Clements Marine offer a complete range of steel half couplings and adapters. These can be manufactured with tapered or parallel bores, and with male or female gearbox output flange fitting to suit the individual installation. Split couplings are also available with scalloped flanges that enable the removal of clutch parts with the coupling in situ.

The Evolution Flexible Shaft Coupling (EFSC) solves misalignment, absorbs and dampens shock loads and shaft vibrations, prolongs the life of machinery, and isolates metal-to-metal for quietness.
The EFSC is comprised of four major components: 1) a spool flange machined to bolt directly to the reduction flange; 2) a large circular rubber flex joint that's replaceable; 3) a split flange coupling for the shaft with pinch bolts, set bolts, and keyway; 4) a retainer cover that serves to protect the rubber flex joint, capture all bolts, and improve overall strength of the unit.
The Evolution Flexible Shaft Coupling uses quality construction and few parts and is easily installed.

The VULASTIK-L coupling is a torsionally flexible rubber coupling, that compensates axial, angular and, to a certain degree, radial displacement of the connected machines. Four rubber qualities and silicone are available in order to tune the coupling to the various system requirements. VULASTIK-L couplings are available with one elastic element in standard design or with two elements acting in parallel in Dual design. The main parts of the VULASTIK-L coupling are hub and flanged casing, between these, the disc-shaped element is arranged. This disc element is connected by vulcanization at its inner radius, the outer radius is connected to the flanged casing by a "plug-in" toothing. This toothing provides the axial "plug-in" feature and compensation of shaft displacements. The permissible angular coupling displacement is 0.5°. The VULASTIK-L elements are made from heat-resistant rubber, the admissible ambient temperatures range from -45°C to +90°C. Alternative elements in silicone are available (ambient temperatures range from -45°C to +120°C). With respect to a long lifetime, however, consideration should be given to sufficiently large ventilation cross sections. This is very important when considering bellhousing.

The highly flexible RATO-DS coupling has been specially designed for use in installations requiring a high level of torsional flexibility and medium level of misalignment capacity. Supplementing the "all-round" RATO-S the RATO-DS has been developed to offer an application - orientated coupling design. Specially for rigidly mounted ship´s main propulsion. The 3 available stiffnesses enable a good tuning of the system with respect to both the transient and steady-state torsional vibration response. In the tradition of VULKAN couplings, a backlash free torque transmission is achieved. When required a torque limiting device can be fitted. The normal misalignments caused by foundation deflections, heat etc. can be adequately compensated for by the radial, axial and angular flexibility of the RATO-DS. Dynamic safety was the prime consideration in the design of the RATO-DS coupling. This is reflected in the element in the element shape - mechanical and thermal capacity and by using a friction loaded bolting arrangement. The large ventilation holes located in the couplings metal parts ensure that any heat generated in the coupling is effectively removed. The advantages of the compact dimensions together with the possibility of radial removal of the element leads to a weight efficient coupling assembly in the drive system.

The highly-flexible RATO-S coupling is a torsionally flexible rubber coupling that compensates radial, axial and angular shaft displacements of the connected machinery. The torque is transmitted by elements loaded in shear. The different torsional stiffnesses and damping factors available provide the possibility to satisfactorily tune the torsional vibration behaviour of the drive system. The essential parts of the coupling are: the torsionally flexible part, the membrane part and the connecting parts. The torsionally flexible part consists of elements, which can be arranged in one row or more rows respectively, dependent on the coupling size and the stiffness level. The flexible elements are divided into several segments. Due to the element segments and in the case of multi-row couplings, a displaced arrangement of the segments gives a good ventilation and cooling of the elements. With certain sizes the segments have additional ventilation holes. The segmental construction also assures easy handling at installation.

Complementary to the "all-round" RATO-S coupling the highly flexible RATO-R coupling has been specially designed for use in installations requiring a high level of torsional flexibility and misalignment capacity. Inherent features of the design include the high dynamic load capacity and good rotational dynamic properties due to the low rotating inertias. The area of application is primarily in high-speed main/PTO systems driven by a Diesel engine or electric motor. In the low to middle torque range where the handling and installation of a complete element is practibable the RATO-R coupling is an additional alternative. A good tuning of the systems´s torsional vibration characteristics is possible due to the variety of torsional stiffnesses and element configurations available. The radial, axial and angular flexibility of the RATO-R coupling, with the shortest possible installation length, enables good compensation of shaft misalignments due to the flexible mounting of the prime mover, foundation movements etc. to be achieved. The use of relatively soft annular membranes permits, in the event of an axial vibration excitation, an efficient isolation of the system-effectively protecting shaft bearings. By avoiding noise paths, direct metal to metal contact, the RATO-R has excellent noise-attenuation properties.

The PROPFLEX N coupling has been designed and developed to be installed on board of pleasure crafts, where comfort of the passengers requires a high vibrations isolation degree. It has to be positioned between the gearbox and propeller shaft in order to reduce the vibrations and noise transmission coming from the shaft line itself. It can compensate axial, radial and lateral misalignments and thanks to its modular design can be supplied in different lengths and complete of spools and hubs to match with the most known gearboxes and propulsion systems. It is particulary suitable for all application where the propeller thrust is already absorbed by the propulsion system. As there is no direct contact between metal parts, the PROPFLEX N coupling is a noise isolating coupling. Thanks to its own design, the PROPFLEX N coupling can be dismounted radially, without moving the connected machineries. Also available in steel and aluminium execution.

It can compensate axial, radial and lateral misalignments and thanks to its modular design can be supplied in different lengths and complete of spools and hubs to match with the most known gearboxes and propulsion systems. It is particulary suitable for all applications where a thrustblock is not foreseen on the shaft line. The PROPFLEX S coupling can transmit directly the propeller thrust to the thrustblock into the gearbox. As there is no direct contact between metal parts, the PROPFLEX S coupling is a noise isolating coupling. Thanks to its own design, the Propflex S coupling can be dismounted radially, without moving the connected machineries. Also available in steel and aluminium execution.

eliminates leaks where fittings are close to tight
bends.
• High integrity single piece moulding improves the
reliability and strength of fittings.
• Outer sleeve incorporates collet cover, thus
preventing accidental tube release.
• No collet clips are used thus the Whale system
reduces costs, speeds up installation time and
ensures complete installation every time.
