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.

Thrust retainers hold and separate balls or needles in a thrust bearing to meet both the load and speed requirement of an application. Retainers can be used alone in an application or as part of a complete thrust bearing. National Bearings manufactures custom thrust retainers and has a large inventory of tooling to produce: Plastic Ball RetainerStamped Thrust RetainersPlastic Ball RetainersPlastic Needle Retainers
