Barrel Couplings TNK

Our Barrel Couplings of the RINGFEDER^® TNK series – originating from the proven TSCHAN^® TK product line – have been specifically developed for connecting the gearbox output shaft to the rope drum in crane hoisting applications. The torsionally rigid couplings securely transmit high torques and radial loads via barrel-shaped steel rollers while simultaneously compensating for angular and axial shaft misalignments. Thanks to their articulated operating principle, they compensate for operationally induced deformations and prevent undesirable reaction forces within the drivetrain. High-strength materials, a compact design and an integrated inner cover enable simple installation and maintenance even in confined installation spaces. Advanced sealing systems reliably prevent the ingress of contaminants and the leakage of lubricants, while the integrated wear indicator allows quick and straightforward condition monitoring. Typical applications include crane hoists, lifting platforms, platform hoists and mine winders, as well as other installations where substantial radial loads must be accommodated in addition to high torque transmission.
