ABSTRACT:
A ball catch for releasably retaining a grooved shaft comprises a hollow bushing, a guide part mounted in the bushing for axial movement, rolling elements disposed between opposing surfaces of the bushing and guide part to facilitate movement of the guide part, and a hemispherical socket seated on the front end of the guide part. A locking ball is disposed in the socket and is seated on a plurality of small bearing balls to facilitate rotation of the locking ball. A spring biases the guide part forwardly. The socket and guide part are formed of deep-drawn sheet parts and are fixedly joined together. The guide part is configured to impart radially outward elastic biasing forces to the rolling elements to eliminate any radial play of those elements between the bushing and guide part.
