Information

GN 614.8 Stainless Steel-Spring plungers are used for locking as well as for pressure and hold-off functions.

The ball is mounted in a plastic shell so as to be freely movable, which enables rolling and therefor generally optimizes the locking characteristics. Above all, this reduces wear on the counter piece.

A further characteristic of these plungers is that the plastic bearing acts as an electrical insulator.

For the mounting hole, tolerance d₁ F8 is recommended for joined ﬁtting and d₁ H9 for press ﬁtting.
