Self-Aligning Side-Mount Track Roller Carriages and Guide Rails

Fixed-Alignment Carriage

Self-Aligning Carriage

Self-Aligning Rail

Fixed-Alignment Rail

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.

Support Rail

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.

0.516" wide guide rails require a support rail (sold separately) for carriage clearance. Order one per guide rail.

90° Angle Rail

Half Round Rail

Round Rail

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.
