The 2636783710 Atlas Copco OEM Drive Coupler is an OEM coupling for Atlas Copco DM-series rotary blasthole drilling rigs including the DM-45, DM-50, and DM-L. This heavy-duty coupling handles the extreme torque demands of rotary drilling in mining and quarry operations.
Atlas Copco drilling rigs operate in some of the harshest conditions in the mining industry. The drive coupling transmits torque from the power module to the rotary head while absorbing the torsional shock loads that occur when the drill bit encounters varying rock formations. A failed coupling shuts down drilling production immediately, making proactive maintenance essential.
The 2636783710 matches Atlas Copco’s OEM specifications. Follow the rig service manual for installation, alignment, and torque procedures.
