Linear axes with lead screw drive



drylin linear axes with lead screw drive are designed for positioning tasks of all kinds. The linear adjustment takes place via trapezoidal lead screws of different sizes or via high helix lead screws, which can be set in motion either manually or electrically. The max. travel speed is up to 1.6m/min depending on thread and load. The length of the stroke is freely selectable for any linear drive system. A stroke of max. 1,500mm is possible for a plain-bearing mounted lead screw, and a stroke length of 1,000mm for a ball-bearing mounted lead screw.

Definition of a lead screw drive

The lead screw drive is one of the drive systems of the linear drives. The translational movement of the moving body is generated by a rotating lead screw and transmitted to the lead screw nut. So it is a rotary movement converted into a linear motion. Industrial examples include the lead screw drive for an automatic boot lid of a car, as well as lead screw drives required for opening and closing dome lights, conventional windows or roof windows for natural ventilation.

Lead screw drive: advantages and disadvantages

When to use it?

  • For format adjustments
  • In extreme environments
  • When a cost-effective, ready-to-fit solution is required
  • When corrosion resistance is required
  • When a quiet operation is required

When not to use it?

  • When high loads need to travel at highly dynamic forces
  • When positioning accuracy of < 0.1mm is required
  • When high running performance in continuous operation is required


Lead screw materials

igus relies on self-locking trapezoidal lead screws made of steel and stainless steel for all drylin linear units. Lead screws made of hard-coated aluminium are also available on request for special applications.
High helix lead screws made of stainless steel are optionally available and configurable for the series of linear modules with lead screw drives (SHT) and linear modules based on drylin W (SLW). These options allow much higher travel speeds and gradients, which eliminates self-locking.

Shaft materials

Shafts made of hard-anodised aluminium belong to the standard range and are the most frequently used version. The reason is a low coefficient of friction and wear and short delivery times. If the linear axes with lead screw drive (SHT) type is used, steel or stainless steel shafts are conceivable in addition to aluminium.

Bearing materials

Without the use of external lubricants and also maintenance-free? This applies to all bearing points of the drylin linear units for drive technology. The high-performance polymers are optionally available for applications with high temperatures up to +180°C (iglidur X). If FDA-compliant components are required, iglidur A180 bearing materials will help.

Motors for lead screw axes

As can already be seen from the example of the above-mentioned boot lid of the car, the electric lead screw drive is becoming increasingly important due to a variety of motorised adjustment options. In electronic drive technology, igus offers suitable linear axes based on lead screw drives that can be operated with hybrid stepper motors as well as DC motors (DC gear motors). The safety of the machines is ensured by integrated encoders and freely positionable proximity switches. The igus linear axes are completely ready for installation and connection. The clean and dirt-resistant operation is advantageous. Just visit our motors shop and benefit from our efficient and precise technology for your specific application.
