Product Description

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.
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

Performance

High strength chromium-molybdenum steel with high fatigue strength and excellent wear resistance

Application

Used in benching and long hole drilling.
