Swiveling ball joint assembly for grinding head assembly

Abstract

A swiveling ball joint assembly set into a center of a driver plate to be used with a grinding head includes a rigid housing having a socket and a flange extending outwardly. An elongated shaft defines a rotational axis having a ball end enclosed within the socket and a coupling end to be connected with a spider arm. A bearing is concentrically aligned with the rotational axis and rotatably attached to the elongated shaft. A mounting hole to allow connection by fastener to a driver to translate rotational motion from the spider arm to the driver. A protective boot extends from the socket to a shelf to prevent foreign material from contaminating the socket.
