Body :
AISI 303 stainless steel.

Features and applications :
GN 817 indexing plungers offer the following advantages:
– two retracting strokes (l1) per plunger Ø;
– identical small dimensions l for type B and C;
– retracting mechanism (type C) is shrouded in part;
– defined thread length by an undercut at the end of the thread.
Version C with keyed knob is used in all the applications where the plunger must not protrude continually. In that case the knob is retracted and afterwards turned by 90°. A notch is provided for the key to prevent the plunger from turning by error or vibration.
Stainless steel, thanks to its high resistance to corrosion, allows the application of these indexing plungers on machines and equipment in those sectors where laws or particular hygienic, climatic and environmental factors make it mandatory to use corrosion resistant materials.

Knurled keyed knob :
High impact strength special technopolymer, black colour, matte finish (standardversion), red RAL 3000 RT. Resistant to solvents, oils, greases and other chemical agents.

Knurled knob :
High impact strength polyamide based (PA) technopolymer, black colour, matte finish (type B, BK). Resistant to solvents, oils, greases and other chemical agents.

Locking nut :
AISI 304 stainless steel (for type BK, CK, GK).

Other standard versions available :
Threaded drive rod for combination with knobs on customer’s request or to link the rod to an operating mechanism of the machine.
– Type G: without locking nut.
– Type GK: with locking nut.

Plunger :
AISI 303 ground nickel-plated stainless steel. Suggested matching hole in H8 tolerance.

Standard versions available :
– Type B: with knob, without locking nut.
– Type BK: with knob and locking nut, ISO 8675.
– Type C: with knob, without locking nut.
– Type CK: with knob and locking nut, ISO 8675.
