured as single cast in special material such as steel, stainless steel, mild steel, Aluminum or Aluminum bronze. The shape of the bracket is custom designed to meet the hull shape & to guarantee the lowest drag.

These types of stern tube are mainly used for fishing boats & yachts. Depending on the application, a water inlet, usually connected to the engine cooling system can be set up on the tube close to the seal. This mounting is used when the engine / gearbox are mounted on soft pads, and there is no need for intermediate bearing between the rear bearing and coupling.

1. SERIES 'A'

This stern tube assembly is used where the propeller shaft overall length is such that it requires intermediate bearing and distance between the dead and FWD face of the rudder is less, due to this outer bearing gland is not possible to use. It includes outer bearing a bronze tube & water lubricated gland assembly with half bearing.

2. SERIES 'B'

This stern tube assembly is used where the engine is flexibly mounted, so there is no use of intermediate bearing and the distance between the deadwood and forward face of the rudder prohibits the use of outer bearing. It includes a outer bearing, a bronze tube and a flexible inboard gland assembly. The bearing is lubricated by water, usually supplied from the engine cooling system.

3. SERIES 'C'

This stern tube assembly is used where the engine is solidly mounted to take out any deflection caused by engine movement. It includes of a outer bearing, a bronze tube and a grease lubricated gland assembly. The outer bearing is normally fitted to the vessel's dead wood. The grease lubricated gland assembly is fitted to an inboard bulkhead and is lubricated by grease

These rudders are mounted through the hull in a rubber tube fixed inside to the hull. They are generally cast in one piece either in Nickel Aluminium Bronze or Manganese Bronze. The tubes are cast in gunmetal LG2 and can be grease lubricated through an injection point provided.

The shaft couplings are manufactured in forged steel. The couplings are supplied and are machined to match the gearbox output flange. The couplings can be supplied according to rules of any classification society.

The water lubricated gland is used where an intermediate bearing is required on the inboard end of the stern tube. It is used as intermediate bearing between the 'P' bracket and the gearbox as well as forming a watertight seal at the point where propeller shaft enters the hull.

SGP Transom rudders assemblies are precision machined from one piece castings in either Nickel Aluminium Bronze or Manganese Bronze. The rudder housings are fitted with seals to prevent the ingress of water .

The GRP rudder trunk assembly is designed for hull installation. The tube should be glassed to the hull at the bottom and supported at the top by a transverse floor. The tube is manufactured from high quality marine grade GRP tube.

These types of stern tubes are usually used in High speed yachts, High speed ferry boats & passenger vessel where an intermediate bearing is may required or not required. It includes a GRP tube, flexible gland and water lubricated bearing bush. Further we provide New Zealand make Kiwi Shaft Seal along with GRP Tube which is the ultimate solution for vessel & crew safety.
