About Moment Loads

Carriage

Guide Rail

A handle on the side of the carriage locks the carriage in place. With fewer moving parts and no need for lubrication, sleeve bearing carriages perform better in dusty and wet environments than ball and roller bearing carriages. They're also better at handling impact and vibration.

Note: Load capacity is diminished when carriages are mounted upside down or on a vertical surface.

Locking Extra-Wide Sleeve Bearing Carriages and Guide Rails

Aluminum Carriage

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.

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.

Replacement Locking Handle

A handle on the side of the carriage locks the carriage in place. Made with needle-roller bearings, these track roller carriages have higher load capacities than other track roller carriages. Carriages can be adjusted for a snug or loose fit on the rail. Rollers are permanently lubricated to save maintenance time and effort.
