Lead screws and nuts

dryspin lead screw technology is based on the principle of lubrication-free and maintenance-free linear technology. The specifications and geometries of our lead screw technology, which are matched to the polymer nut and lead screw, guarantee efficiencies of up to 82% and a service life that is up to 30% longer than conventional lead screw drives.

Lead screw nuts are available from the full range for every technical requirement. The full range includes lead screw nuts from 4 lubricant-free iglidur® high-performance polymers, in trapezoidal and high helix threads, cylindrical design or as flange variants.
