Industrial 117-022-976 Pulley Hub

The FLANGE 117-022-976 Pulley Hub (50mm Bore) is an industrial drive hub that mounts pulleys onto 50 mm shafts for torque transfer and rotational drive in belt-and-pulley transmission systems. Flange-mounted for a secure pulley-to-shaft connection in continuous-duty mechanical power transmission, the hub uses high-strength cast steel or ductile iron depending on the OEM configuration and accommodates a 50 mm bore. The hub is typically keyed (verify shaft key size per application) and installed by press-fit or keyed shaft mounting with set screws or clamping (design dependent). It is commonly used in conveyor drive systems, industrial belt drives, packaging machinery, agricultural equipment, and OEM drive assemblies, providing a reliable interface between shaft and pulley for efficient torque transmission in industrial mechanical power transmission systems.
