Slide and guide rails

NEW: Self-lubrication versions

As a useful addition to its extensive slide system portfolio, KNARR has standardized maintenance-free, self-lubricating slide rails. Embedded graphite inserts provide lubrication during operation. This creates a lubricating film between the slide and the guide rail, which makes additional greasing superfluous.

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 alternative 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.
