General information
Features and applications
GN 614.8 ball spring plungers are used for the pressure and block function, obtained thanks to the presence of a technopolymer friction block bearing.
The ball is mounted in the friction bearing which, while allowing mobility, makes locking much more effective.
The technopolymer bearing also acts as an electrical insulator.
Suggested tolerance for plunger housing hole:
- F8: for normal mounting;
- H9: for push-fit assembly.
