New from Jarshire is a lightweight, lug-type carbon fibre airshaft for unwind and rewind applications when using cores. Designed by Svecom PE, it is said to have two exclusive features.
The lug seats are made of ‘new technology’ high strength steel designed to avoid any possibility of surface cracking and to distribute the load uniformly over the whole carbon section. This increases the shaft life greatly when compared to competitors’ carbon shafts that may be covered by a heavy steel sleeve, it is claimed.
In addition, the body ends have a new technology steel insert with a special steel-carbon interface to transmit the torque safely.
Expansion is achieved by a single inflatable tube that, when air is applied, exerts pressure to engage the lugs thus locking the cores. The expanding lugs can be either steel, plastics or rubber covered, depending upon core material and torque requirements, and the journal ends are always custom fabricated from a variety of steel materials.
Standard diameter of the shaft is 3 inch and standard lengths are available between 800-2,500mm. Other sizes can be supplied to suit specific requirements.
