Rexnord 1080-T Shaft Hub for 1.875 Inch Bore With Keyway

Rexnord 1080-T Shaft Hub for a 1.875 in bore is a finished-bore hub in the Falk Steelflex grid-coupling family, designed to mount to a 1.875 in shaft and provide a keyed connection for torque transmission. This specific 1080T hub variant is sold as non-stock under part number 0704651. The hub follows the standard T-series grid-coupling design with a 0.750 x 0.375 in keyway and a 1.875 in bore, fitting into a finished-bore configuration for reliable torque transfer. For reference, the 1080T family lists a T-Hub length around 3.937 in and a shaft-hub length around 4.062 in, indicating a relatively long hub suitable for robust couplings. This hub is intended for Rexnord Falk Steelflex grid couplings, providing compatibility with the T-series components and serving as a precise extension hub to mate the motor shaft with the grid-coupling assembly.
