Clamps

The SPN zero-point clamping system features a repeatability of 0.005 mm due to its sophisticated design. Thanks to its very high clamping forces and consistent use of tempered stainless steel, the system provides a high-precision, torsion-resistant base that also stabilises parts that have a tendency to vibrate. Zimmer’s zero-point clamping system is able to absorb maximum forces with maximum repeatability.

When it comes to flawlessly clamping and positioning workpieces, the flexible, adjustable and enclosed 82L-3E Series Power Clamps are the perfect choice for users. Specifically, the 82L-3E’s opening angle can be quickly adjusted with just one tool, which helps guarantee maximum flexibility of use.

The pneumatic clamps of the GN 860 series now have hardened, ground bearing bushings and tempered bearing pins for significantly reduced wear. No meaningful alterations were observed in testing for over 250,000 cycles. Structural reinforcement of the sheet steel housing reduces wear-inducing vibrations during operation, which makes a difference even under lower loads. And, finally, the new one-way restrictor in the cylinder enables smoother travel to extend the lifespan of the piston.

The user-friendly new models allow for fast handling and enable their users to build up applications more efficiently with little interference contour. The 503-MLBR and 533-LBR clamps are fully interchangeable with models having the same specifications, other models are available upon request.

The front-mount option is available for inclusion on a total of four manual clamps that can be used with both vertical and horizontal handle action. The two vertical operating models – 2002-UF and 2007-UF – provide enlarged space for manual operations and increased safety. The horizontal versions – models 225-UF and 235-UF – have a flat design that creates space for larger hand clearance, which improves operational safety.

Receiving the most extensive quality enhancements is the Model 802-U Manual Clamp. The updates include an upgraded air cylinder that ensures the clamp’s exerting force is less than the maximum holding capacity when operated at normal pressure, which extends service life; new composite bearings on the trunnion mount and cylinder pivot point that eliminate metal-to-metal contact while requiring no lubrication; and a redesigned clevis bolt, along with increased rivet and pre-stop diameters that increase longevity.

The economical, easy to use WPS Mini features manual Zero Point clamping that attaches directly to the workpiece, provides maximum holding force of 25 kN and highest repeatability of <0.005 mm. Single quick actuation provides rapid open and closing of the module with only a 270° rotation.
