Ball buttons GN 249.1 are mainly used with spring plungers when low wear and exact positioning are needed.
To achieve optimal locking of the spring plungers, the maximum distance a between the ball button and the spring 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 spring plungers with high spring loads.
