ENEMAC safety couplings, also known as torque limiters, are mechanical components that actively protect drives from overload. They prevent malfunctions—such as blockages or foreign objects—from causing damage to gearboxes, motors, or downstream drive components. At the same time, they ensure backlash-free torque transmission, compensate for misalignment, and, depending on the coupling type, can also dampen vibrations.

Today's automated production lines must operate continuously with maximum process stability. Every unplanned downtime causes costs – especially in industries with high plant availability and cycle-critical processes. Safety couplings separate the drive and output sides within milliseconds when a predefined torque is exceeded. To do this, a spring presses balls into calottes in a form-fitting manner. If the set limit torque is exceeded, the balls overcome the spring force and the connection is released. Power transmission stops immediately and rotating masses run freely. Once the fault has been rectified, the elements automatically re-engage – with ENEMAC, this is achieved with precise 360° synchronous engagement. The purely mechanical mode of operation ensures maximum operational reliability, even in the event of power failures or control errors and effectively protects drives and gearboxes from consequential damage.

ENEMAC safety couplings for direct or indirect drives reliably secure torques from 0.3 Nm to 23,000 Nm and can be used at temperatures ranging from a minimum of -30 °C to a maximum of 200 °C. The shaft connection is made by means of clamping hubs, keyways, or conical bushings.

Safety couplings protect drives in filling and packaging systems in the food and beverage industry, in general mechanical and plant engineering, in special machine construction, in test benches, and in the process industry.

ENEMAC shaft couplings are backlash-free compensating couplings for the precise, angle-accurate transmission of torques from 0.4 Nm to 65,000 Nm. Depending on the series, they can be used at speeds of up to 57,000 rpm and temperatures of up to 350°C. Thanks to the wide variety of designs, ENEMAC offers the technically appropriate coupling design for almost every machine – from high-precision axes in machine tool construction to automation, packaging technology, measurement and testing technology, pump systems, energy systems, steel and hot operating applications.

Metal bellows couplings from ENEMAC are completely backlash-free, have high torsional stiffness, extremely low restoring forces, and are therefore particularly suitable for precise positioning tasks and high-load changes in direction of rotation. They enable uniform and controllable power transmission.

Elastomer couplings dampen vibrations and shocks and can effectively prevent resonance from reaching the drive. They are electrically insulating and can be precisely adapted to the required machine characteristics using different Shore hardnesses. They are economical to use, robust, and easy to install.

Disc couplings transmit high torques in a compact design, offer high torsional stiffness, are maintenance-free, extremely durable, and ideal for heavy-duty applications in mining and foundries.

Since 1981, ENEMAC has stood for technical coupling solutions with high operational reliability, long service life, and absolutely reliable repeatability. Every designer thus receives a solution that is precisely tailored to the actual load and technically sound—no compromise.
