Internal threads allow you to mount these shafts onto threaded studs and fasteners, no shaft supports needed.

For your compliance and quality assurance needs, these shafts come with a material certificate with a traceable lot number.

Keep a material certificate on hand for compliance and quality assurance needs. Certificates include a traceable lot number and material test report. These hollow shafts reduce system weight and allow you to run various media such as electrical wiring, compressed air tubing, coolants, or lubricants through the center.

For a snug fit with a linear bearing in high-precision applications, these shafts are turned, ground, and polished to tight diameter and straightness tolerances.

Position shafts an inch or two off the ground to maintain bearing and part clearance. Support rails provide stability over the entire length of shaft, allowing virtually unlimited travel lengths and eliminating bending under moderate to heavy loads.

Replace worn shafts in two-piece support-rail shaft systems, or mate with a support rail to create your own. The tapped mounting holes match those on our Support Rails.

Slide the shaft in to install, then tighten to secure. For use with light to medium loads where shaft alignment is not critical, these shaft supports brace the end of a linear shaft along the ground or other flat surface.

Create a support that fits the exact dimensions of your shaft to brace it along a flat surface. Good for use with square- and hex-profile shafts, these aluminum supports also work with round shafts of any diameter up to 1". Use them for light-to-medium-load linear motion applications where shaft alignment is not critical.

A removable collar allows access to the shaft without unbolting the flange. For use with light to medium loads where shaft alignment is not critical, these supports allow you to hold linear shafts perpendicular to the mounting surface. Secure the shaft by tightening the clamping screw.

From one compact system, transmit linear or rotary motion or both at once (sometimes called spiral motion). Because of these different motions, these ball screw/splines and bearings create efficient, fluid movements in complex automated applications, such as pick-and-place robots.

Made of stainless steel, these carriages and guide rails are more corrosion resistant than steel carriages and guide rails.

Designed specifically for use on horizontal surfaces, the contact angle of the ball bearings on the rail allows these carriages to last longer than other carriages.

Made of stainless steel, these carriages and guide rails are more corrosion resistant than steel carriages and guide rails.

A plastic cage surrounds the ball bearings and keeps them from colliding, so these carriages run for many cycles without needing maintenance.

Adapt most 15 mm guide rails to fit on T-slotted assemblies.

Small enough to fit in a camera zoom lens and other precision motion applications, these carriages and guide rails have a black chrome-plated finish that diffuses light to prevent reflecting light from causing equipment to malfunction.

With a wide base and low-profile design, these carriages and guide rails stabilize moment (twisting) and off-center loads better than other carriages and rails. They're good for use in areas where multiple carriages or rails won't fit.

Mount to vertical surfaces for applications where tight tolerances aren't required.

A floating bearing in these self-aligning carriages adjusts to compensate for misalignment between rails, so your carriages still move in tandem.

Create a self-aligning system that can be locked in place with these carriages and guide rails.

With a wide base, these sleeve bearing carriages stabilize moment (twisting) and off-center loads better than standard carriages. Use in areas where multiple carriages or rails won't fit.

Mate with a T-slotted rail to add linear motion to your assembly.

For applications with low clearance, these carriages protrude less than 5 mm above their rails.

Threaded inserts secure the bearing to the carriage and prevent it from loosening due to frequent starts and stops.

The square profile prevents loads from twisting and rotating.

Build loops, circuits, and curved paths in assembly stations and other repetitive processes.

These track roller carriages and guide rails are stainless steel for use in wet, corrosive environments.

Use these carriages and guide rails for light loads where precise movement is not required.

Needle-roller bearings give these track roller carriages higher load capacities than other track roller carriages.

Nylon rollers provide low-friction movement for light loads and corrosive environments.

Combine with a T-slotted rail to add linear motion to your assembly.

A linear scale and micrometer-like hand wheel measure travel distance in increments of 0.001".

A micrometer handle ensures accurate, repeatable positioning along a single axis—good for positioning parts, such as measuring and inspecting equipment, that are part of a larger automated system.

A thumb screw locks the slide to prevent movement in systems where vibration is present.

Three micrometer handles ensure accurate, repeatable positioning along three axes—good for positioning parts, such as measuring and inspecting equipment, that are part of a larger automated system.

With a row of crossed-roller bearings on each side of the rail, these slides have over twice the load capacity of standard low-friction slides and are better for handling shock loads.

Create your own positioning table or telescoping slide. Sets include four rails, two roller bearing cages, and eight end stops.

Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start.

Also known as trapezoidal-thread lead screws and nuts.

Also known as single-start and self-locking lead screws and nuts, these have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won't unexpectedly move when the lead screw is at rest.

Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start.

Multiple thread channels (also known as thread starts) create faster linear travel than ball screws with a single thread start.

Also known as single-start ball screws and nuts, these have a single thread that runs the length of the screw. They operate with more torque than fast-travel ball screws and nuts.

Found in hand-powered clamps, vises, grates, doors, and work tables, lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects.

A set of ball bearings reduces friction and secures the end of a ball or lead screw.

A crisscross thread pattern allows you to drive the nut back and forth without changing the lead screw's direction of rotation. When the nut reaches one end of the lead screw, it changes direction and travels back to the other end.

Mount these two-piece collars anywhere on an Acme lead screw without removing components.

Install these nuts on a rotary shaft to create a linear positioning system without a lead screw. Instead of threads, a set of angled ball bearings drives the nut along a shaft as it spins.

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.
