Guide rails for slides
As a useful extension to the broad range of slide applications, KNARR standardizes slide bars in different designs.
Lateral guide rails, gliding and retaining rails are made of cold work steel 1.2842, centred and T-shaped guide rails are made of material 1.2379. Both materials guarantee typical properties such as high wear resistance and good dimensional stability. The rails are hardened to ~ 58 HRC. A standard DLC coating provides optimal gliding and dry running properties. Radial lubrication grooves facilitate additional lubrication. All standard rails allow individual shortening to the required finished size. The choice between the two different hole distances of 25 and 50 mm is a convenient option in this context. The slide rails are manufactured with a grinding allowance for the exact alignment of slide and guide rail.
Centred guide rails are particularly suitable for complex and large slide constructions and guarantee precise slide guidance despite thermal expansion. Another interesting option are space-saving T-bars that do not require any lateral retaining rails.
