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 drylin® 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.

Advantages of lead screw axes

When a cost-effective, ready-to-install solution is desired, lead screw axes are often the first choice. You can see here what other advantages the linear drive has over other systems with the aid of a lead screw:
 
precise

Precise positioning

By directly converting the rotating motion from the lead screw to linear motion, very accurate and repeatable positioning is achieved, which is critical in tight tolerance and high precision applications.
Compact

Compact design

Lead screw axes are also available in particularly small versions. Their compact design makes them perfect for all applications where only a small amount of installation space is available. Also discover our complete miniature series.

Heavy duty

High load capacity

Lead screw drives in linear modules are able to carry and move very high loads. In contrast to flexible toothed belts, for example, lead screw axes can ensure efficient force transmission thanks to their low rigidity.

Movement

Low-friction movement

Linear modules with lead screw drives are exceptionally low-friction. The constant, precise movement of the lead screw drive minimises friction and thus also wear on the components. This ensures a longer service life for the entire lead screw axis.

Structure of a lead screw axis

A lead screw axis contains several complex components that must fit together perfectly. A precise structure plays a key role in the performance and accuracy of the linear axis. Here you can see the most important components at a glance.
Lead screw axis of igus in cross section
1. Bearing
High-quality bearings minimise coefficient of friction and also ensure a uniform rotary movement. As a rule, roller bearings, ball bearings or plain bearings are used here. igus® uses plastic bearings and plastic nuts without lubrication for all linear rails with lead screw drives.

2. Shaft
Linear axes with lead screw drives can, for example, be equipped with unsupported round shafts, and also fully supported with linear rails. With igus® you can choose from three different shaft materials, depending on the application: aluminium, stainless steel or carbon.

3. Lead screw
The lead screw is the actual heart of the lead screw axis. This rotates around its own axis and thus transmits the movement. It is a cylindrical component that is available in a variety of designs. At igus® you will find trapezoidal threads and high helix threads in numerous pitches.
4. Base structure
The base structure of the linear axis with lead screw drive holds the individual components together strongly. This can also be made of different materials such as stainless steel, aluminium, zinc or plastic. We would be happy to work together to find the right material for your application.

5. Lead screw end
The lead screw end helps keep the lead screw in a fixed and strong position. It ensures that the lead screw does not move sideways or wobble while rotating or moving linearly. It therefore plays a very important role in precision.

6. Accessories
Once the lead screw axis is fully assembled, what is left are, of course, the right accessories. Here users can choose between mechanical and electrical options. The classics here are the hand wheel, as shown in the example, along with suitable electric motors.

Different materials within the axis

lead srew

Lead screw materials

igus uses 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 upon request for special applications. For some series, high helix lead screws made of stainless steel are also optionally available and configurable. These options make it possible to achieve significantly higher travel speeds and pitches.
Shaft material

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. We would be happy to work with you to find the right version.
iglidur

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.

* If you want things to go very quickly: You can also find preconfigured linear drives with and without electric motors in our drive technology online shop.
