General information
Features and applications

GN 249.1 ball bushings are used together with ball or bolt spring plungers whenever a contact surface with high resistance to wear is required.

For an optimum plunger detention, the max distance “a”, obtained from the difference between the spring travel "w" of the chosen plunger and the ball depth “s” inside the ball bushing cavity, must not be exceeded.

In particular, they are recommended for use with plungers with high spring loads and plungers with reinforced spring.
