Abstract

PURPOSE:To obtain the fine bearing with little generation of flashes and without requiring secondary processing for synthetic resin rings by making specific the metal mold for forming the synthetic resin rings projected slightly from the outer-peripheral surface of an outside wheel in the peripheral groove of the surface. CONSTITUTION:The outside wheel 11 of the bearing is inserted into the set hole 23 of the metal mold 2 and is positioned so that the peripheral grooves 12 and 13 of the outside wheel 11 are opposed to the grooves 24 and 25 of the set hole 23 and to gates 29 and 30. The diameter D23 of the set holes 23 is set to be slightly larger than the outside diameter D11 of the outside wheel 11. When melted resin is injected under high pressure from an injection nozzle N, it is injected and filled up in the peripheral grooves 12 and 13 of the outside wheel 11 and in a circular space between the peripheral surface of opposed set hole 23 and the grooves 24 and 25, then flexture is caused in the outside wheel 11 by injection pressure, the dimensions of separation the outer-peripheral surface of the outside wheel 11 to the bottom surfaces of the grooves 14 and 15 or the peripheral surface of the set hole are nearly uniformalized througout the whole periphery, and the height of projection of the rings 14 and 15 is also uniformalized. After filling-up of resin is completed, the outside wheel 11 is extruded in the axial direction of the hole 23 and removed therefrom and is assembled as the bearing.
