Coupling sleeves are usually used in extension rod connection, and the function is transmitting the impact energy from the rock-drill piston and the rotation torque into the drill rod without losses. It must bear the shock of up to 6300 blows transmitting from the piston continually. The sleeve greatly enhances endurance and reliability.
The raw material of coupling sleeve produced by XINLE is steel supplied by internationally famous brands and go through precise machining by CNC processing equipment, which makes sure the dimensional precision is optimized.
