  • Patent number: 11841048
    Abstract: 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.

  • Patent number: 10184520
    Abstract: 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.

  • Publication number: 20180011038
    Abstract: A wear sensor comprising: an insulating substrate having a top surface and a bottom surface; a conductive electrode formed on said top surface of said insulating substrate; an insulating wear lining material having a first side secured to said top surface of said insulating substrate and conductive electrode, an opposite second side that will be worn down by relative motion between the wear sensor and a moving component; one or more contact points where the electrical properties between the electrode and the moving component can be measured; and one or more perforations through the thickness of the substrate and electrode, through which an adhesive may flow, thereby increasing the peel strength between the wear sensor and race or between the wear sensor and the wear liner.

  • Patent number: 9314815
    Abstract: 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.
