It has extremely high stiffness, high precision, and low friction, requiring much less space than other linear guidance systems.

When a positioning/positioning or positioning/non positioning bearing device with high load-bearing capacity is required within an unlimited displacement distance, a linear cyclic roller guide system can be used. These guiding systems include INA linear loop roller bearings with cylindrical rollers as rolling elements and HYDREL guides with up to four loop bearing raceways. The linear circulation drum guidance system is preloaded, with extremely high stiffness, high precision, and low friction; They allow for compact designs that meet specific application requirements. Suitable for high acceleration recirculation without involving rolling elements, its characteristic is smooth and quiet operation. Unlike ordinary guidance systems, the accuracy is actually not affected by lubrication films.
