jbj Techniques Limited
Torsionally flexible pin and bush couplings and changing loads are no problem for robust, compact flexible RUPEX (R) couplings. The steel variant is especially suitable for high-speed drives. RUPEX (R) couplings are fitted by putting together the coupling halves. Fitting with low torsional backlash is simplified by the barrel-shaped geometry of the buffers. RUPEX (R) couplings require little maintenance. Only the elastomer elements, as wear parts, need be replaced and the coupled machines need not be moved to do so. RUPEX (R) couplings...
