Ceramic balls - Import export

Zirconium oxide-based ceramic beads type WIWOX® KM specially developed for shot peening and surface finishing. The high fracture toughness and surface smoothness of the ceramic beads allow the production of extremely smooth surfaces.

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.

Our KIS hybrid bearings combine the best of two worlds - the robustness of classic rolling bearings (or stainless steel bearings) and the efficiency of state-of-the-art materials. With an optimised combination of high-quality steel rings and precise ceramic balls, our hybrid bearings offer outstanding strength and durability. Rolling elements made of ceramic offer a current-insulating property. These hybrid bearings have the same dimensions as comparable all-steel bearings and can significantly improve the reliability and robustness of machinery and equipment. In particular, they show their advantages in applications where the bearings are confronted with contamination from abrasive particles, insufficient lubrication, vibrations or current passage. At KIS, we optimise our materials for hybrid bearings to ensure flawless performance in applications under critical conditions at all times.
