Zirconium ores - Import export

Our all-ceramic bearings are characterised by their high corrosion resistance to seawater and various chemicals. They are therefore used, for example, in the chemical industry, in the food and beverage industry, in shipping and in chlorine systems. We can manufacture our full ceramic ball bearings with rings and balls made of zirconium oxide (ZrO2) or silicon nitride (Si3N4), depending on the application. They are available with full balls or with cages made of PEEK or PTFE. The runout accuracies common with precision steel bearings cannot be achieved with all-ceramic bearings, so speed values have to be reduced. Ceramic materials are harder than steel, but also more brittle. Silicon nitride in particular has a low elongation at break and tends to break under tensile stress without prior plastic deformation. We take this into account when selecting the optimum bearing solution for your specific requirements.
