Elastomer Jaw Couplings TNB
High-strength elastomer jaw couplings of the proven TNB series—formerly known as TSCHAN TNB—are globally recognized for their superior durability and functionality in the most demanding heavy-duty applications, ensuring maximum operational reliability for the machines and plants of their users. These puncture-proof and torsionally flexible couplings effectively compensate for axial, radial, and angular shaft misalignment, and they demonstrate exceptional robustness even in the most challenging environmental conditions, such as extreme temperatures or heavy dirt and dust. As a result, they are predominantly used in steel mills, rolling mills, cement plants, mining and construction machinery, including bucket wheel excavators, shredding facilities, and tunnel boring machines, as well as in offshore technology. Torque is transmitted via pressure-loaded, oil-resistant elastomer buffers made of high-quality Perbunan or Polyurethane, which also absorb process-related shocks and cushion dynamic effects caused by the acceleration of heavy masses. This design shifts harmful torsional vibrations from the operating range of plant machinery to rotational speed ranges where they have no adverse effects. The TNB heavy-duty couplings can be used in any direction of rotation and installation position, and thanks to their modular design, they are available in a wide range of standard and specialized variants.
