Falk 1020T31 Shaft Hub 0.875 Bore 3/16 x 3/32 KW

Falk 1020T31 Shaft Hub offers a precise 0.875 inch bore and a 3/16 inch by 3/32 inch keyway, providing a keyed connection between a shaft and a matched pulley, gear, or sprocket. This shaft hub is used to mount drive components onto a shaft in power-transmission systems, enabling secure torque transfer while maintaining accurate alignment. The bore size defines the shaft diameter accepted by the hub, and the keyway enables a key to lock the mounted part to the shaft, distributing torque along the key and preventing relative motion under load. The 1020T31 designation identifies the Falk sizing and fit, supporting compatibility with other Falk catalog parts that use the same interface standards. In practical terms, selecting a hub with these exact dimensions helps ensure that replacement parts fit the system without modification, minimizing downtime during maintenance or upgrade of equipment that relies on keyed hub connections. Built for reliability in industrial drive trains, this Falk shaft hub combines straightforward installation with a robust interface, making it a common choice when a keyed hub is required for a precise, repeatable drive system.
