Linear roller guidance systems consist of a guide rail, a standard carriage plate and rollers. The rails are made of anodized, extruded aluminium (available in various sections) on which the round sliding bars in chromium-plated hardened steel are fixed through bevelling.
Thanks to the rollers being on an eccentric pin, it is possible to achieve perfect coupling with the bars and determine the desired preload. The rollers have greased for life 2RS protectors and can be with an ogival or a “V” profile with a 120° gap; the latter allow the impurities present in some work environments to be discharged better.
