Ball Bearing Carriages and Guide Rails





Operating with less friction than sleeve and roller bearing carriages, ball bearing carriages provide accurate movement and positioning in high-speed, high-load applications. However, they don’t hold up to dusty and wet environments as well as sleeve bearing carriages. Mount in any orientation without affecting load capacity. End seals keep lubricant in and dirt out. Add optional guide rail bellows to protect the rails from contaminants as carriages move across them.
Standard carriages are narrower than flanged carriages, making them better for confined spaces.
Add a hand brake to lock carriages in position. To install, fasten the brake to the same mounting surface as your carriage.
Mounting hole plugs protect mounting fasteners from corrosion. Carriage and guide rail systems for 5 mm-12 mm wide rails include mounting hole plugs with the guide rails.
Note: Each carriage can only be used with its corresponding guide rail.

For made-to-order guide rails, please specify the length of the rail (in 1 mm increments). The mounting holes will be centered along the rail.

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. Ball bearings provide accurate movement and positioning at high speeds under heavy loads. Mount in any orientation without affecting load capacity. End seals keep lubricant in and dirt out. Add guide rail bellows to protect rails from contaminants as carriages move across them.

Horizontal-Mount 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. The ball bearings provide accurate movement and positioning at high speeds under heavy loads. End seals keep lubricant in and dirt out. Add guide rail bellows to protect rails from contaminants as carriages move across them.

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. An internal reservoir continuously supplies grease for maintenance-free operation, making them great for hard-to-reach places.

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. They also run quietly, since the bearings aren’t colliding. End seals keep dust from entering, and the cage traps lubricant around the bearings, reducing friction and heat buildup. Ball bearings provide accurate movement and positioning at high speeds under heavy loads. Mount in any orientation without affecting load capacity.

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. The ball bearings operate with less friction than sleeve and roller bearing carriages to provide accurate movement and positioning at high speeds under heavy loads. However, they’re worse than sleeve bearings in dusty and wet environments. A plastic cage separates the ball bearings to minimize noise, reduce heat buildup, and eliminate ball collisions. End seals keep lubricant in and dirt out.

Low-Profile Sleeve Bearing Carriages and Guide Rails



For applications with low clearance, these carriages protrude less than 5 mm above their rails. Use them for light to moderate loads, as well as frequent starting and stopping applications where tight tolerances are not required. Sleeve bearings allow them to outperform ball bearings in wet, dirty, and high-vibration environments. Mount in any orientation without affecting load capacity.

Self-Aligning Low-Profile Sleeve Bearing Carriages and Guide Rails


Compensate for rail misalignment in low-clearance applications with these carriages and guide rails. These carriages stick out less than 5 mm above their rails, giving them a low profile. They have a floating bearing that adjusts to correct misalignment between rails, so your carriages still move in tandem. Use them for light to moderate loads and applications with frequent starting and stopping where tight tolerances aren’t needed.
For a complete system, you’ll need a self-aligning carriage and rail on one side and a fixed-alignment carriage and rail on the other (all sold separately).
Carriages for axial rail misalignment compensate when the rails aren’t installed at the same exact height.
Carriages for parallel rail misalignment compensate when one rail is straight and the other is installed at a slight angle.
Carriages for axial/parallel rail misalignment compensate when the rails aren’t installed at the same exact height and also when one rail is straight while the other is installed at a slight angle.
Note: Each carriage can only be used with its corresponding guide rail. Load capacity is diminished when carriages are mounted upside down or on a vertical surface.
