DYNAMIC ENGINEERS AND EXPORTERS

Our servo couplings are torsionally stiff shaft couplings soft in bending serving as a connection element between the drive unit and the measuring sensor. They transmit torque, free from backlash and conformally, making our backlash-free shaft couplings highly accurate. They also allow for compensation of radial, axial and angular displacements. Thanks to the high variety of coupling types and hub designs we are able to supply the right coupling for almost every application.

The RIGIFLEX®-N steel laminae couplings are used wherever reliable and backlash-free torque transmission with simultaneous shaft displacement is required.

The steel laminas are designed as layered, waisted laminae sets. They are connected fully backlash-free with hubs and flanges via positive-locking dowel screws.

The single-cardanic servo laminae coupling (single-jointed coupling) RADEX®-NC High Torque EK was developed for applications in servo technology. The single-cardanic design is characterized by conformal torque transmission and high torsion spring stiffness.

Servo laminae coupling with clamping hubs:

RADEX-NC EK with clamping hubs is a single-cardanic standard series. The clamping hubs make the servo laminae coupling easy to assemble. The hubs are fastened to the shaft by tightening one single clamping screw eccentrically positioned. Here both frictionally engaged connections without feather keyway and positive-locking connections with feather keyway are available.

Servo laminae coupling with clamping ring hub:

RADEX-NC EK with clamping ring hub is a single-cardanic series for high speeds.

The two-part, rotationally symmetric taper hubs ensure smooth running along with a safe, frictionally engaged shaft-hub connection even with high speeds. 

ROTEX® torsionally flexible jaw couplings are elastomer couplings characterized by a compact design.

Despite low weights and mass moments of inertia of the elastomer couplings they are able to transmit high torques. The compact shaft couplings are characterized by a long service life and sound operating characteristics generated by allover machining.

Thanks to the elastomer (elastomer spider) between the coupling hubs of the jaw couplings shocks respectively torsional vibrations in the drive train are damped. The high temperature-resistant spider material T-PUR® (elastomer) is available in various degrees of hardness. The torsionally flexible ROTEX couplings are used in almost every range of general machinery and plant engineering.

The placement of the hubs of the GEARex all-steel gear coupling can make for a very short shaft distance, regular shaft distance, and short shaft distance along with a different mounting position of hubs as per customer requirement. The hubs of the gear coupling can be locked and are connected to the coupling sleeve with threaded joints or interference fit. The construction of the sleeve and hub enables the transmission of high amounts of torque.

Magnetic couplings with containment shrouds are particularly suitable for reliable sealing of liquids and gases.

The magnetic coupling MINEX®-S with containment shroud between the magnetic rotors ensures hermetic separation of the driving and driven side, e. g. in pumps and agitators. With critical media like aggressive acids and bases, it serves for reliable static sealing, thus preventing serious leakages.

REVOLEX are torsionally flexible, fail-safe pin & bush couplings that are mainly used in applications with high torques and drives subjected to shocks. They are specifically solid, fail-safe, and compensate for any kind of shaft displacement while transmitting the torque reliably. The REVOLEX pin & bush couplings can be plugged in axially and are characterized by short dimensions. These pin & bush couplings are generally equipped with hydraulically dismountable pins which means that special tools are not required for disassembly. The coupling components of the REVOLEX® pin & bush couplings are maintenance-free and allow for a smooth disassembly of elastomer rings along with pins in mounted condition.

REVOLEX® pin & bush couplings are usually provided with 80 ShA NBR elastomer rings with the standard material being a true all-rounder. NR elastomers are available for low-temperature applications. Apart from that backlash-free, electrically insulating NBR elastomers (coloured in blue) are available which are mainly used in cableway drives.

The two-parted BoWex curved-tooth plug-in coupling is made of nylon and is a low-cost version for small performance ranges.

The single-cardanic gear coupling has a low net weight and is available from stock with a finish bore for standard shafts and feather keyway acc. to DIN 6885 sheet 1 and thread for setscrews.

The BoWex junior gear coupling is suitable for compensating for axial and angular shaft displacements.

The heart of the RADEX-N steel laminae coupling are the laminae sets along with their connection to hubs and spacers.

The high-strength and special dowel screws are reciprocally screwed to hubs and spacer allowing for a combination of friction and positive-locking fit.

In this way, KTR laminae coupling ensures high power density with simultaneous ease of displacement and low restoring forces.

KTR has developed a new standard material for its spiders. The imporoved PU material T-PUR is resistant to significantly higher temperatures and has a considerably longer service life than the previous PU material material. From visual point of view, KTR has characterised the material T-PUR by the colours Orange (92 Shore-A), Purple (98 Shore-A) and Pale Green (64 Shore-A)

The double-cardanic curved-tooth gear coupling BoWex M is suitable for all applications of general engineering and hydraulics. The material combination of nylon/steel of our gear couplings enables maintenance-free operation, grease or oil lubrication can be done without. The steel hubs allow for an extensive stock range with finish bores acc. to ISO and feather keyway acc. to DIN 6885 sheet 1 as well as taper and inch bores for hydraulic pumps and customized adjustment. 

The torsionally flexible, fail-safe shaft coupling POLY-NORM AR is a compact two-part shaft coupling for torsional vibration-damping power transmission.

The hubs made of cast iron identical in design make the standard version POLY-NORM AR specifically low-priced.

For mounting the shaft coupling the hubs are simply pushed onto the shafts and fastened axially through setscrews.

Applications of our torsionally flexible, fail-safe shaft coupling:

The POLY-NORM AR shaft coupling is used in almost all fields of general engineering, here mainly in the pump industry.

TOOLFLEX is a torsionally stiff and flexible metal bellow-type coupling (all-metal coupling) with a bellow made of stainless steel and coupling hubs made of aluminum. The coupling hubs of our metal bellow-type coupling in size 55 and 65 and as a type KN are made of steel.

The metal bellow ensures optimum compensation of axial, radial and angular displacements with conformal torque transmission. At the same time the geometrical shape of the metal bellow-type coupling provides high torsion stiffness and a low mass moment of inertia. Apart from that it is resistant to media effects and critical operating conditions.

Applications of our metal bellow-type coupling TOOLFLEX:

Metal bellow-type coupling for drive technology, automation technology, medical technology, servo drives, packaging technology, machine tools, etc. For the different applications and mounting conditions of the TOOLFLEX metal bellow-type couplings two different bellow lengths are available.

RRL coupling is a Jaw Spacer coupling which is known as Radially Removable/Removable L type coupling. Spacer lengths available are 90,100,140 and 180mm.

Cone-Flex couplings consists of sets of resilient “ Cone-Flex” rings with pins & nuts and two flanged hubs of graded cast iron. These “ Cone-Flex” rings are specially shaped to permit the rubber to deflect in all directions and give over four times torsional flexibility as compared to a plain bush.

ROTEX GS is a three-part servo coupling (elastomer coupling) backlash-free under prestress. The different hub types and various kinds of Shore hardness provide the optimum coupling for every application in automation technology.

It is used wherever drives have to be positioned accurately. Despite their vibration-damping properties, the coupling is torsionally stiff so that you do not have to cut back on precision even with highly dynamic servo drives. The ROTEX GS backlash-free elastomer couplings allow for simultaneous compensation of radial, axial, and angular displacements.

The backlash-free servo coupling ROTEX GS uses the construction kit system, it is available in a high variance of different hub types which can be combined within one coupling size.

The choice of the hub material depends on the size and the hub is either made of aluminium or steel. Both frictionally engaged connections without feather keyways and positive-locking connections with feather keyways are available.

Disc couplings are non-lubricated, all-metal components known for their remarkable torsional stiffness. They rely on torque transmission through discs, which alternate between the drive and driven flanges on the same bolt circle within the disc pack assembly. The coupling's misalignment capacity hinges on factors like pack thickness, disc material, the number of drive bolts, and the span between them. The total torque capacity, on the other hand, is determined by the disc pack thickness, total drive bolts, and their arrangement.

Escodisc couplings usually feature two flexible elements and a spacer, ensuring excellent inherent balancing properties and often negating the need for additional balancing at motor speeds. These couplings comply with API 610 standards. The ESCODISC DPU series leverages ESCO Couplings' original disc pack design, enhancing reliability, performance, and equipment longevity.

The ESCO gear coupling is a robust, grease-filled coupling, offering exceptional torsional rigidity. It consists of two hubs with external multi-crown teeth and two flanged sleeves with straight internal teeth. These sleeves are securely bolted together using high-strength, corrosion-protected fitted bolts and nuts. An endcap on the opposite side of the flange, either internal for small or screwed for larger couplings, houses an o-ring for sealing purposes. The ESCO gear coupling is designed to transmit torque through friction, preventing fretting corrosion. Its teeth maintain continuous contact, allowing for angular, parallel, and axial misalignment within specified limits. The standard ESCO gear can accommodate up to 1.5° angular and parallel misalignment. The FST series is a reliable choice for a wide range of industries.
