I've attached a model.
locating surfaces are tightly controlled for flatness. Bearing motion is great until torque is applied. We speculate we are distorting the bearing cage in some way - perhaps as the threads elongate...
Long time "looker", first time "poster".
I am currently having trouble with the motion on a minature linear slide (less than 1" long) used to control the motion of cantilevered arm of small mass. The motion of the slide is affected when we torque the arm down to the threaded holes on the top of...
