Spring Plungers with moveable ceramic ball and slot, stainless steel A4
EH 22051.
Spring plungers can be used for locating or for applying pressure, as a detent or for ejection.
The running of the ball minimises wear on the counterpart, this also results in a positive locking behaviour depending on the counterpart.
Another advantage of the moveable ceramic ball is the electric insulation.
Characteristics of the ceramic ball:
- Highly impact-resistant
- Abrasion resistant
- Antimagnetic
- Electrically isolating
The stainless steel A4 version ensures maximum corrosion resistance.
