Our xiros® plastic ball bearings

The rust-proof alternative to metal ball bearings

xiros® plastic ball bearings according to DIN 625 require no lubrication, are corrosion-free (when using glass or plastic balls) and operate extremely quietly. This makes them a cost-effective alternative to metallic ball bearings. Made from a mixture of tribopolymers, the iglidur® material plastic components are light, resistant to chemicals and non-magnetic. This ensures safe use in medicine, packaging, food processing, drive technology and many other industries. Whereas the plastic of our xiros® ball bearings consists of a mixture of basic plastics, solid lubricants, fibres and filaments, the balls are typically made of glass, plastic or stainless steel. The balls are housed in a cage, which can consist of our own xirodur B180 material, polyamide (PA), polypropylene (PP) or polyether ether ketone (PEEK).

Frequently asked questions about xiros® plastic ball bearings.

What are ball bearings?

Ball bearings belong to the family of rolling bearings. Moving between an inner ring and an outer ring, rolling bodies reduce rotational friction and absorb radial and axial loads. Because the balls roll, they have a much smaller coefficient of friction than two flat surfaces that slide against each other. Due to the smaller contact surface between balls and rings, the ball bearings tend to have a lower load capacity for their size than other kinds of rolling bearings.

What advantages do the xiros® plastic ball bearings have over other ball bearings? 

Xiros® plastic ball bearings are lubrication and maintenance-free. They are lightweight, corrosion resistant and have a high media resistance.

Where are xiros® plastic ball bearings used?

There are lots of applications and industries that xiros® ball bearings are used, labelling machines, food and packaging and conveyors.
