DM Moment Couplings

Dodge Moment couplings are specifically designed to make the rigid connection between the output shaft of a gearbox and driven equipment.  Highly engineered to meet the most rigorous application requirements, Dodge Moment couplings are capable of handling both the required application torque and the bending moment forces of the suspended weight of a drive package – including the gearbox, motor, high-speed couplings, and swing base.  Utilizing high-strength 4140 alloy steel and Grade 8 bolts, this robust design allows for an alignment-free drive by eliminating the time consuming process of aligning the gearbox assembly to the head pulley shaft.
