Our iglidur materials for spherical insert bearings and spherical balls
Our igubal spherical balls and spherical insert bearings consist of various tribologically optimised iglidur materials that offer specific properties for a wide range of applications. All materials share the common advantages of wear optimisation, dust and dirt repellence as well as freedom from lubrication and maintenance thanks to integrated solid lubricants.
