In many cases, xiros® ball bearings made of high-performance plastics are more economically efficient than ball bearings made of metal. the polymer ball bearings not only cost up to 40% less but are also 60% lighter than their equivalent made of metal. They also help to ensure a long, low-maintenance machine life. The reason is that xiros® ball bearings enable dry, low-friction operation without a single drop of lubricating oil. The xiros® portfolio is growing continuously, bringing forth new bearing types, sizes and combinations of materials.
xiros polymer ball bearings to DIN 625 do not need any additional lubrication, are corrosion-resistant (if glass or plastic balls are used) and, during operation, are extremely quiet. This makes them a cost-effective alternative to metal ball bearings. Made from a mixture of tribo-polymers, the xirodur polymer components are light, resistant to chemicals and non-magnetic. This ensures that they can be used safely in the areas of medicine, food processing, drive technology etc.
The plastic of our xiros ball bearings consist of a mixture of standard polymers, solid lubricants, fibres and filaments, whereas the balls are typically made of glass, plastic or stainless steel. The balls are located in a cage, which can consist of our own xirodur B180 material, polyamide (PA), polypropylene (PP) or polyetheretherketone (PEEK). Please see our catalogue to find further combinations of materials in addition to technical specifications.
