T38 T45 T51 Drill Threaded Coupling Sleeve Mining Equipment Accessories

Coupling sleeve also called 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.

Function: Coupling sleeve,Adapter Coupling

Type: Full-bridge,Semi-bridge, same/different diameter coupling

Suitable for top hammers and drifter from Atlas Copco, Tamrock,Furukawa,Ingersoll Rand,etc.

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.

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.
