SELF LUBRICATED WITH EXTRAORDINARY DRY-RUNNING PROPERTIES

Carbon and graphite materials are used in a wide range of applications where traditional lubricating methods are not appropriate. Carbon and Graphite solutions from Mersen are self lubricated, in other words, external lubricants are simply not necessary.

CONTINUOUS PERFORMANCE

Bearings, sealing and guiding solutions made of carbon and graphite materials by Mersen give the designer increased options to support the continuous performance of the process.

HIGH FATIGUE STRENGTH:

due to its high resistance to corrosion, the carbon-graphite material lasts longer with limited impact from its environmental factors.

UNIFORM STRENGTH:

performance remains exceptional even at high temperature

DIMENSIONAL STABILITY UNDER WIDE TEMPERATURE VARIATIONS:

Carbon-graphite materials have a low CTE

MERSEN PROVIDES EXPERTISE AND ENGINEERED SOLUTIONS THROUGH A COMPLETE RANGE OF CARBON AND GRAPHITE OFFERING.

Temperatures exceeding 100°C to 150°C prohibit the use of standard oils and grease. The thermal stability and self-lubricating features of carbon allow its use as a bearing material in this temperature range.

At high temperatures

WHERE AND WHEN CARBONS AND GRAPHITES SHOULD BE USED

In corrosive fluids or atmospheres

Carbons and graphites are chemically inert and corrosion resistant. Wherever ordinary lubricants are not recom-mended, carbons and graphites perform well, either dry in a corrosive atmosphere or immersed in corrosive liquids.

To avoid contamination by lubricants

Carbons and graphites are critical in applications where the presence of oil or grease, even in vapour form, is prohibited. Examples can be found in the food, pharma-ceutical and textile industries.

When lubrication is difficult or expensive

Carbons and graphites are efficient dry self-lubricants.

Where moving parts are inaccessible

Without carbons and graphites, the maintenance of certain types of equipment becomes virtually impossible due to difficult access to moving parts.

When weight saving is required

The density of carbon is about 1,5 to 2,5. Much lower than metals.

SOLUTIONS:GUIDING AND FRICTION: bearings, thrust bearings, rotors, vanes, bushing

DYNAMIC SEALING: sealings, sealing rings, segmental rings

AEROSPACE: main shaft seals, Flex tubing seals, APU (Auxillary Power Unit) seals

ROTATING EQUIPMENT:

Rotating shaft and pistons in pumps, compressors, turbines, fan, blowers, belt chain conveyors, dryers, mixers, vanes, blades…
