    T45-210mm Threaded Drill Rod In Rock Drilling / Mining Coupling Sleeve T38-190mm

    Product Description
    Coupling 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.

    Rock drilling tools: Adapter Coupling, Cross-over Adapter Coupling, coupling sleeves
    Used when changing from one thread type, or size, to another and are typically required only in special circumstances

    Thread sizes: R22, R25, R28, R32, R35, R38, T38, T45, T51;
    Two catagories: Standard coupling sleeves, adapter(crossover) coupling sleeves;

    Semi-bridge coupling, by far is the most popular, has a small non-threaded bridge in the centre. The drill rod cannot thread past the centre of the couplings, and the smaller diameter rods portions butt together in the centre bridge area of the coupling. Semi-bridge couplings are most suited to high torque machines. Most rope (R) and Trapezoidal (T) threaded couplings are semi-bridged.

    Full bridge coupling has a great advantage that it positively eliminates the potential for the coupling to creep along the threaded joints. These couplings, are typically used in a Trapezoidal thread, in surface drilling application, have better uncoupling characteristics and tend to maintain tighter joints. Full-bridge couplings have less chance of jamming and are best suited to machines equipped with independent rotation.
