Your benefits at a glance:
1 Flexible throat depth
BESSEY TWV clamping elements for
welding tables not only have innitely
adjustable throat depth, but are also
available in three handle variants.
2 100, 120 or 140 mm throat depth
On BESSEY TW clamping elements,
you can choose among three handle
variants and three throat-depth
variants.
3 Heavy-duty, custom design
The TWM28 clamping element has a
heat-resistant special pressure plate
with sintered steel insert, which can
be pivoted up to 35°. On the TW28GRS
gripping arm variant the spindle is
located on the outside, which enables
– among other things – free access to
the work area.
4 Perfect for railings
Whether the workpiece is round, oval
or square, the TWVAD Vario table
clamping attachments are ideally
suited; this is because they can be
innitely adjusted to the workpiece
being welded, from 60° internal to 60°
external.
5 Applying the quick clamp
Thanks to the TWA-STC adapter
and the appropriate TWX extension,
BESSEY toggle clamps with a hori-
zontal base plate can also be rapidly
applied to welding tables.
6 Diagonal und horizontal clamping
The tilting adaptor TW28AV used
in conjunction with the extension
TW28X allows angled or horizontal
clamping in a range from -52 deg. to
+52 deg.
7 Existing work table clamps
Are you already using BESSEY work
table clamps and want to also use
them on your welding table? This is
made possible by simply screwing the
TW28HO attachment into the hole on
the bottom of the work table clamp.

Your benefits at a glance:
1 Flexible in application
The work table clamps BS, BSG and
the claw machine clamp GRS can be
tilted and are innitely adjustable.
2 Rapid in application
The BS identies a lever mechanism
that facilitates quick clamping and
releasing.
3 In the tightest space
When unobstructed access to the work
area is a requirement or when clamping
has to be done in conned spaces,
the claw machine clamp GRS provides
the necessary function thanks to an
externally-positioned spindle.
4 Special tilting pressure plate
The BSG work table clamp has a
heat-resistant pressure plate which
is replaceable and can be tilted up to
35° so it can even clamp on angled or
sloping surfaces. It has an extremely
long service-life due to the oil-soaked
sintered steel insert‘s excellent sliding
and emergency running properties.

Machine table clamps
Your benefits at a glance:
1 Housings and clamping arms made
from tempered stainless steel
BAS clamps are approx. 30 % smaller
than comparable tools made by com-
petitors and still provide the same high
clamping forces. At a perpendicular to
the jaw face, the self-locking worm
gear unit exerts up to 16,000 N.
2 Clamping arm variants
with polyamide seal
To provide for gentle clamping with
optimum weight distribution, the short
and long clamping arms of the BAS
models are equipped with a swivelling
aluminium pressure shoe. And when
clamping has to be done in corners,
BSP models equipped with a pointed
clamping arm are the perfect tools.
A special polyamide seal protects the
interior against dirt.
3 Open or closed fastening holes
Models with an open hole can be
clamped and unclamped more quickly.
In closed versions, the screw, nut and
clamp form a unit. All BAS clamps are
easily fastened and released – thanks
to the T bar wrench with an integrated
hexagon ball head.
4 Space saving and adjustable
The compact design, both in height
and surface requirements, distinguis-
hes all of the models. Clamping height
can be increased progressively in 80
mm steps with the BESSEY BASO base
unit. When using more than one base
unit, care must be taken to provide
precise workpiece contact surfaces.
With extra-high clamping pressure,
space saving design

That has made BESSEY Tool one of the largest suppliers of manu-
al clamping and cutting tools in the world. In order to guarantee
the best quality, rails and spindles for example are drawn directly
from BESSEY Precision Steel. Round and prole bar steels with
the tightest tolerances and highest quality surfaces are produced
