Industrial ATRA-FLEX A1-COUPLING-HUB-38MM is a Size A1 hub for A-Series jaw couplings in the ATRA-FLEX family, configured for a 38 mm coupling configuration. It serves as the shaft-hub component of a jaw coupling assembly, transmitting torque while enabling limited angular and parallel misalignment when paired with the matching elastomer insert and coupling components. Designed for use with ATRA-FLEX A-Series assemblies, this 38 mm hub integrates into 38 mm-class drive configurations to enable reliable torque transfer in mechanical drive systems.
