Automation of o-ring assembly requires many parts to work as a whole. Typically a vibratory bowl will separate the o-rings, feed them down a track into a dead nest for the o-ring gripper to pick and place the seal on the parts.
Pneumatic double acting cylinders require a four way two position valve to operate them. Combining these actuators can yield an efficient robotic pick and place system for lean manufacturing. Our fast deliveries bring your inventory costs down and keep your production schedule up.
All models are designed to facilitate part ejection and/or part seating; ideal when an ejector is needed for part placement or when a seal is to be placed along a shaft.

Pneumatically operated gripping, spreading and placement of Seals or ‘O’-rings [with the assistance of automated ‘O’-Ring placement machines] via a dual piston mechanism, one being housed within the other yet independently functioning/operating.
Per an association of connecting rods and piston the spreading jaws operate in an in & out, or open and close motion, while the ejector jaws are piston operated [only] during the ejection/extension part of the cycle with a spring operated return/retraction.
All models are designed to facilitate part ejection and/or part seating; ideal when an ejector is needed for part placement or when a seal is to be placed along a shaft.
The further outward the spreading jaws are utilized during the stroke cycle, the greater the amount of force applied to the ‘expansion of the O’-Ring/Seal.
The action/angle of the connecting rods and relative internal mechanisms apply an ever increasing force along the spreading jaws as they move outward.
This feature should be taken into account during design stages of assembly machines.
Models: [3] sizes available
Note: AGP-8 & AGP-10 offer thru-hole design, allowing for installation of seals and rings along the lengths of shafts or columns.
O-Ring grippers can be tooled to accommodate all types of rings and seals, from very small to very large. It is up to the imagination of the engineer to utilize the motions provided by these designs to achieve a desired outcome.
AGI does not design nor produce ‘fingers’ or ‘jaws’ for end customer applications.
Sensing: Per all models, available for end-of-stroke on both spreading and ejection.
AGP-6-OR is 2.500” dia. x 2.700” tall.
Spreading jaws have 14-55 lbs. force [each] @80 psi *
Ejector jaws have 80 lbs. force [combined] @80 psi.
AGP-8-OR is 5.000” dia. x 5.000” tall.
Spreading jaws have 70-462 lbs. force [each] @80 psi.*
Ejector jaws have 320 lbs force [combined] @80 psi.
AGP-10-OR is 7.000” dia. x 7.000” tall.
Spreading jaws have 112-1230 lbs. force [each] @80 psi.*
Ejector jaws have 750 lbs. force [combined] @80 psi.
*Depending where in the cycle of stroke it is measured. The farther the spread or opening of jaws, the stronger the force. This exponential force {curved} applies to all AGP-OR Grippers. Also, keep in mind these are ‘no’-friction numbers. Every application will entertain a different coefficient of kinetic friction depending on finger design, {height & length}, and should be taken into consideration during design stages of assembly equipment.
