Frequently asked questions about this product
The higher the load, the higher the Shore hardness should be. We will be happy to advise you.
The difference lies in the type of sealing. ZZ ball bearings have two metal shields that protect the balls from coarse dirt and are particularly suitable for applications with little contamination. 2RS ball bearings, by contrast, have two contact rubber seals that offer significantly better protection against moisture, dust and dirt. This makes them particularly suitable for more demanding operating conditions. We will be happy to advise you personally on which version is right for your application.
Colour changes in VU rollers are due to the material and do not constitute a quality defect. The raw material Desmodur 15 contained in Vulkollan can discolour when exposed to UV light. This discolouration affects neither the technical properties nor the load capacity or service life of the roller. Rather, the characteristic colour change is considered a typical feature of the material Vulkollan.
