the central part of a wheel where the axle is housed, allowing the wheel to rotate freely
A hub is the central part of a wheel where it attaches to the vehicle. It connects the wheel to the axle and allows it to rotate smoothly. The hub also contains parts that help reduce friction and make the wheel turn efficiently. In addition to supporting the wheel, the hub often has bolts or fasteners that hold the tire in place.
