Overview
The Falk 1040T31 is a finished-bore steel shaft hub for steelflex grid couplings. This component is engineered as part of Rexnord’s industry-leading Falk Steelflex coupling line, combining the high torque capacity of gear couplings with the torsional flexibility and low-maintenance characteristics of elastomeric designs. The 1040T31 hub accommodates a 1.125″ shaft bore and integrates into flexible coupling assemblies for smooth, efficient power transmission across diverse industrial sectors.
