TuffLink 360 Double Acting Twin Lever
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 uniform clamping when work piece surfaces are within 1.5 millimeters.
- Cartridge mount body is manifold mount only.
- Cartridge mount body minimizes clamp footprint with easy to machine cavity.
- Levers must clamp on a flat surface.
- Levers sold separately.
* Clamp capacities are listed at 350 bar (35 MPa) maximum operating pressure with a standard length link clamp lever installed. See the TuffLink Link Clamp Levers for the clamping force of various lever lengths and pressures. Minimum operating pressure is 52 bar (5.2 MPa) for single acting devices. The clamping force is adjustable by varying the hydraulic system pressure. (Actual force will vary slightly due to mechanical inefficiencies, friction and/or return springs.)
** Equal to +/-3° with standard lever.
*** To insure maximum service life and trouble-free operation, restrict fluid flow to the above flow ratings when clamping. If you are unable to measure flow rates, the devices should be positioned in no less than 1/2 second. These recommendations apply when using the standard lever. When using the optional long lever or your custom lever, please restrict the flow rates to position the lever in no less than 1 second.
**** In-port valves require the use of manifold mount ports.
For proper sealing, the mating surface must be flat within 0.0508 mm with a maximum 1.6 µm Ra surface finish.
