Linear frictionless bearings include metallic bearing 1 with working and return sectors 2,3, rolling bodies 4 in form of metallic wheels with fixing dividers 5 manufactured in form of separate parts of polymer material.
Butt ends 8 of guide 1 are connected with adapters 6 with ducts 7 for movement of separators 5 and rolling bodies 4. Adapters 6 in form of taps made from polymer material are equipped with scrapers 9 also made from polymer material.
Adapters 6 are provided with oil ducts 10.
To be fixed on the machine, linear frictionless bearing is equipped with four attaching holes 11.
