Overview
The Dodge PX120 3020 Taper-Lock Flange Assembly Coupling (MPN 010608) is an elastomeric para-flex coupling flange designed for critical industrial power transmission and motion control applications. This flange assembly features a cast iron construction with a 12.375-inch outside diameter, 2-inch bore length, and accommodates standard 3020 taper-lock bushings. The coupling is engineered with a patented cording that transmits torque, offers a wear indicator, and absorbs shock loads to prevent damage to connected equipment.
