Overview
The Falk 0744097 1050T31/35 spacer hub is an individual hub component for T31/T35 series spacer-style grid couplings. Steelflex spacer hubs like this one are engineered to span the DBSE (distance between shaft ends) in spacer couplings, providing flexible power transmission with misalignment compensation. This component is manufactured with precision tolerances and steel construction, meeting OEM specifications for industrial machinery requiring reliable torque transmission and damping.
