Bearings are preloaded for maximum
support and zero side play
Hard Coat Anodize
The body has hard-coat anodize
60 RC with PTFE impregnation
Purge/Scavenge Port
Purge/Scavenge port for extreme
environments from dirty and gritty to
clean-room Class 10 or better
Adjustable Preload Screw
Adjustable preload screw allows for adjustment
of preload on roller bearings
Contaminants
Units are lubricated with a
C-52
Clean-Room
clean-room
grade grease
Quality Components
External components are made from corrosion
resistant materials for resistance to de-ionized
water or for use in FDA and medical parts
handling applications
One Piece Body
One piece lightweight
aluminum body
Slip Fit Dowel Pin Holes
Located in body and jaws
Stainless Steel Cover
Stationary and non-contacting
cover eliminates the possibility
of particle generation
Roller Bearings
Patented Dual-“V” roller
bearings provide low friction
rolling motion and maximum
rigidity for fingers

Jaw
l A double acting piston is connected by a shaft to a double sided pin wedge.
l The pin wedge slides in a hole located in each of the jaws converting vertical
motion of the wedge into horizontal synchronous motion of the jaws.
l This gripper is suitable for internal or external gripping.
Unit has top manifold ports.
G
Fingers attach to jaws with screws and
locate with dowel pins or by keying.
