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.

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.

Abstract: A bearing with a wear surface sensor configured to wirelessly transmit information comprising a bearing wear surface containing a wear surface sensor wherein the wear surface sensor includes one or more connecting wires for transmitting a data signal from the wear surface sensor indicative of the state of wear of the bearing wear surface. The one or more connecting wires extend outside of the bearing wear surface and are connected to a radio frequency communicator for transmitting a data signal from the sensor indicative of the state of wear of the bearing wear surface. The radio frequency communicator and the sensor are fixed relative to one another such that the connecting wires are not flexed to failure during bearing use.

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.

Abstract: An angular contact bearing including an inner ring and an outer ring. Each ring includes a raceway. A plurality of balls are in rolling contact with the raceways. The bearing includes a retainer having a width being the distance between a first side and a second side of the retainer, an outer surface extending between the first side and the second side and an inner surface opposing the outer surface. The retainer also has a central portion having a first thickness T1, and tapered portions each having a second thickness T2. Each tapered portion 1) extends from one of said sides to said central portion up to 28% of the length of said retainer width, 2) tapers towards the inner surface of the retainer at an angle of 20° or less relative to said central portion, and 3) tapers away from the inner diameter surface of the outer ring.

Abstract: A load slot bearing assembly includes an inner bearing member and an outer bearing member. The inner bearing member includes a first circular end, a second circular end, and a spherical outer bearing surface between the first and the second circular ends. The outer bearing member includes a first end surface, a second end surface, and an inner spherical bearing surface between the first and the second end surfaces. The inner spherical bearing surface is shaped to allow the inner bearing member to fit within the outer bearing member. The outer bearing member also has a load slot, which includes a first and a second end faces, and a cylindrical surface extending from one end of the outer bearing member inwardly. The cylindrical surface connects the first and a second end faces. The load slot also includes an angulated surface connecting the cylindrical surface with a portion of the inner spherical bearing surface.

Abstract: A high-speed bearing vibrational analysis system for testing a bearing includes a bearing holding member to accommodate a shaft and the bearing. The bearing holding member is adapted to rotate the bearing at high-speeds. The shaft is inserted into an accommodation portion of the bearing holding member. A vibration sensor is in contact with the bearing to detect vibrations of the bearing, while it is rotated at high speeds, and to transmit data for analysis. A computer system is provided for executing a software program that receives and analyzes the data from the vibration sensor.

Abstract: A low vibration motion translation system for converting continuous rotary motion into reciprocating linear motion employs a counterweight or counterbalance mechanism moving in the opposing direction to the reciprocating linear driver or piston to reduce vibration. As the counterbalance is driven linearly in the opposing direction to the reciprocating piston, opposing forces are generated to counteract the unbalanced forces created by the translation, with a resultant reduction in vibration.
