• Improved wear-resistance, better sliding properties and increased fatigue strength over conventional bimetal bearings
• Polymer resin binder with anti-wear and solid lubricant additions to address intermittent lubrication situations
• Works well with either nodular cast iron or forged steel crankshafts, therefore accommodating cost efficient or high performance engine architecture

GLYCODUR® Dry Bearings

GLYCODUR® F

GLYCODUR F bearings have a copper-plated 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 top layer made up of the same material forms the running-in layer.

GLYCODUR F bearings combine, in an 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 excellent dimensional stability and thermal conductivity.

GLYCODUR® A

GLYCODUR A dry sliding bearings also have a copper-plated 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 dry sliding bearings are less affected by misalignments, including related edge loads.

GLYCODUR® AB

GLYCODUR AB sliding bearings contain a similar composition to GLYCODUR A sliding bearings, with the exception of a 0.35 mm top layer made of POM. This difference 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.

GLYCODUR® Mesh Material

GLYCODUR Mesh Material is used in applications such as bushings for automotive door hinges, bushings for seat belt preload devices, bushings for belt tensioners and bushings for seat recliners.

• Clearance-free installation due to high degree of flexibility
• Very small installation space
• Cost-effective

The design and materials used in the manufacture of bearings for internal combustion engines are specially matched to each specific application. We recognize that every bearing has its own individual function.

Bearings come in different forms depending on where they are to be installed. For radial loads, bearing shells and bushings are used, while for axial loads thrust washers or thrust collars are required. Federal-Mogul manufactures and supplies:
