R32 160mm Threaded Crossover Coupling Sleeve Drill Pipe Rod Coupling
Coupling sleeve,called coupling too,using connect extention rod and shank adapter.We can produce semi-bridge and fully-bridge according to your requirement.
The connecting sleeve is mainly used for the shank and the drill rod and the drill rod and the connecting rod is connected between the. For reducing the connecting sleeve and the connecting sleeve with the same diameter. Main specifications R32, T38, T45, T51 reducer connected set of R25-R32, R28-R32, R32-R38, R32-T38, R32-T45, T38-T45 and, due to the need of energy transfer and handling, on the material properties and processing technology of higher requirements, connecting sleeve of my company's production, the high quality alloy steel forging processing into, the thread processing the special machining center, high machining precision, with good thread and prolong the prolonging the service life of the connecting sleeve.

![]() | Semi-Bridge Coupling Small non-thread bridge in the center Steel cannot thread past bridge area Smaller diameter steel end portions fit together in the center bridge area of the coupling Semi-bridge coupling are most suitable to high orque machines |
![]() | Full-Bridge Coupling 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 |
![]() | Adapter Coupling Used when changing from one thread type, or size, to another and are typically required only in special circumstances |
