Where to use Glycodur® A /AB
GLYCODUR A slide bearings have a copper-plated steel backing and a 0.2 to 0.4 mm thick, sintered-on layer of tin bronze. The key feature of these bearings is the coating polyoxymethylene (POM) layer with its relative thickness of 0.3 mm with lubrication recesses for lubricating grease.
GLYCODUR A slide bearings are therefore insensitive to misalignment and associated edge loading to a certain extent.
The GLYCODUR AB slide bearings correspond to GLYCODUR A slide bearings by design, however their POM coating layer is 0.35 mm thick. This allows subsequent machining of the slide surface by drilling or turning already fitted bushes - also by reaming in special cases. This allows to eliminate misalignments or obtain a reduced bearing clearance.
All applications working in the mixed friction area using grease and oil lubrication such as on slowly rotating transmissions or adjustment movements.
