Cup Retainers

Cup and Cone Retainers are engineered for use in angular contact bearing applications. The strength of the retainer, plus its ability to hold and separate balls, is obtained by National's unique method of manufacture and assembly of the ball in the retainer. In this method, the metal is "wrapped around" the ball to provide maximum ball retention with minimum friction between ball and cage.
Custom Cup and Cone RetainerFor years, the cup and cone retainer has been thought of as a "bicycle ball bearing," but realizing its possibilities, engineers have developed a host of new applications for it. For instance, opposing cup and cone retainers provide an economical combination radial and thrust bearing. The one-piece assembly permits automated assembly with machined, stamped, or plastic molded parts.
