Additional information

Body

AISI 303 stainless steel.
Features and applications

GN 817 indexing plungers offer the following advantages:<BR>- two retracting strokes (l1) per plunger Ø;<BR>- identical small dimensions l for type B and C;<BR>- retracting mechanism (type C) is shrouded in part;<BR>- defined thread length by an undercut at the end of the thread.<BR>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.<BR>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.
