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.
Flanged carriages have threaded mounting holes on the flanges rather than the carriage body, so you can fasten loads from both the top and bottom. When fastening from the bottom, use the mounting hole as a through-hole.
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.
Flanged carriages have threaded mounting holes on the flanges rather than the carriage body, so you can fasten loads from both the top and bottom. When fastening from the bottom, use the mounting hole as a through-hole.

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.
Flanged carriages have through-holes for access when fastening loads.
Add a hand brake to lock carriages in position. To install, fasten the brake to the same mounting surface as your carriage.

Maintenance-Free Ball Bearing Carriages and Guide Rails






With an internal reservoir that continuously supplies grease, these carriages and guide rails are good for use in hard-to-reach places. Ball bearings provide accurate movement and positioning at high speeds under heavy loads. Mount in any orientation without affecting load capacity.

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.

Sleeve Bearing Carriages and Guide Rails



With fewer moving parts and no need for lubrication, sleeve bearing carriages perform better in dusty and wet environments than ball and roller bearing carriages. They're also better at handling impact and vibration.
Carriages with PTFE bearing operate with less friction than carriages with a polyethylene bearing.
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.

Self-Aligning Sleeve Bearing Carriages and Guide Rails


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