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. |
MODEL
802
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. |

DE-STA-CO'S newest power
hold-down clamp Model 8071 is ideal
for dirty environments such as spot
welding and MIG welding. Exerting
forces are similar to Model 807-U,
but applied air pressures can go much
higher. Model 8071 also features an
enclosed/protected cylinder rod and
lower and narrower mounting profile.

MODEL
846, 847-S, 847-U
The 847-S (solid bar) and
847-U have the patented bar guide
feature. This provides additional
side support to the hold-down
bar and allows a take-up adjustment
to compensate for misalignment or
wear. Other features are similar to
preceding models. The hold-down bar
opens 95o. Accommodates any 1/2-13
spindle assembly (not included). This
is the air-powered version of model
247. EDP#

MODEL
849
A cam mechanism in the linkage
of this unique clamp will accommodate
up to a 1/2" part size variation.
Once set to the nominal (or average)
part size, parts up to 1/4" larger
or 1/4" smaller can be clamped without
changing the setting. Bar opens 90o.
Clamp bar can be machined or altered
to suit the application. |
ALSO AVAILABLE
With Magnetic Ring
Model 849-MR

MODEL
858
The pneumatic version of model 568,
this heavy-duty model uses forged
alloy steel links and steel components
machined to close tolerances. Base
is a 1/2" thick steel plate. All pivot
points have hardened bushings fitted
with hardened steel pivot pins. The
1 " x 1-3/8" steel hold-down bar may
be cut, drilled and tapped or welded
to adapt to application. Bar opens
92o. |

MODELS
817, 827, 868
Many times it is desirable to use
a right angle model where space dictates.
Applications such as rotary indexing
tables and injection molding operations
are examples. All three models can
be mounted on the side of the fixture
and the models 817 and 827 can also
be top mounted. Model 817 is the pneumatic
version of model 317, and it accommodates
any 5/16-18 spindle assembly (not
included). Model 827 can accept any
3/8-16 spindle accessory (not included).

MODELS
8820-2, 8825-1
As the newest items in our line of
pneumatic power clamps, Models 8820-2
and 8825-1 offer exceptional durability
in a compact design. These clamps
have been designed for long life and
offer many benefits to the user. The
clamp linkage is shielded between
the body halves, and retractable cover
keeps debris from getting into the
clamps debris from getting into the
interior of the clamp. The units can
be equipped with a sensing package
to sense the open/closed position
of the clamp. Available only in the
90 arm style. Features:
-Compact design
-Lightweight-less than 1 lbs
-Retractable cover to enclose linkage
-90 arm swings open 120
-Arm pre-machined with mounting
holes
-Sensing option available |

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. |

DUTY POWER ROLLER CLAMPS |
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. |

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. |
|
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. |
