R32 160mm Threaded Crossover Coupling Sleeve Drill Pipe Rod
Coupling
Product Description:
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 |
