The wheel body

Wheel center material

A wheel center can be made of sheet steel, plastic or cast metal, for example. The versions made of sheet steel consist of two wheel rims which are joined by riveting or flanges. Unlike the models made of plastic, these wheel rims only form a unit in combination with the rubber tire and the bearing. Plastic wheel centers are subdivided into different versions, and can be made of, for example, polyamide, polypropylene or polyethylene.

The cast metal wheel centers are also subdivided: Versions made of aluminum, malleable cast iron or die-cast zinc are possible. Their properties are low wear and tear, break-proof and shock resistant, for use on problematic floors and surfaces. The cast metal versions are produced with solid rubber tires or a vulcanized-on rubber tire.

Wide variety of wheel center profiles

A wide variety of profiles can be used for the wheel center. The profile used depends on numerous factors. The most important of these are the size of the wheel, the wheel center material, the desired tire cross-section and the tread material. The type of application and the required load capacity of the wheel also play an important role.

The selection also depends on various technical parameters to ensure the wheel meets all of the requirements. This may mean, for example, that the resilience of the tires must be taken into account and overstretching must be avoided. This ensures smooth operation.
