ABSTRACT:
An improved rotating head that utilizes a box assembly that stores at least one locking element that that allows for movement of the locking balls within the box assembly such that a liner inserted into the box assembly biases the locking elements to a locked position to couple the box assembly and the outer barrel. An integrated wear surface of the present invention seals the bearing elements to extend the life of the rotating head and reduce downtime caused by necessary maintenance of the rotating head.
