Corrosion-Resistant Ball Screws and Nuts


	Ball Nuts, Externally Threaded Nut, Style A	Ball Nuts, Externally Threaded Nut, Style B	Ball Nuts Flange Nut Style C	Ball Nuts Flange Nut Style D

Suitable for use in harsh environments, these ball screws and nuts are made of stainless steel. Internal ball bearings provide smooth low-friction travel in applications that require high speeds, accurate positioning, and repeatable movement. Also known as single-start ball screws and nuts, they have a single thread that runs the length of the screw. They operate with more torque than fast-travel ball screws and nuts. To ensure compatibility, select components that have the same thread size. Ball nuts are furnished with a tube to keep ball bearings in place. Do not remove the tube until you are ready to install the nuts onto the screws.

Ball Screws—Right-Hand Threaded

Travel Distance per Turn—Travel distance per turn, also known as screw lead, is the distance a ball nut moves with one revolution of the ball screw.

Root Diameter—Root diameter indicates the diameter the ball screw will be after machining away the threads.

Fast-Travel Corrosion-Resistant Ball Screws and Nuts

Multiple thread channels (also known as thread starts) create faster linear travel than ball screws with a single thread start. Suitable for use in harsh environments, these ball screws and nuts are made of stainless steel. Internal ball bearings provide smooth low-friction travel in applications that require high speeds, accurate positioning, and repeatable movement. To ensure compatibility, select components that have the same thread size. Ball nuts are furnished with a tube to keep ball bearings in place.

Dry-Running Electric 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 electric slides work well for automated assemblies and other applications that require fine, repeatable motion control.

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

Low-Temperature Electric Slides

Slide

Controller

(Included)

Precisely position parts in conditions as cold as -90° F. These slides contain a grease that lubricates even in low temperatures. With an integrated stepper motor, they’re a complete motion control system for automated assemblies. A controller is included, so you can adjust the speed, timing, and positioning. These slides are often used in actions that require fine, repeatable movement, such as drilling, fastening, assembly, and measuring. The carriage extends the same distance every time within -0.02 to 0.02 mm, a margin thinner than a sheet of paper.

For the Manufacturer User Manual, click on a part number and select Product Detail.

Dynamic load capacity is the maximum load slides can move. If you increase the speed, the dynamic load capacity decreases. Use a load-speed chart to confirm which slides will work for your application. Click on a part number and select Product Detail to view the chart.

436 mm Overall Length—436 mm lg. slides come pre-programmed with no extra software required.

Travel Distance per Full Step—Travel distance per full step determines the control you have over the slide’s positioning. The smaller the measurement, the finer positioning control you have.

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

Cords—Use a USB cord (sold separately) and free downloadable software to program the controller for slides that are not 436 mm long.

Clean Room Electric Slides

Slide

Controller

(Included)

Prevent dust from circulating while precisely positioning parts for drilling, fastening, assembly, and measuring. These slides have a built-in vacuum port to remove fine particles that could damage electronics or contaminate batches in clean rooms. Because they have an integrated stepper motor with an included controller, you can adjust the speed, timing, and positioning. At -0.02 to 0.02 mm, these slides have a repeatability thinner than a single sheet of paper, so the carriage hits the same spot every time. Unlike air-powered actuators, they’ll hold their position even if power fails. They’re also more energy efficient.

For the Manufacturer User Manual, click on a part number and select Product Detail.

Maximum Speed—Maximum speed is how fast the slide will move under no-load conditions. If you increase the load, the slide speed will decrease.

Travel Distance per Full Step—Travel distance per full step determines the control you have over the slide’s positioning. The smaller the measurement, the finer positioning control you have.

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

Cords—Use a USB cord (sold separately) and free downloadable software to program the controller.

Tight-Clearance Self-Aligning Stainless Steel Swivel-Tip Set Screws

Our most corrosion-resistant swivel-tip set screws. Made of stainless steel, they won't rust, but they're not as strong as alloy steel. With a low-profile tip, these screws fit in compact assemblies, shallow mounting holes, and precision equipment where space is limited. The tip pivots to conform to your workpiece's surface without damaging it.

18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they don't hold up to the harsh chemicals that 316 stainless steel can.
