Shank Adapters and Coupling Sleeves

We will reply in 24 hours.

 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.

Specification and function of the coupling sleeve:
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.
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 
Same diameter 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.
