This wheel guiding wheel with a diameter of 50 mm made of POM (polyoxymethylene) has a very low coefficient of friction, perfect for rolling on aluminum or steel rails.
The internal bearing 6300Z made of chrome steel has a bore of 10 mm. The rolling is smooth, and the quality of the bearing allows it to handle strong accelerations. We have over-injected the plastic material onto the bearing so that it is firmly glued and cannot become dislodged.
