The clamping force varies according to the clamp arm length. The clamping force F can be calculated using the following formula. Clamping force calculation formula: F = F cyl x ( B ÷ C ) x E F = Clamping force (lb) F cyl = Cylinder force (lb) F cyl = P x A P = Operating Pressure (psi) A = Cylinder Area (sq in) (See table below) B, C = Clamp Lever Length (in) (See Table below) E = Output Efficiency (Approx. 0.9 for standard length and 1.5 for extended length lever) ILSP16604 REV A

Double Acting Pneumatic Link Clamp Lever Output Curves

Modifications to levers that result in clamp ratios below that of the standard lever are not in the safe operating zone for the corresponding link clamp and could result in premature failure.
