About Moment Loads

Multipiece Aluminum Carriage

Multipiece Zinc Carriage

One-Piece Aluminum Carriage

Guide Rail

With a wide base and low-profile design, these carriages and guide rails stabilize moment (twisting) and off-center loads better than standard carriages and rails. Use in areas where multiple carriages or rails won't fit. Sleeve bearings allow them to outperform ball bearings in wet, dirty, and high-vibration environments. Mount in any orientation without affecting load capacity.

Aluminum carriages conduct and dissipate the heat produced by friction, protecting your machinery. They are more corrosion resistant than zinc carriages.

Zinc carriages are mildly corrosion resistant.

One-piece carriages are less likely to become misaligned over time than multipiece carriages, which have four distinct bearing blocks.

Locking Extra-Wide Sleeve Bearing Carriages and Guide Rails

Zinc Carriage

Guide Rail

A handle on the side of the carriage locks the carriage in place. Carriages have a wide base for stabilizing moment (twisting) and off-center loads better than standard sleeve bearing carriages. Use them in areas where multiple carriages or rails won't fit. The sleeve bearings allow them to outperform ball bearings in wet, dirty, and high-vibration environments. Mount in any orientation without affecting load capacity.

Zinc carriages are mildly corrosion resistant.

Low-Profile Sleeve Bearing Carriages and Guide Rails

Style B Carriage

Guide Rail for Style B Carriage

For applications with low clearance, these carriages protrude less than 5 mm above their rails. Use them for light to moderate loads, as well as frequent starting and stopping applications where tight tolerances are not required. Sleeve bearings allow them to outperform ball bearings in wet, dirty, and high-vibration environments. Mount in any orientation without affecting load capacity.

Self-Aligning Low-Profile Sleeve Bearing Carriages and Guide Rails

Style B Carriage

Guide Rail for Style B Carriage

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.
