The RADIA series maintenance-free linear guides consist of a C-shaped aluminum profile and guide carriages equipped with rollers. There are four sizes of guide series—CEL, CL, CP, and CEP—depending on the load capacity. The carriages have either 3 or 5 rollers, with the rollers made of either steel or POM. The maximum length of the guide rails is 5,500 mm, and they can be custom-drilled according to customer specifications. Telescopic versions of the guides are also available.
