  • Solid lubricant and solid-lubrication rolling bearing
    Patent number: 10760616
    Abstract: A solid lubricant 11 is formed by molding and firing powder that includes amorphous and self-sintering carbon material powder 12, graphite powder 13, and a binder 14. The solid lubricant has high material strength and hardness, and also excellent impact resistance and wear resistance.
    Type: Grant
    Filed: September 16, 2014
    Date of Patent: September 1, 2020
    Assignee: NTN CORPORATION
    Inventors: Hisanori Aiga, Hiroki Manabe, Takahiro Gotou, Yoshinori Ito, Fuminori Satoji
  • Solid-lubrication rolling bearing
    Patent number: 9631672
    Abstract: A separator 8 including a solid lubricant is disposed between adjacent rolling elements 7. Relative movement of the adjacent rolling elements 7 and the separator 8 in a direction of separating apart in a circumferential direction is restricted by restricting members 10, and the restricting members 10 are disposed at plural locations in the circumferential direction. A minute gap ? is provided between the adjacent restricting members 10, to allow relative movement therebetween. This can provide a solid-lubrication rolling bearing capable of stably preventing rotational locking and unintended disassembling of the bearing for a long period.
