  • Series X Flexible CouplingsBenzlers

    The Elflex range of pin and bush couplings are ideally suited for applications where a limited amount of misalignment of the shaft is unavoidable. Elflex flexible couplings are cushioned drive type couplings which transmit the torque through rubber bushes which have an excellent capacity to absorb shocks. The Elflex range is available in 26 sizes.
