drylin® SLW linear unit with lead screw drive

Low-profile, tough, & torsional rigidity

Extremely torsionally rigid aluminium double-shaft profiles and a large number of linear carriage versions based on the drylin W linear system characterise the drylin SLW linear unit with lead screw drive. In addition to the low-profile linear rails, high, very tough linear rails are also available for the SLW linear modules. The SLW linear unit with lead screw drive is particularly suitable for manual format adjustment as well as for a motorised option for electrical adjustment.

Your benefits at a glance:

  • Variable carriage widths and lengths
  • Low-profile linear rails or robust high profiles
  • Corrosion-resistant option made of stainless steel available

drylin SLW linear units in use

Test the benefits of drylin drive technology

igus SLW linear units with lead screw drive are based on the drylin W linear modular system as well as on maintenance-free and self-lubricating dry-tech high-performance polymers. The lubrication is incorporated into the bearing material, rendering the linear axes and linear module suitable for dry-operating conditions, i.e. they are maintenance-free for their entire service life. Ready-to-install linear units are available in 2-4 days. See for yourself, ask for a free sample from us.
