Propeller Shafts and Sealed Devices

Takazawa Boasts Japan's Highest Quality Propeller Shafts and TW Sealed Sterns

Takazawa's propeller shafts, which are made from materials that we jointly developed with a leading maker of special steels, have obtained the absolute confidence of users in respect of their corrosion resistance, hardness and durability.

We have a rich lineup of materials in stock, including stainless steels such as SUS304 SUS316, TXA208 and SP1, brasses such as TS-1AS, and other materials such as KSFR45, KSFR60, etc.

In addition, our sealed device, the TW Sealed Stern has already been mounted on some 50,000 vessels in Japan as a stern pipe watertight device (patented) designed to protect the lives of people at sea.

This device features a preeminent watertight capability thanks to a diaphragm system, reduced frictional resistance due to a promotion shaft, and energy saving made possible by improvements in rotational conductivity. Moreover, the design eliminates the problems associated with abrasion and corrosion of the packing gland section, while adjustment of the packing gland when sailing after berthing is not required. Employing ceramic and carbon for the sealed surface, the TW Sealed Stern is a sealing device that has been highly praised by users who value the sense of safety engendered by its unrivalled abrasion durability.
