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

Yvan Cao | March 1, 2022

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…

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

Yvan Cao | November 11, 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 depending […]


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

Yvan Cao | November 4, 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 for […]


The right shaft for tough outdoor use – if the plain bearing is outdoors.

Yvan Cao | October 28, 2020

Everyone knows that the agricultural and construction machinery sector require lots of care. Dirt, moisture, corrosion, the complete package. Whether a combine harvester, tractor, concrete mixer, plough or mobile crane – here everything is in the same boat. Metallic plain bearings are always lubricated – at least they should be if they are to function. […]

What is the best plain bearing for agricultural machinery?

Yvan Cao | October 21, 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 […]


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

Yvan Cao | October 14, 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 205mm, flange […]


Under Heavy Load Application Conditions–Study on Maximum Service Lives of Shaft and Sliding Bearing

Yvan Cao | September 30, 2020

In a motion structure, a shaft and a bearing constitute an operating unit. In this sense, wear and friction values need to be evaluated from an overall perspective. To optimize lives, materials of the shaft and the bearing need to be perfectly coordinated, which is a main challenge for bearing manufacturers today. For the shaft, […]

The advantages of iglidur in the application of air valve products

Yvan Cao | June 1, 2020

There are “invisible” pipelines in high-rise buildings—air conditioning ventilation system and fire safety system, which coordinate the temperature adjustment to ensure a good air environment in the building, or to reduce property losses in fire and ensure personal safety. Valves are a key component of the system. This article will introduce you to the application […]
