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.
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.

Anti-Reflective Ultra-Corrosion-Resistant Ball Bearing Carriages and Guide Rails




A black chrome plating diffuses light, preventing reflecting light from causing equipment to malfunction. They're great for precision positioning systems that use photosensors or cameras, which are sensitive to light. The finish also resists rust two times better than 440 stainless steel alone. They have ball bearings, so they operate with less friction than sleeve and roller bearing carriages for accurate movement in high-speed, high-load applications. However, they don’t hold up to dusty and wet environments as well as sleeve bearings. These carriages have a standard profile that’s narrower than flanged carriages, making them better for confined spaces.
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.

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.

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. The floating bearing in these carriages adjusts to correct misalignment between rails, so your carriages still move in tandem. A complete system includes a fixed-alignment carriage and rail on one side and a self-aligning carriage and rail on the other. All components are sold separately.
Carriages can be adjusted for a snug or loose fit on the rail (also known as preload). They have permanently lubricated rollers to save maintenance time and effort.
Fixed-alignment rails have a C-shaped profile that ensures the system travels in a straight line.
Self-aligning rails have a rectangular profile that allows the carriage to move freely from side to side to compensate for misalignment.

Roller Bearing Carriages and Guide Rails




With a larger contact area than ball bearing carriages, roller bearing carriages provide better positioning accuracy and support heavier loads. Mount in any orientation without affecting load capacity.
Standard carriages are narrower than flanged carriages, making them better for confined spaces.
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.

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.
