Overview
The Falk 1040T RSB 246654 is a precision-engineered hub coupling from the Steelflex grid coupling family. This straight bore, rough stock bore (RSB) hub is designed for the T10/T20 series and provides flexible torque coupling with torsional damping. The 1040T RSB 246654 combines the high torque capacity of a gear coupling with the shock-absorbing benefits of an elastomer coupling, making it ideal for demanding industrial drive applications.
