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. They’re good for use in areas where multiple carriages or rails won't fit. End seals keep dust out, 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.
Standard carriages are narrower than flanged carriages, making them better for confined spaces.
Flanged have four 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.
Mounting hole plugs protect mounting fasteners from corrosion.
For technical drawings and 3-D models, click on a part number.

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.
