The Yale 501055200 Coupler is an industrial-grade mechanical coupling that transmits torque between rotating shafts in Yale forklift drivetrains and other material-handling equipment. It is an inline shaft connection (application dependent) built as an industrial-grade metal coupling assembly, designed for high-load, continuous operation in drive assemblies, hydraulic connections, or motor-to-component linkages where alignment and vibration damping are critical for consistent power transmission. Common replacements include Yale 399976460, 220002069, and 220017954.
