Rock Drilling Rig T38 T45 T51 GT60 Coupling Sleeves for Mining Rock Drilling Coupling sleeve

 

 

Thread R38 T38 T45 T51 Coupling Sleeves for Bench Drilling , High Wear Resistance



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.

 

 

Couplings sleeve are used to well connect the shank adapter to the drill rods or well contact two extensionrods for transmitting energy. It has standard type coupling and crossover coupling.
