drylin® SLW linear modules… 7 installation sizes, custom configurable, delivered in 2-4 days

Glides instead of rolling! Lubricant-free through dry-tech® polymers

igus® SLW linear modules are based on the drylin® W linear construction kit and on maintenance-free and self-lubricating dry-tech® high-performance plastics. The lubricant is incorporated into the bearing material, rendering the bearing materials suitable for dry-running conditions, e.g. they are maintenance-free for the entire length of their service life. Ready-to-install linear modules are available in 2-4 days.

Take advantage of the technical benefits of our maintenance-free drylin® drive technology.

1.1. Resistant against dirt, dust, moisture absorption

Particles are repelled from the contact surface by the movement.

Details of working principle

Resistant against dirt, dust, moisture absorption

Dry run, without lubrication

drylin® linear bearing systems are designed for dry-running. All applications are therefore protected against contamination with grease or oil. Even the application under coarse dirt and sand is possible.

igus® tested

Insensitivity to dirt

Dirtparticles are repelled from the contact surface by the movement itself. Here the front side of the gliders works like a wiper. The contact surface remains clean.

Application example

Diaper production systems

The plants process super-absorbers and pulp that generate relatively high dirt and dust exposure. As superabsorbent polymers also behave similarly to sand, dirt accumulates as a result of friction.

1.2. Low noise

Details of working principle

Quiet and smooth

Low noise

The operating noise is also greatly reduced by switching the operating principle from rolling to gliding. There is no mechanical rolling up of hard gliding partner and no ball collisions that cause loud noises.

igus® tested

Low noise

The gliding motion is extremely low noise and only a light friction noise is audible.

Application example

Edge taker

Format adjustment of the sensors for web edge detection and print mark recognition through drylin® SLW linear table solution with position indicator and hand wheel (convenient and reproducible positioning from outside)

1.3. Clean and hygienic

Details of working principle

Quiet and smooth

Clean and hygenic

The dry-running properties of iglidur® plain bearings are not only advantageous in contaminated environments. The absence of lubrication is also an important criterion in applications with elevated requirements for hygiene and purity.


clear room applicable

The tested drylin® guides reveal a distinct applicability for cleanrooms. The following drylin® guides from igus® were tested: N40, W10, T25 and T30.

Application example


The drylin® spindle lift table with position indicator and handwheel is used in a coder to label cheese because of its freedom from lubricants.

1.4. Resistant to corrosion

Details of working principle

Corrosion behavior

Resistant to corrosion and media resistant

All iglidur® plastic plain bearings are by their nature corrosion-free. There are also special purpose materials, which can be used against caustic solutions, acids, cleaning agents, etc., and, due to their media resistance, can be used even under the most adverse conditions. - The product range also has special purpose materials for permanent use in submerged conditions.

igus® tested

Resistant to corrosion and media resistant

Corrosion-free unit

The resistance of linear bearing systems is equally dependent on the counter partner. The igus® construction kit can be delivered complete as a corrosion-free unit made from stainless steel.

Application example

Inspection systems

drylin® SLW or SHT linear tables solve the height adjustment of cameras and sensors

2. bearing materials

Materials for any shaft material, superior specific wear

Details of working principle

Low wear - plain bearing liners made from high-performance polymers

High Performance Polymers

SLW linear modules can be configured and supplied to match the application with respect to the plain bearing materials. Standard configurations for SLW systems include bearings made from wear-resistant iglidur® J/J200 materials. Bearings and lead screw nuts made from iglidur® X materials in combination with stainless steel are the best option for applications that require extreme chemical resistance. The FDA compliant iglidur® A180 material is particularly well suited for applications in the food/pharmaceutical sectors.

igus® tested

Extensive lab tests and years of field experience have shown that iglidur® J, J200, X and A180 are ideal materials for most linear applications due to their favourable wear and friction properties.

3. Selecting the ideal housing bearing material

Various housing bearing materials available

Zinc die-casting: cost-effective standard bearing

Aluminium: low component weight

Stainless steel: corrosion-resistant and also for high temperatures

Turn-to-fit mechanism: Manual adjustable clearance by „Turn-to-Fit“ function with allen key

4. Thread selection

Thread types

Low wear - plain bearing liners made from high-performance polymers

Trapezoidal threads

Standard configurations on SLW linear module are equipped with single start trapezoidal lead screws and are self-locking. This means that the flank angle and the sliding friction prevent movement of the nut or the lead screw without the application of outside forces. The carriage remains in the selected position. Lead screws made from C15 steel, corrosion-resistant VA (1.4301/1.4305), and coated aluminium are available as counter-partners for drylin® trapezoidal lead screw nuts.

Thread types

Steep thread

drylin® linear modules with high-helix lead screws can be installed for fast adjustment and positioning tasks. High-helix lead screws are made from corrosion-resistant stainless steel (1.4021) and do not have a self-locking feature. This allows them to be used for applications where linear carriages are quickly moved manually on demand.

Application example

Format adjustments

Application in the glass industry Format adjustment on conveyor for separation of bottles.

5. drylin® W rail profiles

... Aluminum hard anodized
... Stainless steel (size 1040 & 2080)

Details of working principle

Low wear - plain bearing liners made from high-performance polymers

Optimum operating properties

Linear modules of type series SLW, SAW and ZLW are based on the lubricant-free drylin® linear construction kit. The extremely torsion-resistant aluminium profiles are produced on extrusion presses. The surface is hard-anodised and is characterised by good wear properties, high chemical resistance and a high degree of hardness. As a counter partner to our dry-tech® high-performance polymers, they ensure superior operating characteristics, are predictable and have a long service life.

Application example


Stainless steel SLW modules based on guide shafts made from V4A (1.4571) materials are available for environments that require extreme corrosion-resistance.
