Linear guides
This company says it has improved and expanded its DryLin(R)linear guide system. Additions include the N17, which is a smaller version of the original, with a height of 6 mm and a width of 17 mm, with an all-polymer carriage corrosion resistance. Also added to the line is the wide-carriage for N80 model, which is said to eliminate the need for force placement analysis.
