Gear coupling - Import export

TNZ ZCA: Double engagement design with integrated O-ring seal The TSCHAN® TNZ ZCA coupling is a torsionally stiff gear coupling designed to have some backlash and consists of two coupling halves that are connected by fitted bolts. TNZ ZCB: Double engagement design with a bolt-on O-ring carrier for ease of installation Unlike the TNZ ZCA coupling, the TNZ ZCB comes with a bolt-on O-ring carrier which facilitates installation by changing the mounting sequence. For mounting the coupling, unscrew the cover and place it on the shaft. Mount the hub onto the shaft, slide the sleeve onto the hub and fasten the O-ring carrier to the sleeve. This way of mounting is advantageous when large couplings are involved.
