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. 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 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.
Mounting hole plugs protect mounting fasteners from corrosion.

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.

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.
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.

Locking Sleeve Bearing Carriages and Guide Rails for Curves






A handle locks these carriages in place on curved paths, loops, and circuits in assembly stations and other repetitive processes. Because these carriages and rails have a wide base, they stabilize twisting and off-center loads better than standard carriages and rails. They’re useful in areas that won’t fit multiple rails or carriages. The carriages have sleeve bearings that swivel, so they move around curves without jamming. Their sleeve bearings also work better than ball bearings in wet, dirty, and high-vibration environments. Mount them in any orientation.

Sleeve Bearing Carriages and Guide Rails for Curves






Build loops, circuits, and curved paths in assembly stations and other repetitive processes using these carriages and guide rails. They have a wide base, which means they stabilize twisting and off-center loads better than standard carriages and rails. They're useful in areas where multiple carriages and rails won’t fit. The carriages have sleeve bearings that swivel, so they move around curves without jamming. Their sleeve bearings also perform better in dirty, wet, and high-vibration environments than carriages with ball bearings. You can mount them in any orientation.

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. Wipers sweep away dust and contaminants and distribute lubricant along the rail. Carriages can be adjusted for a snug or loose fit on the rail (also known as preload). Mount in any orientation without affecting load capacity.

Track Roller Carriages and Guide Rails for Curves





Create a low-maintenance system with loops and curved paths in assembly stations and other repetitive processes. The track rollers that support these carriages keep contaminants out in dusty environments and prevent debris from getting trapped on the rail. You can adjust the carriages for a snug or loose fit on the rail (also known as preload).
Note: Each carriage can only be used with its corresponding guide rail.
