GN615.8 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.
