GN 249.1 Ball Buttons Steel, for Ball Plungers / Spring Plungers


Product description


GN 249.1 ball buttons are mainly used with ball plungers / spring plungers when low wear and exact positioning are needed.

To achieve optimal locking of the ball plungers, the maximum distance a between the ball button and the ball plunger should not be exceeded. The maximum distance a is calculated from the difference between the compression w of the selected plunger and the indentation depth s of the ball in the recess.

These ball buttons are especially recommended for use with ball plungers or spring plungers with high spring loads.
