CKR/CVR

Versatile and innovative curved linear guides with radial ball bearing rollers. The curvilinear guides are available in different versions, with constant or variable radius. Curvi line is ideal for applications such as curved machine housings, door systems in trains or boats, or customized packaging units.
The rail come in two widths, 16 mm and 23 mm. Both rails and sliders are zinc-plated as per ISO 2081. Strokes over 3000 mm are available. Straight and curved paths in one rail is possible.
Sliders with four rollers, arranged in pairs, maintain the preload over the whole length of the rail.
We customize for each application according to drawing.
