GLYCODUR® dry sliding bearings are available as catalog commodity in two standard versions, GLYCODUR® F and GLYCODUR® A. Both versions have different sliding layers (see below) according to ISO 3547 type P1 and P2.
GLYCODUR® F sliding bearings have a steel base, to which a 0.2 to 0.4 mm porous tin bronze layer is sintered. The pores of this layer are filled during a rolling process with polytetrafluoroethylene (PTFE) and other friction and wear reducing additives. A 5 to 30 μm top layer made of the same material forms the running-in layer.
GLYCODUR® F sliding bearings combine in optimal manner the mechanical properties of the sintered bronze with the sliding and lubrication properties of a PTFE mixture. The structure of this composite material results in good dimensional stability and good thermal conductivity.

GLYCODUR® A dry sliding bearings have a steel base and a 0.2 to 0.4 mm sintered tin bronze layer. The principal characteristic of these bearings is the polyoxymethylene (POM) top layer, which is solidly joined to the sintered bronze. The surface layer, which is 0.3 mm thick features pockets for lubrication grease. GLYCODUR® A sliding bearings are therefore to some extent unaffected by misalignments including related edge loads.
GLYCODUR® AB sliding bearings have a similar composition to GLYCODUR® A sliding bearings, but they have a 0.35 mm top layer made of POM. This allows the final machining of the sliding surface on installed bushings by boring or turning, or in exceptional cases by reaming in order to adjust possible misalignments or to achieve small operating clearance.
