RANGE OF MARINE COUPLINGS
HALF COUPLINGS:
Type FL Ø 25 – 60 mm
Flange couplings manufactured in C45 steel, completely machined. The flange couplings are galvanically coated. The flange couplings have a taper of 1:10. The R indicated in the table represents the number of bolt holes in the flange. All dimensions in mm.
Fully Machined Steel Flange Couplings With Keyway Ø 70 – 300 mm
Steel flange couplings can be manufactured on request whole or partly. When ordering, please specify the dimensions of the gearbox flange. Standard the flange couplings have a tapered bore 1:10 and a keyway. All dimensions in mm.

CENTA COUPLINGS:
Centa offers the perfect, innovative marine transmission. It is a combination of well-proven designs with unique features – freedom in alignment and installation, together with damping of noise and vibration within the transmission. Centa Flex couplings have one or more Centa Flex rubber elements. The rubber elements interrupt structure born noises and dampen noise and vibrations for the highest level of comfort in the boat.
Common Features Of Centa Flex Couplings:
– A broad range of rating and sizes.
– Short, lightweight design.
– Integrated propeller shaft clamping device which can easily be adapted by intermediate bushes for an extensive range of propeller shaft diameters.
– Patented design.
– The thrust bearings have a spherical outer ring, which means they will always align themselves perfectly to the propeller shaft for
optimum bearing lifetime.
AQUADRIVE MODULINE COUPLINGS
Aquadrive couplings consist of a CV joint, a thrust bearing and an adapter. The CV joint consist of two universal joints connected by a floating axle, which allows axial and radial movements. The thrust bearing transfers the thrust of the propeller through a rubber suspension on the foundation of the craft instead of the gearbox. The Aquadrive Moduline is modular, allowing the overall length to be reduced to 70% and the weight to 75%. The Moduline consists of a thrust bearing being connected to the shaft by a sleeve set. The joint is attached to the thrust bearing with an adapter at one side and connected to the gearbox on the other side with an adapter flange. There is a gearbox adapter available for all existing gearboxes. Aquadrive Moduline couplings are
available for power between 5 and 235 hp.
PYTHON DRIVE COUPLINGS
The Python-drive is a complete drive system for yachts, barges, etc.. With a Python-drive installed you will eliminate the need for alingnment of propeller shaft and gearbox/engine. Axial movement caused by the propellers’ thrust are eliminated and the thrust is passed onto the hull by means of the special suspension of the trust unit. The maintenance-free cv shaft forms the heart of every Python-drive. The heavily built thrust bearing unit is also maintenance-free. The thrust bearing unit is mounted by means of a clamping sleeve. This sleeve centres the propeller shaft where it should be centred; right after the cv shaft of the Python-drive. The cv shaft ensures a constant rpm of the propeller shaft, even at uneven angles, which decreases the wear of rotating parts in the propulsion system. Another big advantage is the very limited built-in length the Python-drive needs. The unit is supplied complete with all needed mounting gear, such as an adaptor flange for most common gearbox types, acv shaft, a robust thrust bearing unit and all bolts, (locking) nuts, and rubbers to take the thrust. For 19 mm up to 100 mm (and imperial sizes), complete units are available. Conical shaft sleeves are also an option. CV shafts for torques up to 1.500 Kgm (14.7 kNm) as well as longer or custom
made shafts are also available on request. Thrust bearing units can be supplied as separate units to be mounted on any position on the propeller shaft.
