Linear guides of the drylin® T and W series, and the drylin® SD lead screw drives and linear carriages travel completely lubrication-free. This eliminates the risk of contaminating the housing, the filament, and the print result. In addition, the maintenance-free operation increases reliability. Commissioning after changing or servicing the extruder head or the nozzle size is quick and easy due to the drylin® N low-profile guide system.Apart from the lightweight due to the use of plastic and aluminium with a corrosion-free coating, the guides in the drylin® series impress with their principle of "gliding instead of rolling" and their quiet and precise running.
