The term 'Wheel Center' is composed of two words, 'HUB' and 'NAVE'. The HUB is the center of a wheel, usually made of metal, and is the part that connects the wheel to the axle. The NAVE is the central part of a wheel, usually made of wood, and is the part that supports the spokes. Together, the HUB and NAVE form the Wheel Center, which is the core of a wheel and provides the structure and strength for the wheel.
