The present invention is directed at products and methods related to the manufacture of a bearing with a bearing liner and the bearing liner on its own. The bearing liner within the bearing includes a fabric with a bonding side polymerized resin composition dispensed on one side and a sliding side polymerized resin composition disposed on a second side that contains dispersed lubricant. The liner preparation also offers the ability for the liner to conform to a selected bearing surface.

Bearing and bearing liner

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 bearing compositions and methods of making the same

Sensor for wear measurement, method of making, and method of operating same

Methods for making a bearing are disclosed, wherein the bearing includes a substratum and a self-lubricating surface coating composition. The self-lubricating surface coating composition further includes at least one cured thermosetting acrylate and at least one phenolic resin. Methods includes the step of disposing the self-lubricating surface coating composition onto the substratum.

Method for making a bearing having a self-lubricating surface coating

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.

Self-lubricating surface coating composition

A self-lubricating liner includes poly(p-phenylene-2, 6-benzobisoxazole), polytetrafluoroethylene, and a resin. The self-lubricating liner has superior strength and temperature resistance, abrasion resistance, thermal conductivity, and low moisture regain.
