主权项

1. A method of manufacturing a bearing comprising:
forming a ceramic precursor from a ceramic based powder in a binding agent; compressing the ceramic precursor, using a first die and a second die, to form a green body of a blank of the bearing including a first surface and a second, opposite surface respectively including a first recess and a second recess, and leaving a thickness of material between the first recess and the second recess; sintering the green body to form the blank of the bearing with the thickness of material between the first recess and the second recess; and forming a through hole through the thickness of material in the blank to connect the first recess and the second recess so as to form the bearing, wherein a maximum section of each of the first and second recesses is comprised between 1.5 and 5 times a section of the hole.
