Part Options


These pneumatic OD clamps allow for holding on the circumference of irregularly shaped workpieces. The four part aluminum jaws can be machined to custom fit the part. When air is applied, the center of the jaw is pulled downward, causing the jaw sections to tilt toward the center to clamp the workpiece. These clamps allow for part repeatability of +/- 0.03 mm and jaw locating repeatability of ±0.02 mm. The clamping stroke of each jaw is .15 mm. The body is made from 1045 steel with an electroless nickel plated finish. The jaw is made from A7075 aluminum, anodized blue. The part numbers include the clamps, jaws, locking ring, diamond pin and socket head cap screw. Additional sets of jaws can be purchased separately.
