The 2650456383 Atlas Copco OEM Drive Coupler is a coupling for Atlas Copco drilling rig platforms.
Atlas Copco drilling rigs including the DM-series (DM-M3, DM-45, DM-50, DM-L) operate under extreme conditions – high rotational loads, constant impact from rock contact, abrasive dust, and wide temperature swings. The drive coupling in these rigs must transmit substantial torque from the power module to the rotary drive system while absorbing torsional shock loads that occur during drilling operations.
The 2650456383 is a direct OEM replacement matching Atlas Copco’s dimensional and material specifications. Follow the rig manufacturer’s alignment and torque procedures during installation. Inspect the coupling at every scheduled maintenance interval given the severity of drilling rig operating conditions.
