Heavy duty and fibre composite bearings
Self-lubricating, maintenance-free 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 bearings that have been developed for very high loads and primarily used in agricultural, construction and mining machinery. As our composite bearings contain solid lubricants, they do not require any maintenance or additional lubrication.
Additionally to the composite bearings, we have a large range of plastic bearings that are suitable for heavy duty applications.
What is special about igutex fibre composite bearings?
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 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.

Frequently asked questions
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.
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.
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!
You can purchase industrial-grade heavy duty bearings from a range of places, most bearing companies will have a range of bearings for this and you can buy them from us
Main types of bearings for extreme loads tend to be metal composite, composite like our igutex range, bronze or brass.
