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.

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.
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.
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.
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.

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.
This device was built to test welds thoroughly. Bending specimens with a force of 5,000N are possible with this machine. In addition to the standard drylin lead screw unit range, which implements the format adjustment of the bending die, linear guides of the drylin W series are also used. With them, the specified support distances are adjustable.
Jungheinrich AG, a manufacturer of industrial vehicles, developed a low-platform truck for a large-scale Scandinavian dairy, which collects trolleys that can be inserted into each other. The aim is to bring the trolleys to a washing facility. Instead of two usual forks for receiving pallets, just one fork is used here. It is controlled by a specially developed multifunction controller.
Fricke Abfülltechnik GmbH & Co. KG came across igus while searching for positioning options of the filling head for its filling plant. A ready-to-install linear module of the SHT series reliably performs this task. This impresses with its lubrication-free, compact design and is more cost-effective than alternative systems. The filling head can be operated by a hand wheel with little effort.
Bernhardt Maschinenbau oHG focuses on the design of folding and gluing machines. drylin components were perfect due to a low coefficient of friction and wear, maintenance-free feature and long service life. In the filling level device, a lead screw linear system of the SLW series is used, which contributes to weight savings.
While adjusting the format of bag sizes in forming, filling and sealing machines, it requires a system that does not use any lubricant due to the risk of contamination and operates completely maintenance-free over the entire machine running time. In addition to other plain bearing solutions from igus, a drylin SET easytube linear tube system is used.
