"Iglidur" plain bearings are already being used, for example, in the lifting arms of front loaders. Igus has the heavy-duty material "Iglidur TX1" in its range for even tougher applications, for example in the construction machinery or agricultural sector, where very high forces act on bearings. This offers extremely high compressive strength and a long service life. It also has high media and temperature resistance up to 170 ° C for a short time.

To save weight, lightweight components are needed that are also very robust. These requirements are fulfilled by the sliding bearing material Iglidur TX1 - especially in applications where very heavy loads are moved. "With static compressive strength up to 200 MPa and dynamic 140 MPa, we can handle many of the heaviest weight applications," said René Achnitz, head of Iglidur's Igus business. At the same time, iglidur TX1 is self-lubricating and dry-running. However, it can be used lubricated in individual cases, for example, when used in applications of the agricultural or construction machinery sector, the grease as corrosion protection for the shaft.

Especially heavily loaded pivoting movements, in which the highest radial loads prevail, can be realized with plain bearings made of this material. Iglidur TX1 combines very good wear and friction values with a high dimensional stability. "Due to the long fiber winding, Iglidur TX1 plain bearings absorb even strong impacts and impacts, while remaining dimensionally stable," says René Achnitz. Therefore, even heavy-duty applications can be equipped with these bearings as an alternative to metallic solutions that always require a permanent lubrication or where a lack of lubrication can cause maintenance and repair costs and production losses.

Due to the fact that the sliding bearings made of Iglidur materials do not need to be lubricated, no dirt can accumulate on the bearing points. Since the material is also very resistant to temperature, chemicals and moisture, corresponding plain bearings can be used in numerous other areas. The low maximum water absorption of under 0,1 weight percent in combination with seawater resistance predestines the bearings, for example, also for maritime applications - even under water.
