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

igus® linear guides are made from maintenance-free, self-lubricating high-performance plastics. The lubricant is incorporated into the bearing material, making the bearing materials suitable for dry-running conditions. They are maintenance-free for the entire length of their service life. By eliminating lubricants, igus® linear systems are:

Clean and hygienic

Quiet operation

Corrosion resistant

Resistant to dirt, dust and moisture

Design flexibility

Easily configurable online

Product advantages and technical properties

1.1. Resistant against dirt, dust, moisture absorption

Particles are repelled from the contact surface by the movement.

How it works

Resistant against dirt, dust, moisture absorption

Dry-running, without lubrication

drylin® linear bearing systems are designed for dry-running. Applications are protected against contamination with grease or oil. Even applications under coarse dirt and sand arepossible.

igus® tested

Insensitivity to dirt

Dirt particles 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

How it works

Quiet and smooth

Quiet

Since drylin® parts operate as sliding parts, operating noise is greatly reduced when compared to the mechanical rolling of recirculating ball bearings.

igus® tested

Low-noise

The gliding motion is extremely quite 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

How it works

Quiet and smooth

Clean and hygenic

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

Tested

Cleanroom applicable

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 its low installation height, the absence of lubricants and the certification for cleanroom applications by the Fraunhofer Institute.

1.4. Corrosion resistant

How it works

Corrosion behavior

Resistant to corrosion and media resistant

All iglide® 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 drylin® product range also has special purpose materials for permanent use in submerged conditions.

igus® tested

Corrosion-resistant 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 engineering firm decided on the comprehensive use of polymer plain bearings, which reliably operate under these rough environmental conditions. In total, 239 igus® plain bearings were installed in the new machine.

2. Bearing materials

Materials for any shaft material, superior specific wear

How it works

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, iglide® 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 iglide® J, J200 and T500 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 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

Aluminum: 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

How it works

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 65 feet (20 meters). 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 drylin® W.

7. Highly flexible - you determine length and width

Variable width, length, installation type. As fixed and floating bearing systems

How it works

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.

Design tips and rules

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.

How it works

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.
