Plastic ball bearings: xiros®

xiros plastic ball bearings according to DIN 625 are often a better alternative to metal ball bearings. Compared to their metal equivalents, they are lubrication-free, lighter and have a longer service life. The maintenance-free plastic ball bearings have already proven themselves in many applications. The xiros service life calculator helps you find the suitable ball bearing for the most specialised applications.

Advantages xiros ball bearings

Selected plastic ball bearing application examples

Extremely smooth running

Instead of metal ball bearings, this labelling machine uses plastic ball bearings in up to 36 guide rollers, ensuring an uninterrupted operation.

Excellent coefficient of wear

No more downtimes

This mobile bike wash system uses two igus slewing ring ball bearings for the bearings of the washing brushes, which work without problems despite difficult conditions.

Lowest rolling friction

Long service life

Despite being used under water, the plastic radial ball bearings installed work without failures. This is due to their self-lubricating and corrosion-free properties.  

Reliable cleaning

High temperature resistance

Despite the most difficult conditions, igus radial ball bearings work in this mechanical drive unit of a pellet stove, which is responsible for the electricity-free transport of pellets into the combustion chamber.  

Long-term smooth running
