The ring type carriage is designed for use with track systems with unidirectional bends of a common radii and for use with double edge ring slides and segments. The unique geometry enables carriages on a track system to travel from straight to curve with negligible play in the transition zone. 

Carriages are available with twin or double row bearings, and with floating bearings. Carriages with twin bearings have the smoothest running quality and have some compliance to accommodate misalignment. Carriages with DR bearings have better load capacity and stiffness. Due to the rigidity of DR bearings, carriages with this option are supplied as Controlled Height as standard.
