Link Clamps and Levers
TuffLink™ 360° Double Acting Twin Lever Design Screw-In Cartridge Mount
Made possible by Vektek’s equalizing system!
Available in 3 sizes, 4.89kN, 7.56kN, and 11.57kN total clamping force at 350 bar (35Mpa). Significantly increased vertical clamping stroke over standard link clamp. Clamp through a hole onto the surface of your work piece. Clamp on two parts with one link clamp. Load equalizing mechanism allows
Cartridge mount body is manifold mount only. Cartridge mount body minimizes clamp footprint with easy to machine cavity. Levers must clamp on flat surface. Levers sold separately.
D-2
uniform clamping when work piece surfaces are within 1.5 millimeters.
U.S. Patent No. 8,678,362
Specifications
* Clamp capacities are listed at 350 bat 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.
