GRIP FORCE CALCULATION EQUATIONS:
IMPERIAL:
Total Grip Force [Ib] = (Pressure [psi] x Gr) x Tooling Length Factor Jaw Surface
METRIC: 加
Total Grip Force [N] = (Pressure [bar] x GF) x Tooling Length Factor
Fl2—> 12
F = TOTAL GRIP FORCE
GRIP FORCE CALCULATION EXAMPLE:
Gripper: Series GRR Size 63 x 200 2. Determine Tooling Length Factor = 0.84 [0.84]
Common Parameters: (from Tooling Length Factor graph)
Operating Pressure = 87 psi [6 bar] . )
3. Total Grip Force Calculations:
Tooling Length = 10 in [254 mm]
1. Determine Grip Force Factor Gr = 8.09 [522]
