 Composition - Characteristics

Sliding bearing material

Composition GLYCODUR® A/AB

GLYCODUR® A

GLYCODUR A dry sliding bearings also 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. This surface layer is relatively thick, 0.3 mm, and features pockets for lubrication grease. GLYCODUR A sliding bearings are therefore to some extent unaffected by misalignments including related edge loads.

GLYCODUR® AB

GLYCODUR AB sliding bearings have a similar composition to GLYCODUR A sliding bearings, but they have a 0.4 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 eliminate possible misalignments or to achieve small operating clearance.
