drylin®: linear guide systems from igus
Linear modules with lead screw
The lead screw drive converts the rotary motion of a rotating lead screw into a linear movement. These systems facilitate linear adjustments through trapezoidal lead screws, available in various sizes, or high helix lead screws, which can be set in motion manually or electrically.
Max. travel speed up to 1.6m/min, depending on thread and load.
Stroke length freely selectable for any linear drive system. A plain-bearing-mounted lead screw has a maximum stroke of 1,500mm, a ball-bearing-mounted one 1,000mm.
✓ Precise positioning
✓ High load capacity
✓ Compact design
✓ Low-friction movement

Lead screw materials
For all drylin linear units, self-locking trapezoidal lead screws made of steel and stainless steel are used. Hard-coated aluminium and high helix lead screws made of stainless steel are also available upon request.
From the standard range, shafts made of hard-anodised aluminium are most frequently used.
All bearings are maintenance-free, with no need for external lubricants. The high-performance polymers are optionally available for applications with temperatures up to +180℃. FDA-compliant components are also available.
