A process for the manufacturing of self-lubricating elements such as bearings, plates, bushings and the like with composites obtained by impregnating special synthetic fabrics with thermosetting resins, catalyst and nano graphite and/or molybdenum disulfide nano and/or nano PTFE and/or nanoboron nitride, each of these, or other nanometric lubricants, added according to the tribological applications and requirements of the product.

A sliding mechanism 1 includes a first sliding member 10 and a partner second sliding member 20 configured to slide relative to the first sliding member 10. The first sliding member 10 includes a matrix phase 11 and a hard phase 13 that is harder than the matrix phase 11, in which the hard phase 13 is embedded in the matrix phase 11 in a dispersed state. The second sliding member 20 includes a base 21 and a surface-treatment layer 23 that is formed on the sliding surface 20 of the base 21 and is harder than the matrix phase 11.

An actuator of a variable compression ratio mechanism for an internal combustion engine includes an arm link 13 configured to change a posture of the variable compression ratio mechanism for the internal combustion engine by swinging, a second control shaft 11 fixed to the arm link 13, and a housing 20 including a first bearing hole 301a supporting the second control shaft 11. The housing 20 includes a lubricant oil supply oil passage 202 opened to a pressure-receiving range over which a contact pressure is received at the first bearing hole 301a from the second control shaft 11 during an expansion stroke of the internal combustion engine.

A bearing device supports a shaft of a gas turbine engine. A first support disk is mounted to the bearing housing element. First tilting pads are tiltably arranged one after another along a circumferential direction at the first support disk. A second support disk is mounted to the bearing housing element spaced apart from the first support disk along an axial direction. Second tilting pads are tiltably arranged one after another along the circumferential direction at the second support disk. A first number of the first tilting pads is greater than the half of a second number of the second tilting pads but smaller than the second number of the second tilting pads.

A fluid bearing apparatus includes a stationary member and a rotating member. A bearing surface of the stationary member and a bearing surface of the rotating member are arranged opposite to each other with a minute gap therebetween. The minute gap has a fluid arranged therein. At least one of the bearing surfaces includes a first dynamic pressure groove array. The first dynamic pressure groove array includes a plurality of first dynamic pressure grooves arranged unevenly at irregular intervals in a circumferential direction.

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.
