Alloy Steel Speed / Drifting Drill Rod Crossover Coupling Sleeve For Connecting Extension

Description

JC Threaded coupling sleeve is made of high quality of alloy steels and CNC machining guarantee our reliable and consistent quality control of coupling sleeves.Both semi-bridge and full-bridge coupling sleeves are manufactured by us in different sizes as below:

Thread sizes: R22, R25, R28, R32, R35, R38, T38, T45, T51;
Two catagories: Standard coupling sleeves, adapter(crossover) coupling sleeves;

Semi-bridge coupling, by far is the most popular, has a small non-threaded bridge in the centre. The drill rod cannot thread past the centre of the couplings, and the smaller diameter rods portions butt together in the centre bridge area of the coupling. Semi-bridge couplings are most suited to high torque machines. Most rope (R) and Trapezoidal (T) threaded couplings are semi-bridged.

Full bridge coupling has a great advantage that it positively eliminates the potential for the coupling to creep along the threaded joints. These couplings, are typically used in a Trapezoidal thread, in surface drilling application, have better uncoupling characteristics and tend to maintain tighter joints. Full-bridge couplings have less chance of jamming and are best suited to machines equipped with independent rotation.

Adapter couplings are used when changing from one thread type, or size, to another and are typically required only in special circumstances.
