Coupling SleeveCoupling 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.Coupling
sleeves are also used to connect several rods to each other in the
same way. Coupling sleeves have a middle stop to prevent
over-threading on to the drill rod.Thread: R22, R25, R28, R32, R38,
T38, T45, T51Function: Coupling sleeve, Adapter CouplingType:
Full-bridge, Semi-bridgeSuitable for top hammers and drifter from
Atlas Copco, Tamrock, Furukawa,Ingersoll Rand, etc.Used in
extension rod connection, its function is to transmit impact energy
from the rock-drill piston, as well as rotation torque, into the
drill string with no losses. It must withstand and transmit up to
6300 blows per minute from the piston continually, with great
endurance and dependability.(1) Size:
