We produce flexible and rigid versions of our copper connections. Which connection would you like us to create for you? Flexible braids made from round or flat copper conductors are the optimum solution to link electrical connections subject to mechanical vibration. Different conductor cross-sections with tinned ends or crimped and punched ferrules, with insulation or bare: our customers determine the composition of our huge variety of products. At MACK we also produce rigid connections made of solid copper precisely to your specifications. Precision-made and with exact forms and curves, they fit perfectly into the respective installation position. And it goes without saying that even here we can create partially insulated solutions.

One-part design with VKW buffers for highest torque transmission The TSCHAN ® TNB BH coupling is a torsionally flexible, puncture proof claw coupling. It compensates for angular, radial and axial shaft misalignments within defined limits. The coupling transmits torque through elastic buffers loaded in compression.

The coupling is suitable for use in every direction of rotation and installation position. TSCHAN ®-TNB Type BH One-part design with VkW buffer for highest torque transmission. Easy replacement of the elastic buffer without axial movement of the coupled machines.

Multi-part design with brake drum according to DIN 15431 The TSCHAN ® TNM GBT is a torsionally flexible and shock-proof claw coupling with brake drum and removable claw ring. They compensate for angular as well as radial and axial shaft misalignment within fixed tolerances. The torque is transmitted through an elastic transitional ring. The elastic transitional ring made of Perbunan (Pb) with nitrile rubber as the base material dampens shocks and torsional vibrations, is oil-proof, insensitive to temperature and normally electrically conductive. This prevents undesirable static charging, among other things. The coupling can be used for either direction of rotation and be installed in any position. One coupling half consists of a hub and a bolt on claw ring, for easy separation of the coupled machine. With the claw ring unbolted and slid back, a check of the rotational direction of the drive is possible. In the same manner, a coupling half with the associated aggregate can be...

Multi-part design, elastic ring can be replaced without having to axially move the machine The coupling TSCHAN ® TNM G is a torsionally elastic and puncture-proof claw coupling. It balances out angular, radial, and axial shaft misalignments within defined limits. The coupling transfers the torque via pressure loadable, elastic buffers or Perbunan (Pb) which are joined together as an intermediate ring. The elastic intermediate ring can cushion impacts and torsional vibrations; it is oil-tight and electrically conductive. A coupling half is divided in two and allows through this a simple separation of the coupled machine. With the claw ring pulled back it is possible to check the rotational direction of the drive. It is also possible to lift out radially a coupling half with accompanying aggregate. The elastic intermediate ring can be changed without axially shifting the machine. The coupling is usable in every sense of rotation and installation position. TSCHAN ® TNM G Multi-part...

The slit versions are useful in applications requiring the bridging of bigger tolerances and/or higher torques. Stacking of the elements is not recommended. Characteristics Customized application – by varying the number of Locking Elements, size and quantity of clamping screws, the connection can be adapted to fit most applications concerning surface pressures, materials, hub/shaft dimensions and available mounting space. Transmission of high loads – to increase the transmissible torque and axial forces up to 4 Locking Elements can be used in series. Maximum reliability – no matter whether the connection is subjected to static, pulsating, dynamic or intermittent loads. Simple manufacture – shaft and hub are designed without keyway. Apart from this, relatively large tolerances are admissible. Easy adjustability – Locking Elements work without positive connection. So they can be adjusted at any place to any position by following the simple installation and removal...
