What is the best plain bearing for agricultural machinery?

Uwe Sund | 2. May 2020

There must be an answer to this question. After all, there are a limited number of “best Italian restaurants”, “best frozen pizzas” and “best TV series”. And we haven’t even got to narrowing it down. The best Italian restaurant in Bonn? Or in the whole world? The question of the best plain bearing for farm machines is like that.


Are plain bearings with thick walls advantageous in heavy-duty applications?

Uwe Sund | 24. April 2020

I would say that they are not. Metallic plain bearings with relatively thick walls (conforming to DIN 1850, for instance) are used in many heavy-duty applications in agricultural engineering and construction machinery. Typical bearings are steel bushings and plain bearings made of non-ferrous metals (bronze = copper + tin, brass = copper + zinc), but […]


How large is the largest igus plain bearing? … And if that’s not enough?

Uwe Sund | 20. April 2020

Large bearing diameters tailor-made at an off-the-shelf price! The largest selection of different dimensions is offered by “the generalist” iglidur G. The smallest bearing has an inner diameter of 3mm (smaller inner diameters are available for other iglidur materials). The largest inner diameter of an igus catalogue part is 195mm. Part No.: GFM-195205240-65 (Outer diameter […]


Maintenance of plain bearings … Is maintenance-free the same as dry operation?

Uwe Sund | 16. April 2020

Maintenance is a central point when operating machines. On the one hand, this ensures operational safety. On the other hand, maintenance is associated with expenditure. This expenditure is divided up as follows: The machine is at a standstill during maintenance. Depending on the machine, this is expensive. A construction machine cannot be rented. And problematic […]


Shaft corrosion can cause bearing wear – that is not immediately obvious

Uwe Sund | 2. April 2020

Case study There is little doubt that a shaft damaged by corrosion has a negative effect on the bearing point. It is especially obvious that the shaft is damaged when the corrosion is easy to see – and the surface apparently has already disappeared. But appearances can be deceiving. And that leads to a search […]
