GLYCODUR® A/AB

marginal maintenance

Where to use

GLYCODUR® A dry sliding bearings have a copper-plated steel base and a 0.2 to 0.4 mm sintered tin bronze layer. The major characteristic of thèse bearings is the POM top layer on the sintered bronze. This surface layer has a thickness of 0.3 mm and features pockets for lubricant. GLYCODUR® A bearings are insensitiveto misalignment and subséquent edge load. 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 final machining of the sliding surface on installed bushings by boring or turning, or in exceptional cases by rubbing, in order to eliminate possible misalignments, or to achieve small operating clearance.

Référence applications

With oil or grease lubrication such as slowly rotating gears or aligning movements.
