Sterntubes and Sterntube Materials TUBE MATERIALS Clements Marine otter a range of materials for sterntube manufacture. These are as follows:- 1. Polyester resin GRP tube. 2. Non-ferrous metal tube. 3. Cast non-ferrous LG2 gunmetal tube 4. Carbon steel tube. Our Polyester resin GRP tubes can be machined to suit the type ot shaft seal or packed gland to be installed. Refer to TD02, Self Aligning Shaft Seals All GRP tubes are manufactured with sufficient accuracy tor cu ties s bearings to be fitted without further machining of the tube. Tubes can be supplied in a wide range of sizes and lengths to suit individual customer requirements. STERNTUBE ARRANGEMENTS Clements Marine can supply a wide range of sterntube arrangements according to customer preference, hull design, and engine performance and type. A range of recommended solutions are outlined below and on page 2 ot this data sheet. Generally, optimising cost and maintainability with durability and longevity of product life, the sterntube can be constructed using GRP, bronze or fabricated steel. Similarly, the shaft sealing arrangement is normally a dripless watercooled StrongSeal assembly, or a conventional bronze housing and packed gland. -Clements Marine recommended half cutless bearing and dripless, water-cooled Strong Seal assembly suitable for high performance leisure and medium duty The StrongSeal dripless. self aligning seal assembly with its integral cast bronze hull fitting and cutless bearing housing, (see TD02, tor shaft seal details)
