Bolt-on hubs provide a reliable, removable connection between a shaft and a rotating component such as a pulley, sprocket, or wheel. The B20 is installed directly onto a shaft using bolts, eliminating the need for keyways or set screws in applications where they are not practical. Weighing 2 pounds and measuring 9.75 inches by 4 inches by 3.75 inches, this hub is sized for straightforward handling and installation by mechanical, HVAC, or industrial service technicians.\u003c\/p\u003e\u003cp\u003eThe B20 bolt-on hub suits residential and light commercial mechanical systems where positive shaft engagement is required. Typical applications include fan assemblies, blower systems, conveyor drives, and similar rotating equipment. It is suited for installations where the hub must be periodically removed for maintenance or component replacement without damaging the shaft surface.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-inch bore size for direct shaft mounting\u003c\/li\u003e\n\u003cli\u003eBolt-on design allows removal and reinstallation without shaft damage\u003c\/li\u003e\n\u003cli\u003eCompact form factor at 9.75 x 4 x 3.75 inches for space-restricted installations\u003c\/li\u003e\n\u003cli\u003eLightweight at 2 pounds for easy single-technician handling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit bolt-on hub for rotating mechanical assemblies requiring a 2-inch shaft interface.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanical or HVAC technician.
