  • Method of molding a resin coated bearing, method of manufacturing a resin coated bearing, and a resin coated bearing molded by the molding method
    Patent number: 7895748
    Abstract: Disclosed is a method of molding a resin coated bearing. When a molten resin is injected toward a substantially central portion of a disk space of forming dies from a sprue formed on an upper die, the molten resin is filled into a cavity through a film gate after the molten resin is led to the disk space from a pin gate, so that any weld is absent on a resin member, which covers an outer race, thus enabling uniformizing a coating member in resin strength and suppressing generation of crack on the coating member even at the time of high loading. Also, since the film gate formed on a whole peripheral edge of the disk space is formed from a lower die and an upper die, there is an advantage that after working suffices to take out a resin coated bearing from the both dies and to cut a runner in the disk space.
