Overview
The Falk 251672 Steelflex Grid Coupling Hub is a precision-engineered shaft hub for the 1040T31 size Steelflex grid coupling. Manufactured by Regal Rexnord, this hub features a straight rough stock bore (RSB) design with a small through hole, allowing it to be custom-bored to match your equipment’s shaft diameter. Falk 251672 units are widely used in motor-pump applications and other industrial power transmission systems requiring torsional flexibility and shock absorption.
