xiros® polymer ball bearings open up new application areas for plastic roller bearings. After the 2007 market launch, the life-time of the high-temperature option with xirodur® A500 inner and outer rings could be significantly raised by up to
factor 5.

xirodur® A500 polymer ball bearings in combination with a PEEK cage and glass balls are often used in environments where high chemical resistance is required and stainless steel components should be avoided entirely.

xirodur ® A500 polymer ball bearings in combination with a PA cage and stainless steel balls are the economic alternative in the xirodur ® A500 range, when only a temperature resistance up to +150°C is required and no chemicals are used.

Polymer ball bearings made of xirodur® A500 are also available with plastic balls. At low loads, the wear resistance can thus be improved by up to a factor of 3.
