摘要:
A self lubricated bearing contains a first member, a second member configured to slide against the first member, and a lubricating liner disposed in a sliding contact area between the first member and the second member. The lubricating liner contains at least one structural polymer and at least one lubricant with viscosity less than 5100 centistokes. A method is also provided for making the bearings, which includes adding the at least one lubricant with viscosity less than about 5100 centistokes to one or more components of the lubricating liner during the process of making the liner or bearing. The self lubricated bearing compositions of the invention have surprisingly long service lives versus prior art self lubricated bearings.

Self-lubricated bearings contain a substratum and a self-lubricating surface coating composition disposed thereon, wherein the self-lubricating surface coating composition further contains at least one cured thermosetting acrylate and at least one phenolic resin. The phenolic resin preferably contains a mixture of phenolic resin and polyvinyl formal resin. A self-lubricating surface coating composition is also provided, as well as several methods of making the bearings. The self-lubricated bearings of the present invention have surprisingly long service lives.

This invention relates to phenolic resin compositions containing less than 5 percent by weight of wholly inorganic expansible clay particles well dispersed therein, methods for making the same, and articles incorporating the same. The wholly inorganic clay particles are added to a phenolic resin liquid, where the clay form as added can range between a powder and a dilute aqueous dispersion. The resulting phenolic resin and clay compositions have improved physical properties and increased adhesion to other materials.
