For the safe and comfortable use of the car, the serviceability of every part and mechanism is important, therefore it is very important to regularly check all the elements of the car and, if necessary, immediately replace them. Particular attention should be paid to diagnostics of the chassis, because it is she who is responsible for the vehicle's handling, reliable adhesion to the road surface and smooth running. For safe driving, especially at high speeds, it is important that the wheels are firmly held in place. A hub is used to mount the wheel on the vehicle axle. This means that each wheel is equipped with its own hub, thanks to which its rotation is possible.

The construction of the TOPRAN brand Wheel Hub

Since this part must withstand the weight of the entire vehicle and work under increased loads, especially when driving on bad roads, it is made by turning from a solid steel billet. The hub has a rather simple structure - it is a round-shaped and small-sized part with special holes: a central one of a special configuration and for attaching suspension elements.
