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.
