Self-adjusting toggle clamps
Self-adjusting jaw height for rapid clamping
The power to be in position fast!
With the new self-adjusting toggle clamps from BESSEY, work pieces of differing heights can be clamped both quickly and securely. This makes them perfectly suited for use in small-scale production situations. However, it wouldn‘t be a BESSEY toggle lever clamp if our development team hadn‘t come up with another stand-out feature – true to our company motto “BESSEY. Simply better.” – which is the ability to automatically adjust to different work piece heights
while also maintaining constant clamping force. This makes time-consuming manual adjustment of the pressure screw a thing of the past. BESSEY toggle clamps have even more to offer when it comes to their flexibility; the clamping force can be optimized to the demands of the particular workpiece, simply by turning a set screw on the cantilevered joint. Furthermore, the hole pattern on the base plate has been designed to facilitate fast and secure clamping set-up. All this makes it an extremely – flexible clamping tool – give it a try!

Your benefits at a glance:
1 Automatic adjustment of the jaw height The BESSEY self adjusting toggle clamp automatically adjusts to the height of the particular work piece. The infinitely variable jaw height is up to 40 mm (1 O In.) for the horizontal toggle clamp and up to 16 mm (⅝ In.) for the push/pull clamp while the clamping force remains unchanged. This renders time-consuming manual adjustment of the pressure screw unnecessary.
2 Set screw on the cantilevered joint Using the set screw on the canti-levered joint, the clamping force can be adjusted to your particular require-ments, up to 2,500 N (550 lbs).
3 Hole pattern on the base plate The base plate, which is suitable for both metric and imperial, has been designed to facilitate fast and secure clamping set-up.
4 Ergonomic handle The plastic injection molded and ergo-nomically designed handle fits well in the hand and has a very good grip.

Machine table clamp
For clamping onto the machine table
Rapid, powerful and safe when clamping to equipment
At BESSEY you will also find a range of practical work table clamps – ideal clamps for assembly, drilling, rubbing, milling, grinding, honing, eroding, testing and much more. Original BESSEY BAS clamps are characterised above all by their incredibly compact design and high clamping pressure. The housings and clamping arms are made from tempered stainless steel and are therefore extremely heavy duty – even after many years of use and in the most restricted spaces. The work table clamps BS and the claw machine
clamp GRS can be tilted and are infinitely adjustable. The BS identifies a lever mechanism that facilitates quick clamping and releasing. When unobstructed access to the work area is a requirement or when clamping has to be done in confined spaces, the claw machine clamp GRS provides the necessary function thanks to an externally-positioned spindle. And, thanks to its swivelling pressure plate, the BSG work table clamp also provides the answer when clamping sloping parts, up to 35 degrees. As you can see, a comprehensive product range of products that leaves virtually no desire unanswered!

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 Time-saving automatic clamping and release system Only the BAS-U matic clamp is equipped with this function which automatically fastens and releases the work table clamp. During the clamping process, a hardened flat spring automatically presses on the underside of the screw head. Pressing on the release button on the back side releases it easily from the table.
5 Space saving and adjustable The compact design, both in height and surface requirements, distinguishes all of the models. Clamping height (up to 100 mm) 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.
