* Clamp capacities are listed at 350 bar maximum operating pressure with a standard length link clamp lever installed. Total clamping force is divided equally between each side. Minimum operating pressure is 34.5 bar for double acting. The clamping force is adjustable by varying the hydraulic system pressure. Use of an extended length lever will result in a reduction of clamp force. (Actual force will vary slightly due to mechanical inefficiencies, and friction.) Concentric design allows reaching up through a bore to clamp a single part.
** Equal to +/- 10˚ with standard lever.
*** To ensure maximum service life and trouble-free operation, restrict fluid flow to the flow ratings when clamping. If you are unable to measure flow rates, these devices should be positioned in no less than 1/2 second. These recommendations apply when using the standard lever. When using the optional extended lever or your custom lever, please restrict the flow rates to position the lever in no less than 1 second.
Vektek's patented Pivot Equalizing System equally divides force between each side and allows height variations.
