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
  • Available from stock
  • 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.

    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.

    9. Hard-anodized aluminum rail

    How it works

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

    igus® plain bearing materials are matched to their counter partner with respect to friction and wear characteristics. One attains the longest service life in combination with anodized aluminum. The function and service life of your application can be calculated on-line via freely accessible service life calculation programs.
