    cupling sleeves, other name is Coupling, when using rock drills with male shank adapters

    and a conventional drifter rod, a coupling is required to join the adapter to the rod, ensuring the ends touch for efficient energy transmission. Couplings are also used to connect several rods to each other in the same way. Couplings have a middle stop to prevent over-threading on to the drill rod. We can manufactures   semi-bridge, full bridge coupling sleeves for the percussive tools.

    Semi-Bridge Coupling sleeve

    Small non-threaded bridge in the center

    Steel cannot thread past bridge area

    Smaller diameter steel end portions fit together in the centre bridge area of the coupling

    Semi-bridged couplings are most suited to high torque machines

    Most rope and T threaded couplings are semi-bridged

    Full-Bridge Coupling sleeve

    Eliminates the potential for the coupling to creep along the threaded joints

    Typically used in surface applications

    Better uncoupling characteristics and tend to maintain tighter joints

    Less chance of jamming

    Best suited to machines equipped with independent rotation (i.e., S36IR rock drill)
