Lubrication-free bearing technology for cargo bikes
Cargo bikes have become a popular alternative to cars, especially in cities, because they are far less expensive, have no exhaust fumes and traffic jams can be easily avoided. An electric motor also makes driving easy, even with heavy loads and longer distances. To ensure that they remain functional over a long period of time, every day and in all weather conditions, cargo bikes should be equipped with robust and low-maintenance components. Our dry-operating, plain, spherical and linear bearings made of high-performance plastics make an important contribution to this.
1 Suspension seat post
Whether in suspension or Vario seat posts - plain bearings made of iglidur material play out their advantages here. In suspension seat posts, it is not only the freedom from lubrication and the weight reduction compared to metal alternatives, but also the vibration dampening specifications of the plastic material. This brings a clear plus in riding comfort. Plain bearings made of iglidur P are ideal for the application in the seat suspension, prolong product service life, and the cyclists can also sit comfortably on the saddle for a long time.

Best suspension on the saddle with maintenance-free iglidur flanged bearings
For their G.2 suspension parallelogram seat post, the designers at by.schulz were on the lookout for a suitable material for the four bearing points at the pivot points. The bearings are subjected to high stresses on a small section during spring deflection. With brass bushings, which had been used in the first series, one was dissatisfied in view of the constant lubrication effort. After a series of tests, flanged bushings made of the material iglidur W360 convinced the developers: they are maintenance-free, have a long service life, a low coefficient of friction and are insensitive to edge pressure.

5 Guide bar
As an extension of the handle bar, the guide bar must ensure that the bike moves in the desired direction. Therefore, it requires not only permanent precision, but also stability - two criteria that can be fulfilled with our igubal rod end bearings. Placed near the front wheel hub, the joints are regularly exposed to wetness, dust and mud. Conventional rod ends need to be cleaned and lubricated regularly, otherwise they start to squeak and corrode and the guidance becomes wobbly and inaccurate. With our dry-operating spherical plain bearings, you do not have this problem. The steering remains consistently precise with no maintenance required.

Strong spherical and plain bearings in heavy-duty e-cargo bike
More and more logistics companies are bringing packages to people's doorsteps on e-cargo bikes. Above all, the bikes have to be robust and low-maintenance. The company b&p engineering therefore relies on bearings from igus in its heavy-duty model. "A good plastic bearing can withstand what a steel bearing can," says Vincent Okroy, designer of the vehicle. In the handle bar, wear-resistant igubal EGLM spherical bearings contribute to a higher durability of the cargo bike, they reduce maintenance thanks to their dry operation and additionally score with their lightweight feature. The advantages are also used by b&p in the trailer coupling, where iglidur X bushings with very high compressive strength are used.

12 Stand
On the cargo bike the stand is located under the box and directly behind the front wheel. This leads to the bearing point being exposed to particularly high levels of dust, dirt and water. On conventional lubricated bearings, the dirt adheres to the bearing point. This not only impairs the sliding properties of the bearing, but also causes it to be scratched from the inside, resulting in clearance. The fact that the stand squeaks, wobbles and rattles over time can be avoided with our lubrication-free bearings. Our low-cost bearings made of iglidur R material are ideal for this application.
