Firestone AirPicker / AirGripper

These end effectors offer the user a wide range of advantages over traditional pick and place work holding devices. Simply by varying the air pressure in the picker or gripper, the user can conform the end effector to the diameter that is being handled and the force being applied to the workpiece. This is especially critical in applications with sensitive, thin-walled, or fragile objects. The object being picked up does not have to have a circular configuration. Since it has an elastomer bladder construction, it will conform to any shape.


Each picker or gripper can work with a wide range of diameters and workpiece weights. Firestone offers a wide range of standard configurations and sizes of AirPickers™ and AirGrippers™ to meet most industrial applications. Special AirPickers™ and AirGrippers™ can be, and in many cases already have been, developed to meet specific needs of a particular customer.

Recent additions to the AirPicker™  and AirGripper™  product line have been made in response to customer needs. These include thin-walled rubber wear sleeves (replaceable wear component designed to reduce abrasion on AirPickers™ and extend life) and nose cones (plastic cones used to guide AirPickers™ into workpieces in applications where alignment in inconsistent.


Conform to Any Shape

The inflatable rubber construction of AirPicker™ and AirGripper™ end-effectors allows a multiple number of shapes to be handled with one model.

Multiple Sizes Handled with One Gripper

The large expansion of Firestone end-effectors allows for multiple part sizes to be handled with just one size model. The diameter of an AirPicker™ end-effector can grow as much as 1.86 times the deflated diameter, while an AirGripper™ end-effector can grip around an object that is only 40% of the deflated diameter.

Delicate Handling

By controlling the amount of pressure within the bladder, Firestone end-effectors can handle delicate objects with the soft touch of rubber and air. The holding force is distributed over a greater surface area than a mechanical gripper, resulting in a soft and secure touch even with heavy loads.

High Load Capacity

The wide contact area associated with an AirGripper™ and AirPicker™ end-effector results in a higher load capacity. A mechanical gripper only contacts the small area with its “fingers”. The gripper contact area results in a firmer grip and higher load carrying ability.

Non-marring Contact

The soft touch of the rubber and air allows for glass and plastic objects to be handled without marring their surface. This has been proven in applications handling freshly molded test tubes, glass bottles, and photosensitive copier drums.

Wide Size Range

Our standard AirPicker™ end-effector line can handle objects with an inside diameter as small as 0.33 inches (8.5 mm), and as large as 4.13 inches (105mm). Our standard AirGripper™ end-effector line can handle objects ranging from 0.2 to 1.8 inches (5 to 45 mm) in outside diameter.

No Lubrication Required

The absence of bearings or moving parts means that no lubrication is required for a long durable life.

Low Cost

Firestone AirPicker™ end-effectors typically cost less than comparable mechanical grippers.

Long Life in a Dusty Environment

The AirPicker™ and AirGripper™ end-effectors do not use seals or bearings, which results in a more durable gripper in dusty environments.
