Linear Bearings

Linear Ball Bearings

Use ball bearings in debris-free environments and when speed is a necessity. They operate with less friction than sleeve bearings, so you can run them at higher speeds.

High-Load Linear Ball Bearings

Designed to handle heavy loads, these bearings have higher load capacities than comparable standard linear ball bearings.

High-Temperature Linear Ball Bearings

The choice for low-friction motion in high-temperature environments.

Linear and Rotary Ball Bearings

Engineered for simultaneous linear and rotary motion, these bearings are used with round end-supported shafts.

High-Load Linear Ball Bearings for Support Rail Shafts

Designed to handle heavy loads, these bearings have higher load capacities than comparable standard linear ball bearings for support rail shafts.

Linear Ball Bearings for Support Rail Shafts

Ball bearings create less friction than sleeve bearings, so they require less force to operate.

High-Temperature Linear Ball
Bearings for Support Rail Shafts

The choice for low-friction motion in high-temperature environments.

Linear Bearings for Spline Shafts

Grooved on the inside, these bearings rotate with your spline shaft as they move loads up and down its length.

Mounted Linear Bearings

Flange-Mounted Linear Ball Bearings

The flanged housing makes these bearings a good solution for vertical linear motion applications.

Corrosion-Resistant Flange-Mounted
Linear Ball Bearings

The shell, housing, and balls of these bearings are stainless steel for excellent corrosion resistance.

Mounted Linear Ball Bearings

Choose ball bearings for debris-free environments and when speed is a necessity. They operate with less friction than sleeve bearings, so you can run them at higher speeds.

High-Load Mounted Linear Ball Bearings

Designed to handle heavy loads, these bearings have the highest load capacities of any mounted linear ball bearings we offer.

Adjustable Mounted Linear Ball Bearings

Use the adjustment screw in the housing to tighten or loosen the snugness (also known as preload) of the bearing to your shaft.

Corrosion-Resistant Mounted Linear Ball Bearings

Outdoor as well as mild chemical environments are no problem for these bearings. They have stainless steel balls for corrosion resistance.

High-Load Mounted Linear Ball
Bearings for Support Rail Shafts

Designed to handle heavy loads, these bearings have higher load capacities than comparable standard mounted linear ball bearings for support rail shafts.

Corrosion-Resistant Mounted Linear
Ball Bearings for Support Rail Shafts

Outdoor as well as mild chemical environments are no problem for these bearings. They have stainless steel balls for corrosion resistance.

Mounted Linear Ball Bearings for Support Rail Shafts

Mount these bearings on a support rail shaft for applications requiring maximum rigidity.

Mounted Linear Bearings for Spline Shafts

Ready to mount on your linear motion spline shaft, these bearings come installed in a housing and have grooves that match up with the splines on your shaft.

Linear Bearing Housings

Flange-Mounted Linear Bearing Housings

Slide up to two linear ball or sleeve bearings into these housings and secure them with the included internal retaining rings.

Linear Bearing Housings

Slide up to two linear ball or sleeve bearings into these housings and secure them with the included internal retaining rings.

Ball Screws and Nuts

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.

Fast-Travel Ball Screws and Nuts

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

Self-Stopping Ball Screws and Nuts

Keep your ball screw spinning without the ball nut damaging your system. When the ball nut reaches the stop pin at either end of the ball screw, it disengages and begins to idle.

Corrosion-Resistant Ball Screws and Nuts

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.

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.

Metric 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.

Track Roller Carriages and Guide Rails

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 Track Roller
Carriages and Guide Rails

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

Light Duty Track Roller Carriages and Guide Rails

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

Light Duty Side-Mount Track
Roller Carriages and Guide Rails

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

Side-Mount Track Roller Carriages and Guide Rails

Mount along a wall or other vertical surface.

Corrosion-Resistant Side-Mount Track
Roller Carriages and Guide Rails

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

Self-Aligning Side-Mount Track
Roller Carriages and Guide Rails

Create a self-aligning carriage and guide rail system to compensate for mounting surfaces that aren't parallel.

Ball Bearing Carriages and Guide Rails

High-Cycle Low-Profile Ball
Bearing Carriages and Guide Rails

Run many cycles in tight spaces before replacing or re-greasing carriages.

Ball Bearing Carriages and Guide Rails

These carriages and guide rails are steel.

Horizontal-Mount Ball Bearing
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.

Maintenance-Free Ball Bearing
Carriages and Guide Rails

These carriages and guide rails are steel.

Miniature Ball Bearing Carriages and Guide Rails

These tiny carriages and guide rails are sized for electronic and other precision applications.

Corrosion-Resistant Maintenance-Free
Ball Bearing Carriages and Guide Rails

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

Side-Mount Ball Bearing Carriages and Guide Rails

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

Horizontal-Mount Quiet-Ride Ball
Bearing Carriages and Guide Rails

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.

Corrosion-Resistant Ball Bearing
Carriages and Guide Rails

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

Extra-Wide Ball Bearing Carriages and Guide Rails

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.

High-Cycle Ball Bearing 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.

Clean Room Ball Bearing Carriages and Guide Rails

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

High-Cycle Extra-Wide Ball
Bearing Carriages and Guide Rails

With a plastic cage that surrounds the ball bearings to prevent them from colliding, these extra-wide carriages run quietly for many cycles without needing maintenance. All of these carriages have a wide base and low-profile design to stabilize moment (twisting) and off-center loads better than other carriages.
