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.

HOLD DOWN
ACTION
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.

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. |

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.
|
 |
MODEL
801 NEW!
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.
