Elastomer Jaw Couplings TNB

Elastomer Jaw Couplings of the RINGFEDER^® TNB series, formerly TSCHAN^® TNB, are designed for the secure transmission of maximum torques in extremely demanding heavy-duty drives. Their robust jaw design provides high resistance to breakage, while compression-loaded, radially accessible elastomer buffers made of Perbunan or polyurethane effectively dampen process-related shocks and torsional vibrations. At the same time, the torsionally elastic and fail-safe couplings compensate for axial, radial and angular shaft misalignments and protect connected drive components against dynamic loads. Typical fields of application include ore extraction and processing, mining and construction machinery, steel and cement plants, material handling systems, and offshore technology, particularly where large masses must be accelerated and loads fluctuate significantly. The modular portfolio includes one-piece and multi-piece hubs, versions with brake discs, and solutions for short shaft distances, while covering nominal torques of up to 260,000 Nm. Individually replaceable radial buffers and removable center sections simplify installation and maintenance, reduce downtime, and support high system availability.
