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.

Features & Benefits
Supported T-Slot jaws help prevent jaw breakage while offering superior load/bearing performance.
Spreading and ejector jaws operate independently, allowing for exact timing of ring installation.
True parallel jaw motion, compact design, and adjustable stroke allow for easy tooling.

O-Ring Gripper Italiano
O-Ring Gripper Espanol
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.

Authorities in the field of ergonomics agree that repeated stress on certain joints and tendons is likely to cause ailments such as tendonitis, arthritis and carpel tunnel syndrome. Companies, as a result, suffer soaring medical costs and production losses. AGI President, Millo Bertini, stated:
“One great advantage of implementing O-Ring Installation Assembly Tools is that workers place less stress on their hands.” A direct result is that repeated stress injuries are reduced… something both workers and their employers benefit from.”
When manufacturing workers sustain injuries, there are implications to productivity and scheduling. Manufacturing outfits that embrace new technologies are finding themselves ahead of the curve as a result of decreased injuries among their staff.
AGI has recently made significant investments in their manufacturing plant, making it possible for them to deliver products to customers with a short lead time, and at low cost. Implementation of new robotics devices now faster than ever, and with today’s price points, the benefits of automation are available for small and mid-sized manufacturing plants.
AGI’s O-Ring-Assembly Tools are available in three sizes to accommodate placement applications ranging from 3 inch and up. Both the AGP-6-OR (which has six jaws) and the AGP-8-OR (which has eight) are designed to facilitate part ejection and part seating and are ideal for applications where an ejector is needed after part placement. They are both equally functional when a seal needs to be placed down a long shaft. The AGP-10 can handle any size ring with the assistance of specifically designed spreading fingers.
As a result of independent piston technology and double-acting spreading jaws, O-Rings that are stretched by these pneumatic grippers suffer considerably less deformation than they would if installed through traditional assembly methods. And there is no risk of over-expansion, as the opening stoke can be precision-adjusted.
