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.

Carriages with polyethylene bearing have high impact strength and are more abrasion resistant than carriages with a PTFE bearing.

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.
