GN 615.8 Spring Plunger Ball with Friction Bearing with Slot

GN 615.8 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.
