Spring Plungers smooth, without collar, with moveable ball

EH 22081.

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 plastic ball is the electric insulation.

Assembly

The locating hole has to be adapted to each individual application case. We recommend an F8 size location hole for easy assembly and a H9 size when tight fit is required.
