Abstract

PURPOSE: To integrally form the bearing of rotatable outer race and imer race under light load by beforehand setting the separately molded outer race to metal molds, injecting resin or the like and allowing the same to mold and shrink.
CONSTITUTION: A separately formed outer race 5 is set to a lower die 9 in which a core 11 is protruding. An upper die 10 is then mounted to the core 11 and lower die 9. When resin or the like is injected through the gate 12 of the lower die 10, the resin or the like molds and shrinks at the time of solidifying, thereby producing a suitable gap between the outer race 5 and inner race 6 and forming slide ways. At the time of molding, parting agent is coated on the parting face 7 on the inside diameter side of the outer race 5 to make the molding easy and hold an adequate gap. With this method, the slide way of the inner race 6 is formed in conformity with the slide way of the outer race 5 and therefore varying accuracies and the accuracy of inside diameter sizes of the product are eased. The split type plain bearing integrally formed by this method will not pull off owing to the engaging concave and convex of the slideways and revolves freely.
