GN615.8 Spring Plungers with Ball, Friction Bearing and Slot
Spring plungers GN 615.8 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 therefore 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.
Housing - Steel, blackened
Ball - Steel, hardened
Spring - Stainless Steel AISI 631
Friction bearing - Plastic, temperature resistant up to 90 °C
