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

Lighter than solid shafts, hollow shafts reduce your total system weight and allow you to run various media such as electrical wiring, compressed air tubing, coolants, or lubricants through the center.

With 2" of each end softened, it's easier to machine a custom end for mounting. The rest of the shaft is case-hardened, which increases hardness and wear resistance on the surface of the shaft while allowing the center to remain soft for absorbing stresses caused by shifting loads.

Clip retaining rings into the grooves to separate and position collars, supports, and housings.

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.

Loosen the clamping screw to install, then tighten to secure. Made of lightweight, corrosion-resistant aluminum, these shaft supports hold linear shafts perpendicular to the mounting surface. Use with light to medium loads where shaft alignment is not critical.

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

These carriages and guide rails are steel.

Suitable for clean room use, these carriages and guide rails are made entirely of stainless steel.

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

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 handle on the side of the carriage locks the carriage in place.

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.

C-shaped guide rails grip the carriage around the outside to support linear motion along walls and other vertical surfaces.

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

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.

V-shaped rollers and rails allow these carriages to operate well in dirty environments because the debris won't get trapped on the rail.

High-temperature PTFE-thickened grease enables these carriages to operate in temperatures up to 500° F, higher than any other carriage that we offer.

Nylon rollers and aluminum rails make these good for light duty applications.

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.

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

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.

Slides have a row of ball bearings on each side of the rail.

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.

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 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.

Internal ball bearings provide smooth low-friction travel in applications that require high speeds, accurate positioning, and repeatable movement. Also known as single-start metric ball screws and nuts, these have a single thread that runs the length of the screw.

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

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

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.

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