Indication of tread hardness

The hardness of the tread is stated on the product pages in Shore. A distinction is made between Shore A for elastomers and polyurethanes and Shore D for hard plastics. Shore hardness is tested by the sticking a spring-loaded pin made of hardened steel into the test material. The scale runs from 0 to 100 Shore. 0 Shore corresponds to a penetration depth of 2.5 mm, while for 100 Shore the penetration depth is 0 mm. The higher the number, the harder the material.

The Shore A method uses a needle with a blunt tip and the Shore D method uses a needle with a spherical tip which is applied at a 30° angle. Since the hardness depends on the temperature, the measurement is carried out at a temperature of 23 °C ± 2 K in accordance with the standard.

In addition to soft and hard rubber wheels, our range includes a hybrid wheel: The hybrid wheel has a hard polyamide tread and soft rubber center. This combines the properties of a hard wheel with the cushioning effect of softer wheels.
