Metric Ball Plungers
Ball Plunger
Bodies are steel with
a zinc plate finish

Locking Element
Ball Plunger drawing

Plungers may be ordered with or without the locking element. Plungers without element are the same price, but are considered "specials" and cannot be returned. We recommend using without the locking element for applications in aluminum.

To prevent possible spring damage, use of a Northwestern Wrench is recommended when installing from plunger end.

End pressures are given in kilograms. Full pressures are the force kilograms needed to move the nose the distance shown in "C" columns.

Available with or without locking element. To order without locking element, add a "P" to the end of the part number.

The nylon locking element holds the plunger body securely in place without the need for lock nuts or other devices. We recommend a 90° countersink 1/32" larger than the major diameter of the mating thread to prevent damaging the element.

All dimensions in millimeters
