Workholding

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.
