Inspection and Measuring Fixturing

Use these components in coordinate measuring machine (CMM) applications to raise a workpiece and reliably position it on a fixture plate with 1/4"-20 holes. They are not for use in machining applications.

Hold-Down Clamps

Hold-Down Clamp

Hold-down clamps thread directly into a fixture plate, tower, or compatible component. Slide the clamp down its shaft and press into place against the workpiece for a light hold. They're also known as tension spring clamps.

High-Load Positioning Slides

Made with Frelon bearings, these slides have over four times the load capacity of standard positioning slides. They have a precision lead screw for use in a variety of manual-positioning applications for laboratory and production equipment as well as for positioning parts for drilling, fastening, assembly, and measuring.

Travel distance per turn, also known as screw lead, is the distance the carriage moves with one revolution of the handle.

Two-axis mounting plates (sold separately) let you mount two slides together for motion along two axes.

Note: Capacities listed are for horizontal mounting only.

Positioning Slides for Stepper Motors

Add your own stepper motor and controller to precisely move the ball screw and carriage smoothly at high speeds, like a head on an inkjet printer. With a repeatability of ± 0.01 mm—thinner than a strand of hair—the carriage hits the same spot every time. These positioning slides work well for automated assemblies and other applications that require fine, repeatable motion control.

The carriage rides along the inside of the rail, making these slides more compact than traditional carriages and guide rails. Made of steel with a U-shaped rail, these slides resist twisting forces that could affect their positioning. This also means they can be installed with only one end supported or with both ends overhanging. The same load rating applies no matter how the slides are oriented.

Two-axis mounting plates (sold separately) secure two slides together for motion along two axes.

Travel distance per turn, also known as screw lead, is how far the carriage moves with one rotation of the ball screw.

Dry-Running Positioning Slides for Stepper Motors

With PTFE sleeve bearings and a low-friction ball screw, these slides don’t require the mess and maintenance of lubrication but still give you precise positioning anywhere along the length of their stroke. Because they have sleeve bearings, they have fewer moving parts, so they perform better in dusty and wet environments than slides with ball bearings. They’re also better at handling impact and vibration.

All slides require a stepper motor, driver, and controller (not included) to operate. As part of this system, they move in precise increments, like the head on an inkjet printer. These positioning slides work well for automated assemblies and other applications that require fine, repeatable motion control.

Travel distance per turn, also known as screw lead, is how far the carriage moves with one rotation of the ball screw.

Clean Room Table Air Slides

Move optical equipment and other electronics sensitive to dust and fine particles from a range of mounting positions. These air slides have a port that connects to a vacuum or exhaust system to remove particles created by friction inside the slide before they contaminate your space. Compared to standard air slides, these slides have a platform that extends the mounting surface to the top of the slide. This design reduces the total space needed for a full stroke length. Two guide rods keep the head steady as it extends and retracts.

A magnetic piston inside these slides activates relays and controllers when used with a sensor (sold separately). When the piston moves past the sensor, the sensor activates. You can use multiple sensors—one for each action you want to trigger.

For flexibility with your setup, mount equipment on top or in front of these air slides. Mount on top to reduce the space you need to move a full stroke length. Often used with gripping equipment, they have a larger mounting area than air cylinders. They also have two guide rods that keep the head steady as it extends and retracts.
