CENTAX torsional couplings are built for diesel and gas-driven compressors, pump drives, and similar industry applications. Economical, easy to mount, and simple to install, the CENTAX couplings are a no-fuss solution built with unparalleled quality. The torsionally soft CENTAX couplings feature a rubber-in-shear element with high torsional and radial flexibility. The coupling designs can be plugged in axially for maximum ease of mounting. The cost-effective, compact design makes the CENTAX portfolio a superior solution for many applications. With many options and variations to increase damping qualities, compensate for axial, angular, and radial misalignments, and cover a range of torques from 400 to 800,000 Nm, there are a vast array of solutions within the CENTAX portfolio.

The CENTAMAX series is characterized by a highly efficient self-ventilating design. The high thermal capacity (HTC) design features a superior allowable power loss compared to other conventional couplings. This ensures longer equipment life in newer, more torsionally active low-emission diesel engine systems. The HTC design also makes CENTAMAX a cost-effective solution, as less costly coupling designs may be used in many applications. The torsional flexibility and elasticity of this rubber-in-shear design shifts critical resonances below operation speed. The drive is then subject to only minor continuous vibratory torques, protecting and extending the life of your equipment. Rubber elements for the CENTAMAX are available in different degrees of shore hardness. CENTAMAX elements are also offered in higher temperature CENTALAN-HT or silicone if required. This enables easy adjustment of the torsional flexibility of the couplings. Torsional vibrations are damped, and resonance reduced, minimizing the impact on your driven equipment. CENTAMAX is built with overload protection. Under extreme loads caused by torque overloads or generator short circuits, the flexible coupling slips through cogged outer teeth, protecting the engine and surrounding units from overload damage. CENTAMAX includes many plug-in variations for simple assembly with minimal mounting effort. The hubs can be customized to various mounting and application conditions. Built with the highest standards in design and quality, CENTAMAX coupling systems are the reliable choice.

LAMIDISC couplings are suitable for power transmission in hazardous areas. They are certified according to EC Directive 94/9/EC (ATEX 95) and are suitable for potentially explosive atmospheres GROUP II (categories 2G/2D).

We provide turn-key solutions rather than just couplings. With this aim, we offer LAMIDISC couplings in combination with steel or composite drive shafts and other components such as JS nuts, bearings, expansion bolts, etc.

Features and Benefits:

• 6, 8 and 10 bolts design available

• DOM range available for quick assembly

• Wide range with no size limits

• Torsionally rigid and backlash-free

• Superior disc pack profile

• Maintenance free. No need to grease

• No need to disassemble the coupling to inspect. Discs can be checked during operation by using a strobe light

• If properly aligned and used within specification, it should outlive the machine in which it is installed

• Spare disc packs available in stock for immediate delivery

Jaure® marine-style gear couplings have been operating for years in a variety of applications such as main propulsion & maneuvering of vessels, and dredging including underwater use fire fighting pumps, winches, etc.

The Jaure MT couplings can be also delivered on demand with type 3.2 Inspection. Certificate of any marine classification society.

We are additionally awarded with the Manufacturing Survey Arrangement – MSA from DNV. The MSA certificate shows our commitment to continuously improve the service and response time to our customers and remain competitive in the marketplace.

Features & Benefits:

• Jaure® couplings offer maximum torque capacity. This is due to the optimum pitch diameter of the gears, providing reliability.
• High permissible hub bore allows more favorable size selection of the coupling for a certain shaft diameter. This offers an important economic saving.
• High permissible additional loads for starting and short-circuit peak torque.
• Highest gear accuracy and quality thanks to the production improvements obtained with new CNC gear cutting machines and automatic charge systems.
• The design, manufacture, and sale of all Jaure's gear couplings and drive components are integrated into Jaure's Quality System. This is according to ISO 9001 and certified by DET NORSKE VERITAS (DNV).

The main parts of the JHC coupling are the inner sleeve and the outer hub. The fitting surfaces of the sleeve and hub are slightly tapered. By driving the outer hub onto the inner sleeve, it is generated an interference fit with the shaft.

The press fit required for the JHC coupling is defined by the expansion of the hub. It may also be defined by the axial drive-up distance of the hub onto the tapered sleeve.

Dismounting is done in a similar way: the friction between the tapers is overcome by injecting oil.

Features and Benefits:

The main advantage of JHC couplings is its simplicity for mounting and dismounting. This operation can be done without any special tooling or gauge manufactured specially for it and can be carried out in a short period of time. Only a high-pressure oil pump is needed for the mounting and dismounting.

Other advantages:

• No need for heating or cooling of the parts.
• Shaft does not need to have any special shape.
• Due to its specific fitting method, it can be mounted and dismounted several times, without the shafts getting worn.
• Easy to adjust to its desired position before mounting it, by rotating and/or moving axially.
• Thanks to its engineered design, stresses are uniformly spread when transmitting the torque. The whole contact surface between parts transmits torque.
• Can withstand high shock load
