Carriage

Guide Rail for Carriage with PTFE Bearing

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.

Compensate for rail misalignment in low-clearance applications with these carriages and guide rails. These carriages stick out less than 5 mm above their rails, giving them a low profile. They have a floating bearing that adjusts to correct misalignment between rails, so your carriages still move in tandem. Use them for light to moderate loads and applications with frequent starting and stopping where tight tolerances aren’t needed.

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.

Carriages for axial/parallel rail misalignment compensate when the rails aren’t installed at the same exact height and also when one rail is straight while 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.
