xiros xirodur B180 polymer ball bearings

xiros xirodur B180 polymer ball bearings are designed to be maintenance free and dry running. They are made from tribologically optimised polymers, providing low friction values that allow high rotational speeds with a limit speed of 1800 rpm.

The cap ball bearing is resistant to chemicals and corrosion, meaning temperatures of between -40 and +80°C can be managed without malfunctions, even over long periods.

The low weight of between 25.9 - 32.5 g permits installation even under very low weight requirements.

The axial load-bearing capacity is 245 N in static use and 294 N in dynamic applications and the end-cap ball bearing can be equipped optionally with glass, plastic or stainless steel balls. The balls are housed in a polyamide cage, which provides high strength and ductility.

The end-cap ball bearing is suitable for a range of applications such as roller conveyors and, since no lubrication is required, unnecessary soiling and the 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.
