2635820281 Atlas Copco OEM Drive Coupler

The 2635820281 Atlas Copco OEM Drive Coupler is a coupling for Atlas Copco rotary blasthole drilling rig platforms. This coupling is specified for select DM-series drilling rigs including the DM-M3, DM-45, DM-50, and DM-L models used in mining and quarry operations worldwide.

Atlas Copco drilling rigs operate under extreme conditions that demand heavy-duty drive couplers. The coupling transmits high torque from the power module to the rotary drive system while absorbing the torsional shock loads that occur when the drill bit encounters varying rock formations. Coupler failure on a drilling rig means an immediate production stop, making proactive replacement during scheduled maintenance a standard practice in mining operations.

The 2635820281 matches Atlas Copco’s OEM dimensional and material specifications. Follow the rig service manual for proper installation, alignment, and torque procedures. Inspect the coupling at every scheduled maintenance interval.
