R51 Length 180mm Thread Drill Rod Coupling sleeves

Coupling sleeves, other name is Coupling, when using rock drills with male shank adaptersand 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 sleeveSmall non-threaded bridge in the centerSteel cannot thread past bridge areaSmaller diameter steel end portions fit together in the centre bridge area of the couplingSemi-bridged couplings are most suited to high torque machinesMost rope and T threaded couplings are semi-bridged

Full-Bridge Coupling sleeveEliminates the potential for the coupling to creep along the threaded jointsTypically used in surface applicationsBetter uncoupling characteristics and tend to maintain tighter jointsLess chance of jammingBest suited to machines equipped with independent rotation
