The term 'Hub Connection' is a type of AXLE connection that is used to connect two or more axles together. It is a mechanical device that is used to transfer power from one AXLE to another, allowing for the rotation of multiple axles at the same time. The hub connection is typically made of metal and is designed to be strong and durable. It is commonly used in vehicles, such as cars, trucks, and trailers, as well as in industrial machinery.
