ENGINEERING DATA: SERIES <strong>GRR</strong> GRIPPERSGUARDIAN GRIPPERGRIP FORCETotal gripping force relative to tooling length is shown below atthe stated actuating pressure. Grip force per jaw equals the total gripforce divided by two. The graphs also indicate the maximum toolinglength for each gripper size.F/2PARTJawSurfaceToolingLengthF/2F = TOTAL GRIP FORCETOTAL GRIP FORCE lb [N]900[4003]800[3559]700[3114]600[2669]500[2224]400[1779]300[1334]150 mm Travel100 psi [7 bar]CLOSEOPEN87 psi [6 bar]60 psi [4 bar]0 2 4 6 8 10 12 14 16 18 20[50] [100] [150] [200] [250] [300] [350] [400] [450] [500]TOTAL GRIP FORCE lb [N]900[4003]800[3559]700[3114]600[2669]500[2224]400[1779]300[1334]250 mm TravelCLOSEOPEN100 psi [7 bar]87 psi [6 bar]60 psi [4 bar]0 2 4 6 8 10 12 14 16 18 20[50] [100] [150] [200] [250] [300] [350] [400] [450] [500]TOOLING LENGTH in [mm]TOOLING LENGTH in [mm]200 mm TravelCLOSEOPEN350 mm TravelCLOSEOPENTOTAL GRIP FORCE lb [N]900[4003]800[3559]700[3114]600[2669]500[2224]400[1779]300[1334]100 psi [7 bar]87 psi [6 bar]60 psi [4 bar]0 2 4 6 8 10 12 14 16 18 20[50] [100] [150] [200] [250] [300] [350] [400] [450] [500]TOTAL GRIP FORCE lb [N]900[4003]800100 psi [7 bar][3559]87 psi [6 bar]700[3114]600[2669]500[2224]60 psi [4 bar]400[1779]300[1334]0 2 4 6 8 10 12 14 16 18 20[50] [100] [150] [200] [250] [300] [350] [400] [450] [500]TOOLING LENGTH in [mm]TOOLING LENGTH in [mm]GRIP FORCE CALCULATION EQUATIONS:IMPERIAL:TOTAL GRIP FORCE [lb] = (Pressure [psi] x GF ) x Tooling Length FactorMETRIC:TOTAL GRIP FORCE [N] = (Pressure [bar] x GF) x Tooling Length FactorF/2PARTF = TOTAL GRIP FORCEJawSurfaceToolingLengthF/2GRIP FORCE CALCULATION EXAMPLE:Gripper: Series <strong>GRR</strong> Size 63 x 200Common Parameters:Operating Pressure = 87 psi [6 bar]Tooling Length = 10 in [254 mm]1.
