FALK 0788452 HUB 1090T 2.1875 Inch Bore With Keyway Shaft Mount

FALK 0788452 HUB 1090T is a shaft-mount hub from Falk, featuring a 2.1875-inch bore and a keyway to lock the hub to a shaft. The 0788452 designation identifies this specific hub, with the 1090T marker indicating its product designation in the catalog. This component is intended for mounting directly onto a shaft as part of a mechanical drive arrangement, where the keyed bore provides positive torque transmission and resists slippage between hub and shaft. The bore size defines the inner diameter that must match the mating shaft, while the keyway accommodates a matching key to secure rotational alignment. As a purpose-built hub, it supports accurate positioning and reliable torque transfer in assemblies that rely on a shaft-driven connection. With its shaft-mount configuration, this Falk hub serves as a foundational element in attaching rotating components to a drive shaft, ensuring consistent performance in systems designed around direct-drive or belt-driven power transmission.
