Air-Powered Rotary Grippers
These grippers pick up a product and turn it 180° before releasing. Use them with gripping fingers to lift and move items in pick-and-place applications. They have two air ports: one to move the jaws open and another to move them closed. The jaws can grip items from the outside as well as the inside.
Finger blanks (sold separately) come ready to mount, so you can make custom fingers without starting from scratch. Just machine the blank’s gripping end to create fingers that will securely grip your specific parts.
When used in pairs, individual blanks have a symmetrical design that’s suitable for most applications.
Uncut pair blanks can be cut off center, making them good for applications where symmetrical fingers may hit nearby objects, such as when moving around machine spindles and parts trays during machine tending.
Aluminum blanks are lightweight and resist rusting in wet environments. They’re softer than steel blanks, making them easier to machine and less likely to scratch your parts.
Steel blanks are stronger and more durable than aluminum blanks, so they’re less likely to break if they hit a nearby object. You can harden them for even more strength and durability.
Warning: Never use to lift people or items over people.

Vertical-Lift with 90° Tilt Plate-Lifting Clamps
Clamps can take a metal plate that is stacked horizontally and tilt it up 90° so it can be lifted in a vertical position. After lifting, clamps can place the plate back down in the original position (plate can not be flipped over).
Automatic close clamps close under their own weight; as the load increases, so does the grip. Clamps with a lock stay closed to prevent accidental release.
Manual open with lock and remote release clamps have a pull chain so they can open remotely when they are not under load. They lock when open for easy loading.
Warning: Never use to lift people or items over people.

Nonmarring Vertical-Lift with 180° Flip Plate-Lifting Clamps
Pads on these clamps prevent the grip from biting into the load. They can take a metal plate of any hardness that is stacked horizontally, lift it vertically, and then place it down horizontally on its other side. Clamps close under their own weight; as the load increases, so does the grip. The lock keeps them closed to prevent accidental release. Clamps automatically open and lock when they are not under load so a new plate can be easily inserted. They have an eye that pivots to allow lifting angles up to 15° without reducing the capacity. The eye adjusts to accommodate unbalanced loads.
Warning: Never use to lift people or items over people.

Swivel-Tip Gripper Screws
The serrated tip swivels to grip uneven and angled surfaces and the threaded stud lets you make quick height adjustments.
Ultra-fine serrations are the most closely spaced for the lightest penetration of the workpiece.
Extra-fine serrations are closer together for less penetration and a lighter hold on the workpiece.
Fine serrations penetrate the workpiece for aggressive holding.
