Linear bearing made of FDA-compliant polymer

Compliant and reliable

First linear bearing made of FDA-compliant polymer

Our new linear plain bearings made of iglidur polymer are designed for use in filling/food/pharmaceutical technology. Cost-effectively injection moulded from the FDA-compliant material iglidur® A180, the bearings are extremely tough and resistant. Also very easy to clean and the secure press fit in the bearing housing leaves no gap or space to the housing wall.
