dryspin®: linear guide systems from igus

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.

High efficiency at all speeds: iglidur® J	– High speed – Low wear – Best coefficient of friction
For temperatures up to +150°C: iglidur® J350	– For high temperatures – Good coefficient of friction with medium loads
For medium to high speeds: iglidur® R	– High wear resistance for low loads – Low moisture absorption – Vibration-dampening
FDA-compliant for the food and pharmaceutical industry: iglidur® A180	– FDA-compliant – For contact with food
Best running partner for hard anodised aluminium: iglidur® J200	– Low coefficient of friction and wear – Long service life
