Maintenance-free heavy-duty and fibre composite plain bearings

igutex TX2

Developed for very high loads

Composite bearings are a combination of different materials. For this purpose, e.g. mineral materials (glass, coal) are woven, combined with synthetic resins and other additives and sometimes pressed together under high temperatures and pressure.

With our igutex plain bearings, a robust fibreglass fabric serves as the outer shell, while an inner layer optimised for sliding properties reduces friction on the shaft.

The combination of these materials results in high-strength composite fibre plain bearings that are primarily used in agricultural, construction and mining machinery. Since our igutex composite bearings contain solid lubricants, they do not require any maintenance or additional lubrication. Incidentally, this also applies to our iglidur heavy-duty plain bearings. These also eliminate the need for regular lubrication, making your bearing points maintenance-free.

What is special about igutex fibre composite plain bearings?

Fibre composite plain bearing structure

Where injection-moulded plain bearings cannot be used due to excessive mechanical loads, wound igutex fibre composite plain bearings play to their strength. They consist of two layers:

1 Gliding layer

The gliding layer consists of a filament fabric with solid lubricants, making the composite plain bearings self-lubricating and maintenance-free with particularly low coefficients of friction.

2 Base layer

The outer layer of igutex slide bearings is made of particularly hard-wearing filament fabrics and serves to protect the tribologically optimised inner layer.

Pulsating loads? No problem.

Brunner Spezialwerkstatt AG uses plain bearings from igus in its slurry spreading systems in order to operate 28 bearing points without lubrication and corrosion. Enormous pulsating forces act on some of the bearing points - an ideal environment for TX1 plain bearings, which can withstand surface pressures of up to 200MPa.

Costs minimised

Thanks to the self-lubricating igutex TX1 fibre composite bearings, crane manufacturer Tan Cang Gantry has been able to reduce costs for its customers without reducing the service life. In addition, maintenance has been reduced to a minimum so that insufficient lubrication no longer poses a risk.

Reliable despite dirt and grime 

The track vehicle from Kässbohrer Geländefahrzeug AG relies on wound igutex heavy-duty plain bearings in the oscillating and tensioning axles. Even in mud, slush, and bog, igutex plain bearings remain reliable.

20 tons load and salt water

The Ship & Yacht Engineering Ltd. A-frame can lift loads of up to 20 tons. Therefore, heavy-duty plain bearings that are suitable for high loads were required. For use on the high seas, they also needed to be weatherproof.

iglidur Q3E plain bearing

iglidur Q3E - High-load plain bearing for large quantities

iglidur Q3E is our heavy-duty plain bearing made from two components with excellent tribological specifications. The sliding surface consists of iglidur Q3 and is surrounded by a high-strength jacket. The combination of both materials ensures high mechanical resilience with low wear at the same time.

SG03 Plain bearing

iglidur SG03 plain bearing with felt seal

The iglidur SG03 plain bearing seals bearing points with its felt seal. This prevents dust and dirt from penetrating the bearing point and damaging it. In laboratory tests, the use of the felt seal increased the service life of the plain bearing by up to 50 times.

iglidur Q2 plain bearing for high load carrying capacity

iglidur Q2 plain bearings represent high load capacities and good abrasion resistance at high loads. The plain bearing offers excellent value for money. Solid lubricants in the plain bearing material lower the coefficient of friction and reduce wear. Q2 plain bearings are specially developed for heavy-duty pivoting applications.

What is special about iglidur plain bearings?

Plain bearing bearing with construction machine

iglidur plain bearings are developed from highly wear-resistant plastics that have very low coefficient of friction. Over 60 different iglidur materials are available and are each developed for special applications. All contain solid lubricants and are therefore suitable for use without additional lubrication and maintenance.

In addition to polymers, iglidur plain bearings for heavy-duty applications contain fibres and fillers, which give them their high wear resistance. This makes them suitable for high forces and edge loads.

Thanks to a large database of test results, the service life can also be determined for various operating conditions.

Agricultural vehicle with Rockinger trailer coupling

Maintenance-free in wind and weather

A customised wear insert made of iglidur material makes lubrication superfluous and thus prevents high costs for the regeneration of the coupling. In addition, no lubricant is released into the environment.

Extended service life in crawler track system

Load with a lot of dirt and moisture. Slyagri Ltd. approached igus with these requirements when they were looking for plain bearings for a crawler track system. Conventional bronze bearings wear out too quickly, so a more durable alternative was needed. Since then, iglidur plain bearings have been successfully in use.

Pulley module

No problem with high loads

The Ets Payant pulley module transports soil from a depth of up to 65 metres to the surface and can lift up to 5 tons of material. This is no problem for the iglidur two hole flange bearings and thrust washers used.

Cultivator from Lemken

Maintenance time saved

Thanks to the self-lubricating iglidur plain bearings, one hour of maintenance time is saved daily at the bearing points of the Lemken cultivator. Due to their stability, the iglidur plain bearings also significantly increase the reliability.
