Saint-Gobain Meldin® 8100 and 9000 Self-Lubricating Polyimide

Combines Self-lubricating Dry Lubricants with a Porous StructureOne major application is high temperature ball bearing cages in Gyroscopes. Gyroscopes must operate with very low friction ball bearings. Meldin® 8100 and 9000 ball bearing cages are used because of their unique ability to combine self-lubricating dry lubricants with a porous structure that can contain high temperature oils.These oils are vacuum impregnated into the material. These two important features ensure that these life critical applications will have a lengthy storage period (since typical external lubricants will dry out over time) and operate over a wide range of operating temperatures.
