SELF-SANITISATION AGAINST BACTERIA AND FUNGI
with friction block bearing, steel or stainless steel
Friction block bearing
Technopolymer.
Spring
AISI 631 stainless steel.
Standard executions
Black-oxide steel threaded body, hexagon socket head:
- GN 615.9-K: hardened steel ball, normal end-force spring.
- GN 615.9-KS: hardened steel ball, spring with heavy end-force.
Black-oxide AISI 303 stainless steel threaded body, hexagon socket head.
- GN 615.9-KN: AISI 420C hardened stainless steel ball, normal end-force spring.
- GN 615.9-KSN: AISI 420C hardened stainless steel ball, spring with heavy end-force.
Max. working temperature
90°C.
Features and applications
GN 615.9 ball spring plungers are the result of a further development of GN 615.8 for special applications, which require adjustment or positioning by means of a hexagon socket screw. They 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.
