Grippers

Page 6 Specifications subject to change without notice or incurring obligations. Long Stroke Models Jaw opening is increased with greater guide shaft travel through longer cylinder blocks High Force Models Jaw closing force is increased by Integral booster pistons. Note: Jaw opening force is not increased. Gripper Selection Guide Long Stroke, High Force Models incorporate both booster pistons and extended cylinder blocks Standard Stroke Models SPG 100 SPG 200 SPG 300 SPG 600 SPG 600HF SPG 300LSHF SPG 600LSHF SPG 300LS Model SPG 100 SPG 200 SPG 300 SPG 300LS SPG 300HF SPG 300LSHF SPG 600 SPG 600LS SPG 600HF SPG 600LSHF Closing 5.5 lbs 9.8 lbs 22 lbs 22 lbs 100 lbs 100 lbs 88 lbs 88 lbs 402 lbs 402 lbs Opening 5.5 lbs 9.8 lbs 22 lbs 22 lbs 22 lbs 22 lbs 88 lbs 88 lbs 88 lbs 88 lbs Stroke (Open) 0.25" 0.40" 0.54" 1.16" 0.54" 1.16" 1.38" 3.75" 1.38" 3.75" Grip Force Per Jaw at 100 psi Choice of Stroke & Grip Force Choice of Jaw Styles J1 – Aluminum J3* – Steel J2 – Aluminum J4* – Steel J1/J2 (shown), J2/J1, J3/J4*, or J4/J3* List first the jaw you want near end port *Note: Steel jaws are required on all high force models Spring Open Option "F" & Spring Close Option "G" can be used to maintain grip force with loss of air pressure (fail safe) or as single acting grippers (single supply line to port). Non-Synchronous Compliant Type – Option "N" This configuration is provided by simply removing the rocker arm that normally provides synchronization. Jaws will comply to the centerline established by the part to be gripped. The combination of equal piston forces and internal friction prevents jaw drift. Strain Relief – Option "R" Air tubing is held by slotted clamps attached to the gripper face. Not available on High Force Models or SPG600 Models. Ports Front & Rear – Option "B" Note: End ports plugged Not available on SPG100 Models, SPG600 Models, or Long Stroke Models. Choice of Sensors – See page 12 & 13 Proximity Switches, Front Face Mount Uses rectangular body proximity switches mounted in a T-slot bracket on the gripper face. Switches are actuated by a pin on one jaw. Very precise sensing. 5mm Prox. Switches, End Mount – Threaded body prox. switches are mounted in a bracket on the gripper end and actuated by cap screw(s). Available complete with switches or as brackets only. 10-20-10 “SPG”Series Parallel Grippers Non-Synchronous Fixed Refer- ence Type – Option "P" (J2 & J4 Jaw Styles Only) Jaws operate completely independently thru 2 sets of ports (2 air valves required). One jaw is fitted with an adjustable stop for fixed reference point, and operates at 50% more psi. Viton Seals – Option "V" Bumper Options "C","D" & "E" The SPG is the only gripper in its class to offer urethane bumper pads for quiet, high-speed cycling. Available on SPG200 and larger models for "open", "closed" or both positions. Can be "stacked" to limit stroke. Interface Blocks – Option "H" Blocks provide a convenient way to attach endtooling to J2 and J4 style jaws. (Application shown on page 4, Problem #3C.) Other Options – See page 14 & 15 Center Locating Dowel Pin – Option "A" Dowel pin option establishes gripper centerline and includes an outboard dowel slot for precise alignment. Escapement Device – Option "Q" (J2 & J4 Jaw Styles Only) Same as Option "P" except both jaws have adjustable stops and operate on equal pressure. (See page 5, special example #3.) (Model SPG300HF shown) (Model SPG200 shown) Electronic or Reed Switches, Front Face Mount Electronic sensors or magnetic reed switches are mounted in a dovetail slotted extrusion on the gripper face and actuated by a magnet on one jaw. Cost effective and compact. (Model SPG300LS shown) SPG 600LS
