Igus offers a wide range Lagertechnik made of plastic, including various, lubricant-free linear bearings Executions. They all offer a long service life, are maintenance-free and, depending on the design, provide users with further advantages. So z. B. the linear bearing made of Iglidur W360 High performance plastic for precise and easy movements in the Linear Technology. In the following we present you these and other innovations of Igus linear bearing technology:

All-plastic linear bearings for fast movements

July 14.07.2021, XNUMX | Igus developed the first Drylin W linear bearing made of tribo-polymers specifically for this purpose slight linear movements developed. It weighs only 10 g. This makes it very suitable for transport applications. The linear bearing can be installed quickly, it is vibration-damping and lubricant-free. It is very inexpensive due to the injection molding process. The design, optimized for injection molding, also reduces weight, which in turn significantly reduces the drive energy of the linear system.

The Drylin W linear bearing consists completely off Plastic. The linear bearing foil and the linear housing are combined in one component. This simplifies handling from storage to assembly. In contrast to classic linear bearings in a metallic housing, the all-plastic bearing can save up to 84% in weight. Less mass has to be moved. This saves motor power, power and energy consumption. Especially for beginners who need a simple linear guide for adjustment tasks in e.g. B. desktop devices, cameras, monitors or Sensors need, the slim all-plastic bearing offers several advantages.

Black linear bearings with the lowest friction

The linear bearing consists of the tribologically optimized high-performance plastic Iglidur JB. That makes it lubricant-free, maintenance-free, dust- and dirt-resistant and durable. The black one material offers the lowest coefficients of friction in dry running. The stick-slip tendency is very low. The plastic bearing can easily handle loads of up to 25 N. Tests have that shown in the in-house 3800 m² laboratory at Igus in Cologne. The linear bearing is also robust and impact-resistant, while it absorbs and dissipates vibrations in an elastic and dampening manner.

The new linear bearing is on Drylin W Single rails and double rails mountable. If you are looking for an inexpensive linear guide, the clear anodized Drylin W aluminum rails WS-CA from the manufacturer are ideal. In combination of the silver aluminum with the black color of the bearing, users receive a complete solution in a simple, elegant design.

Precise and rigid linear bearings for round shafts

May 21.05.2021, 360 | The new linear bearings from the WXNUMXCM series from Igus can be moved with high precision on round shafts. The polymer linear bearings enclose an aluminum housing. A thin sliding film ensures quiet and easy running with high rigidity. The linear bearings have hardly any play and enable precise movements. Thanks to the use of Iglidur W360 The user does not need to lubricate high-performance polymers. The dimensions of the new series match metallic ball bushings and can be converted 1: 1.

The topic often plays a role when using linear guides precision play an important role if they are built into a microscope stage or X-ray machine, for example. The linear plain bearing version W360CM is very precise and stiff on Drylin R round shaft guides. The long-life sliding elements of the linear bearings ensure thin walls and high strength.

Im Injection molding process the bearings are manufactured cost-effectively from the high-performance polymer Iglidur W360. Thanks to the material, they run very quietly and easily on the shaft. you carry Temperatures between 0 ° and 50 ° C was standing. The thin wall thickness and higher strength ensure that there is little bearing play at the working point because the elasticity is reduced. Thanks to the lack of lubrication, the new linear bearings are also free from contamination and do not require maintenance.

Efficient linear guide with lubrication status monitoring

Linear bearings made of polymer convince in the test

The W360CM linear bearings can be easily installed in all Drylin housings and standard receptacles for linear ball bearings. So let yourself Convert ball-based solutions 1: 1. The structure of the new linear bearings is simple: sliding foils are pressed into the housing until the pre-stressed snap-in hook dips into the groove.

The foils are thus secured against migration under high loads and temperatures. Tests at igus were convincing. In gauge measurements to check the bearing clearance and the precision, it was shown that the W360CM version performs far better than coated linear bearings.

Linear plain bearings as a better alternative to linear ball bearings

July 02.07.2017, XNUMX | Igus also calls it “Slip dry“: The storage of shafts or axles in the Linear Technology and Drive Technology. As with all camps, the principle of action is basically between the two types Sliding and rolling bearings distinguished. While ball bearings are often still preferred as the measure of all things, thanks to innovative high-performance plastics there is an ever-increasing number of applications which Linear bearings speak.
