xiros xirodur B180 polymer ball bearings

Maintenance-free dry run tribologically optimised polymer xirodur B180 polymer ball bearings are said to guarantee low friction values for the inner and outer bearing ring, and the plastic ball bearing allows high rotational speeds with a limit speed of 1800 rpm.

The xiros end cap ball bearing can be equipped optionally with glass, plastic or stainless steel balls. The balls are housed in a polyamide cage, which guarantees high strength and ductility.

The tribo-polymer xirodur-B180 also makes the end cap ball bearing resistant to chemicals and corrosion, meaning temperatures of between -40 and +80°C can be managed without any malfunctions, even over long periods.

The low weight of between 32.5-25.9 g permits installation even under very low weight requirements, and the axial load-bearing capacity is 245 N in static use and 294 N in dynamic applications.

The end cap ball bearing can be used for a range of applications such as roller conveyors and, since no lubrication is required, unnecessary soiling and the risky use of solvents can be avoided. The ball bearings can be cleaned with water, thus meeting many hygienic and ecological standards. This is important where soiling is not tolerated at all, such as the food or packaging industries.
