Centa says large driveline angles with permanent displacement up to 8infinity are permissible with a further 3infinity available to accommodate movement due to soft engine mounts. This factor, together with the compact design and short overall lengths gives substantial freedom of installation and minimises layout problems, says the company.

They say additional torsional stress, common to all reciprocating piston engines, is handled by the Centalfex A Series coupling with its torsional deflection capacity up to 8infinity.

Centa says structural vibration is absorbed and shafttransmitted noise from the engine/gearbox is eliminated since there is no metal-to-metal contact between it and the hull.

The thrust bearing is rubber mounted and has a spherical outer ring, which Centa says ensures that it is self-aligning relative to the driveshaft.

A propeller shaft clamping device with intermediate bushes will fit an extensive range of propeller shaft diameters and adapters are available to connect the couplings to all types of marine gearbox.
