Are there any normative references?

No, there is no standard reference for the guide shoes. However, the PFB guide shoes have been tested by TÜV with regard to their load capacities in terms of both axial and lateral thrust. We have calculated the load capacity in the catalogue on the basis of the values given in the TÜV certificate.
All bearing units and runner blocks manufactured by PFB have a minimum safety factor of 6, which means that the axial and transverse load-bearing capacity is calculated at 6 times the stated load-bearing capacity.
