Abstract
PURPOSE: In preparing sintered oil-containing bearing, metal powder is radially pressed to form rod-type body, which is then sintered. The sintered body is again radially pressed into circular form body, thereby to economically provide products of l/d=13 to 40.
CONSTITUTION: Metal powder 1 is packed into a mortar and radially pressed with upper and lower pestles to be formed into pressed powder body 5. The pressed body is sintered 6, which is pressed at the peripheral surface by the pestles 3, 4 to be formed into true circular body and impregnated with oil to provide the desired sintered oil-contained bearing. Such procedure eliminates the conventional machining of square sintered body to obtain circular one. As a result, the damage to oiled pores will not occur. The working cost is less expensive. And products having true circularity and straightness are easily obtained.
