Quality Components
Internal components are made
from hardened bearing and tool
steels. External components are
made from corrosion resistant
materials for resistance to
de-ionized water or for use in
FDA and medical parts handling
applications
Stainless Steel Shields
Stationary and non-contacting shields eliminate
the possibility of particle generation

Jaw
l Dual double acting opposed pistons, connected to both a jaw and a synchronizing
bar by a drive pin, actuate in opposite directions.
l The synchronizing bars are connected to the equalizer which synchronizes the motion.
l The purge/scavenge port can be used to expel or retain contaminates using pressure or
vacuum respectively.
l Suitable for internal or external gripping.
l The synchronizing elements can be removed for non-synchronous operation.
