Abstract
Actuator stem and rod end bearings having locking mechanisms are described. An example apparatus for use with a control valve actuator includes a rod end bearing having a bearing retainer and a shaft portion extending from the bearing retainer, where the shaft portion defines a first face. An actuator stem has a first end to be operatively coupled to a diaphragm plate of the control valve actuator and a second end to be coupled to the rod end bearing, where the second end defines a second face. The first face engages the second face to provide a lock that prevents rotation of the actuator stem relative to the rod end bearing when the actuator stem is rotated in a first direction.
