SERIES 8000, 8100, 8200, 8300
Quick, Clean & Economical

Ideal for installations where hydraulic power is not suitable, these pneumatic power clamps from De-Sta-Co have all the same quick-acting advantages and can produce up to 160 lbs. clamping force from shop line air pressure (see chart). These double acting clamps are red anodized aluminum with either a threaded body that permits three mounting options, or a block-style mounting body.

Intended for quick clamping in secondary manufacturing operations on metallic or non-metallic products, these clamps offer a combination of features that makes them uniquely adaptable to such applications.


A pneumatic (or hydraulic) cylinder provides the activating force. The rugged construction provides repetitive production operations but at a cost low enough for short run jobs. These clamps also have the desirable safety feature of being mechanically locked (when fully closed) so that even a total loss of pressure will not cause them to cycle.
All 800 Series clamps are self-contained. They simply need to be mounted and attached to air or hydraulic lines.

Special High Temperature Seals (H/T Option)
These optional seals withstand temperatures to 400o continuous service.
Special Magnetic Ring (MR) Cylinder Option
If there is a need to sense the open or closed position of the cylinder, we can provide our cylinders with magnetic rings. Then, by adding a tie-rod mounted reed switch, you can sense the position of the cylinder.

The 802 provides 200 lbs. holding capacity in a package less than 7" long. The double acting power cylinder has built-in speed control (restriction) and needs only to be hooked up to a controlled air or hydraulic power source. Hold down bar opens 95o to facilitate easy part loading and unloading. Includes 1/4-20 neoprene spindle assembly (202208). Air powered version of model 202.

SERIES 840, 860, 890, 1000
Designed for high production applications, these toggle action pneumatic clamps offer exceptional clamping forces and holding capacities - far greater than other clamps of similar size. And unlike most pneumatic toggle clamps, they do not require greater pressure to open than to close.
Of special importance in the design of the Series 840 is the oval cylinder. Because of the extremely narrow profile of these clamps, they can be used in cramped quarters or can be ganged closer together in multiple installations.
The even numbered models in these series feature a 180o clamping arm which travels to an over-center locked position parallel (180o) to the clamp centerline. The corresponding odd numbered models have a 90o arm. The angular locked position of both versions is precisely controlled by the hardened steel insert. Clamp arms can be machined, drilled, cut off, or welded to suit the application requirements.
Many other versions of these clamps are available with special arms, proximity switch sensors, cushioned cylinders, and other features designed for automated clamping. Please contact the factory for information on the complete, specialized automation clamp line.


SERIES 870, 871
Power Arm Clamps
These models use a roller and cam principle and provide the following benefits:
- Able to clamp work of inconsistent thickness and still maintain a locked condition.
- Modular units 2-1/8" square can stack together for minimum distance between clamping points.
- Four-way mounting surface for full mounting flexibility.
- Built-in pre-stop eliminates need to bottom out cylinder. Gives extra travel to automatically compensate for wear. Also permits arm to be machined accurately relative to mounting surface.
- Clamp arms can be altered by welding, drilling or machining
to suit the application.


MODELS 800, 1200 NEW!
Low Profile Pneumatic Retractor Clamps
Even the smallest shop can now have rapid power clamping. The De-Sta-Co Low Profile Pneumatic Retractor Clamp operates on ordinary shop line air (properly filtered and lubricated). And the clamp arm completely retracts from the work area, for ease in part loading and unloading. The resulting increase in productivity can reduce your labor costs, too.
- Compact size and low profile for mounting in restricted areas.
- Uniform clamping force throughout full stroke.
- Variable clamping force allowed by regulating input pressure.
- Requires no auxiliary power source.
- Operates in any position or mounting angle.
- Clamping capacities to 1,200 pounds (at 250 psig).
- Both models available with extended arm, as Models 800E and 1200E.

Here's how it works:
1) Clamp arm retracts fully for loading and unloading ease.
2) Clamp arm moves straight forward and...
3)... pivots down to hold workpiece firmly in position.

This clamp is the newest in our of pneumatic retracting clamps. The unit is completely enclosed, making it useful in heavy machining applications. Its low and narrow profile allows it to be fit into tight/confined areas. The clamping arm action extends out horizontally, and then clamps down.  The double-acting cylinder has built in restriction to help control the speed of the cylinder.
