(Example) When using LHA0480-A
Supply Hydraulic Pressure 5.0MPa, Lever Length L=50mm,
Clamping force is about 3.1kN.
L : Lever Length (mm)
Notes：
1. Tables and graphs shown are the relationships between the clamping force (kN) and supply hydraulic pressure (MPa).
2. Cylinder output (when L=0) cannot be calculated with the formula of clamping force.
3. There may be no lever swing action with large inertia depending on supply hydraulic pressure or lever mounting position.
4. The clamping force is shown with lever in the locked position.
5. The clamping force varies depending on the lever length. Set the supply hydraulic pressure suitable to the lever length.
6. Using in the non-usable range may damage the clamp and lead to fluid leakage.
7. The tables and graphs are only for reference. The exact results should be calculated based on the clamping force calculation formula.
※1. F ： Clamping Force (kN), P ： Supply Hydraulic Pressure (MPa), L ： Lever Length (mm).
※ Clamping force curve is the same as that of standard model LHA.
