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:
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.
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.
Previously, bushing contamination would regularly result in blockages, even breaking the shaft. Thanks to drylin®, the machine now operates completely free of malfunctions.
Since drylin® parts operate as sliding parts, operating noise is greatly reduced when compared to the mechanical rolling of recirculating ball bearings.
The gliding motion is extremely quite and only a light friction noise is audible.
Despite its relatively high travel speed, the elevator moves with very low-noise. The smooth and quite running led to the use of drylin®.
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.
drylin® guides reveal a distinct applicability for cleanrooms. The following drylin® guides from igus® were tested: N40, W10, T25 and T30.
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.
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.
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.
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.
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® 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.
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.
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
Guide carriages are available from stock in various standard lengths, e.g. 100mm , 150mm und 200mm.
We will cut the guide rails to your desired length. There is no minimum length and also no maximum stroke length.
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.
Due to the price advantage in combination with the resistance against dirt and dust, the customer opted for drylin® W.

drylin® W linear guides support highly flexible uses. Alignment and parallelism errors can be compensated by using floating bearings.
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.
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.
The application of non-hardened shafts is possible.
Even non-metallic counter-partners are usable
A galling is completely excluded.
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.
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.
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.
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.
In an effort to continuously improve our product range and to address your specific needs, we are reviewing various shaft materials and extensively testing these with a variety of bearing solutions in our igus® dry-tech lab.
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.
In addition to the classic guide, consisting of guide rail and guide carriage, the linear system can also be customised to suite your needs.
drylin® W is available as a measurement system unit, with manual clamp, clearance adjustment, in stainless steel, as a mono slide and with hybrid bearings.
Individually adjustable bearings, manual clamps, hybrid carriages "Rolling instead of gliding" and more ensure shock-free, lubricant-free gliding in camera systems.
Based on our drylin® W linear construction kit, we can also provide drive units based on a lead screw or timing belt. The systems can be customised to suit your needs.
