Resistance

The selection of a suitable material according to the respective appplication is decisive for an optimum function of the machine element (rolling bearing/linear guide).

Plastics have different mechanical and chemical properties, which are due to the chemical structure of the respective plastic.

In the field of plastics, a basic distinction is made between thermoplastics, thermosets and elastomers. Thermoplastics are mainly used in the manufacture of plastic ball bearings.

The property profile of a plastic is described in the data sheet/safety data sheet of the respective manufacturer. There, information is given on the bulk density, mechanical properties such as tensile strenght, elongation at break, modulus of elasticity, etc. , electrical, thermal and optical properties, as well as information on the water absorption of a material (hydrophilic / hydrophobic materials). The property profile of the used plastic is transfered to the prefabricated part.

In addition to the property profile of a plastic, resistance also need to needs also be considered. Resistance includes resistance to a wide variety of media (liquid), temperature resistance, resistance to radiation, etc.

Internationally recognised databases, for plastic parameters, can be used to determine the suitable plastic for each requirement profile. They provide guidelines. The long-term properties in the application area must be considered on a case-by-case analysis.

We shall be pleased to advice you on the selection of a suitable plastic !
