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.
