Double Acting TuffLink 360 Link Clamps
Link Clamps
- Available in 3 sizes, 4.36kN, 6.22kN, and 10.4kN total clamping force at 350 bar.
- Cartridge mount body is manifold mount only.
- Cartridge mount body minimizes clamp footprint with easy to machine cavity.
- Patented rotary lug feature delivers 360° of lever and/or body positioning.
- Maximum clamping force – minimal footprint.
- Levers sold separately.
*Clamp capacities are listed at 350 bar maximum operating pressure with a standard length link clamp lever installed. 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.)
** Equal to ±3° with standard lever.
*** To ensure 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, 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.
For proper sealing, the mating surface must be flat within 0.08 mm with a maximum surface roughness of 1.6 mµ Ra.
