Mz Mx Fa Mx RECOMMENDATIONS Design tooling so that the grip point is as close to the gripper surfaces as possible. The grip force factor (Gf) values given in the table on page 7 are for zero tooling length. As the grip point is moved away from the jaw surface, the applied moment causes jaw friction to increase, resulting in reduced effective grip force. Use the tooling length factor chart on the following page to calculate the effective grip force for a specific grip point. The maximum load that grippers can handle will vary based on: size of the part being picked up, shape of the part, texture of the part, speed at which the part is transferred, working pressure, shape of the fingers, etc. My My (800) 24-85 www.phdinc.com/grv www.phdinc.com/gra GRAV0

Dowel pin holes in the flange are clearance to allow dowel pins to install in the body for accurate mounting. See chart for recoended dowel pin lengths. The GR9 option is sealed between the body and the flange to allow use of the L-UB99 manifold option. The GR9 flange is also available in kit form. See Flange Mounting Kit chart.
