The 35703750 Ingersoll Rand OEM Drive Coupler is an OEM coupling for Ingersoll Rand DM-series rotary blasthole drilling rigs including the DM-45, DM-50, and DM-L. This heavy-duty coupling handles high-torque power transmission in mining and quarry drilling operations.
Drilling rig couplers operate under extreme conditions – sustained high torque, impact loading from rock contact, abrasive dust, and wide temperature swings. The 35703750 transmits torque from the power module to the rotary drive system while absorbing torsional shock loads that occur during drilling.
This is a direct OEM replacement. Follow the rig service manual for alignment and torque procedures. Inspect at every scheduled maintenance interval.
Stark Industrial Products supplies drilling rig couplers with expedited shipping to mine sites.
