Countless design options on the basis of the drylin® W linear guide construction kit

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

igus® linear guides are made from maintenance-free, e.g. self-lubricating 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. By eliminating lubricants, igus® linear systems are

Modular system

Use the technical product advantages of our maintenance-free drylin® W linear construction kit:

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

Concrete cutting machine

Previously, bushing contamination would regularly result in blockages, even breaking the shaft. Thanks to drylin®, the machine now operates completely free of malfunctions.

1.2. Low noise

Details of working principle

Quiet and smooth

Quiet

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

Elevator system

Despite its relatively high travel speed, the elevator moves with very low noise. The smooth and quite running led to the use of drylin®.

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.

Tested

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

Blister machine feeding system

Specific advantages of the drylin® W linear guide system are the low installation height, the absence of lubricants and the certification for cleanroom applications by the Fraunhofer Institute.

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

Leather splitting machine

In the development of the machine, the responsible engineering firm Dr. Dorstewitz decided on the comprehensive use of polymer plain bearings, which reliably operate under these rough environmental conditions. In total, 239 igus® plain bearings are installed in the new machine.

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

Depending on their application, linear guides can be adjusted in regard to the plain bearing material. For instance, iglidur® A180 was developed for applications that require an FDA compliant solution.

igus® tested

Low wear

igus® provides various materials for gliding elements and counter partners for linear systems. Extensive lab tests and years of field experience have shown that iglidur® J, J 200 and X are the ideal materials for most linear applications due to their favorable wear and friction properties.

Application example

Filling-shoe mechanism in a compaction unit

By changing over to the drylin® R linear plain bearing, the maintenance rate of this compaction unit could be extended by 2 years, despite high stressing from powder particles and abrasive agents. The previous recirculating ball-bearing solution necessitated a replacement of bearings and shafts every 2 to 3 months due to worn shafts.

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. Selecting the ideal carriage length

Guide carriages are available from stock in various standard lengths, e.g. 100mm , 150mm und 200mm.

5. Various rails available, various diametres and versions

Details of working principle

Various rails available

Various rails available

We will cut the guide rails to your desired length. There is no minimum length and also no maximum stroke length.

igus® tested

Maximum stroke lengths

Guide rails can be connected in series, since the glide element can travel over the rail joints with ease. This facilitates stroke lengths of more than 20 metres. Assembly is simplified by the distinctive joint marking provided at the factory.

Application example

Glass cutting machine

Due to the price advantage in combination with the resistance against dirt and dust, the customer opted for the drylin® W.

Details of working principle

Highly flexible - you determine the length and width

Highly flexible installation

drylin® W linear guides support highly flexible uses. Alignment and parallelism errors can be compensated by using floating bearings.

igus® tested

Floating bearing for guide system

There is a suitable fixed-/floating-bearing solution for every installation location, whether it be horizontal, vertical or lateral. This installation method prevents a sluggishness and/or a jamming of the guide with parallelism deviations between the guides.

Application example

Fitness equipment

Fit-Equip sought for cost-efficient solutions to replace the previously employed guide systems. Besides an appealing design, the linear guide should be additionally quiet and absolutely lubricant-free. Guide systems from the drylin® W modular kit system were selected.

8. Surface contact

No point loads, as is for instance the case with recirculating ball bearing systems.

The application of non-hardened shafts is possible.

Even non-metallic counter-partners are usable

A galling is completely excluded.

Details of working principle

Surface contact

Surface contact

The use of liners made from high-performance plastics allows the plain bearing to be in contact with the shaft across the entire surface. Thus a considerably larger contact surface becomes available resulting in a much lower surface pressure.

igus® tested

Optimum load distribution due to larger contact surface

Optimum load distribution

Because of the large surface contact in comparison to the point load on a recirculating ball bearing guide, softer, frequently also more cost-effective shaft materials (e.g VA) can be used in addition to hardened shafts.

Application example

Presses

The durability of the steel shafts in these presses and separators has increased at least four-fold, therefore not only highlighting the technical advantages of lubricant-free linear guides, but also making an investment into this equipment a good financial proposition.
