Maintenance-free heavy-duty and fibre composite plain bearings

Self-lubricating heavy duty bearings

Composite bearings are a combination of different materials. Mineral materials are woven with fibres, combined with synthetic resins and other additives and then 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 have been developed for very high loads and primarily used in agricultural, construction and mining machinery. As our igutex® composite bearings contain solid lubricants, they do not require any maintenance or additional lubrication.

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, which makes 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.

igutex® fibre composite plain bearings are used here

Reliable despite dirt and grime

All-terrain vehicle

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

More on the application

Lubrication costs saved

Oscillating axles

The Demarko company uses igutex® composite bearings in oscillating axles for semi-trailers. Since the fabric bushings do not have to be lubricated and are part of the igus standard range, Demarko was able to reduce production costs.

More on the application

20 tons load and salt water

A-frame

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

Frequently asked questions

Do composite bearings require lubrication?

Like all our bearings, igutex® composite bearings require no lubrication as this is already built into the ‘gliding’ layer. igutex® will also accept lubrication, should this be necessary for your application.

What sizes are igutex® composite bearings available in?

Our composite bearings are available as a sleeve bearing with an internal diameter as small as 20mm up to whatever size you need! They can also be manufactured as a thrust washer with gliding surfaces on one or both sides.

Can igus® composite bearings be machined?

Yes, igus® can provide igutex® composite bearings to your required specification, we are also able to provide guidance on machining – just talk to one of our engineers!
