Page 16 Specifications subject to change without notice or incurring obligations. “GR” & “GS”Series Angular Grippers Operational Features • Grip force easily adjusted by varying input pressure. • External adjustment of final "Jaw Open" and "Jaw Close" positions can be made while the gripper is mounted, pressurized and operational. Disassembly is not required. • Gripper body is marked "0" at open adjustment screw and marked "1" at close adjustment screw • Hardened parts and locking threads provide "stay put" adjustment. • Operating pressure 15 to 150 psi • Air or hydraulic service 10-15-10 Selection Guide Gripper Model GR21 GR21 GR22 GS21 GS21 GS22 Grip Force On Part Outside Inside Outside or Inside Outside Inside Outside or Inside (1/2") .045 .063 .045 – – – -04 (3/4") .144 .171 .144 – – – Standard Round Body & Square Body Styles -06 (7/8") – – – .207 .243 .207 -10 (1 1/8") .396 .504 .396 .396 .504 .396 -20 (1 5/8") 1.386 1.629 1.386 1.188 1.395 1.188 -30 (2") 2.727 3.177 2.727 2.430 2.790 2.430 -50 (2 1/2") 5.022 5.517 5.022 – – – Gripper Size Code (Cylinder Bore Size) To Determine Grip Force Use the formula and chart data shown below Chart shows power factors for gripping the part from its outside – and from its inside. The result is theoretical static grip force and does not account for inertial loading, pressure fluctuations,external friction, etc. Gripper Power Factors Hardened Steel Pivot Bushing Hardened Jaw Pivot Pin Case Hardened Stainless Steel Clevis Hardened, Angled Nose Screw in a Locking Thread Insert Provides Adjustment of Final Jaw Position Internally Lubricated O'Ring Seals Round or Square Cylinder Body Duralon ® Piston Rod Bushing Hard Anodized Gripper Body Pressure (psi) x (Power Factor from Chart) = Force (Pounds) Grip Length (Inches –Grip Point to Jaw Pivot) Duralon ® is a registered trademark of Rexnord Corp.
