Maintenance-free iglidur® plain bearing made of plastic

iglidur G and iglidur J plain bearings

iglidur plain bearings do not require additional lubricants. They are therefore maintenance-free and represent a cost-effective alternative to metal plain bearings. They are available here in various types and in more than 10,000 sizes in our plain bearing online shop. The iglidur materials specially developed by igus enable a wide range of applications for our slide bearings in a wide variety of industries. For example, for use at high temperatures, contact with food or chemicals and under high loads.

What you will find on this page

PFAS and PTFE-free plain bearing bushes

Due to the current discussion about a PTFE ban, we have put together all the important information about PTFE in relation to our plain bearings. Here you will also find a list of all iglidur materials that do not contain PTFE.

The advantages of our plain bearings at a glance

iglidur-plain-bearings-maintenance-free-and-lubrication-free

Lubrication and maintenance-free

Due to the self-lubricating effect iglidur plastic bearings do not require any additional lubricants. How it works? Our iglidur materials contain solid lubricants, millions of which are contained in the material. These lubricants are released in tiny amounts and thus lubricate the bearing point. Therefore there are no problems with insufficient lubrication and only minimal maintenance requirements. 

Cost down

Cost-effective

Our self-lubricating plain bearings reduce your maintenance costs and completely save additional expenses for lubricants - with no minimum order quantity up to high volume. Our plastic plain bushes are up to 89% more cost-effective than plain bearings made of steel or bronze. 
Example: €2.37/piece versus €0.25/piece

iglidur plain bearing with chemical resistance

Resistant to chemicals and media

Our range includes a variety of different slide bearing plastics, which are e. g. characterised by high chemical or temperature resistance. Daily cleaning with aggressive cleaning agents and high pressure are therefore not a problem, since plastic bearing bushes from igus do not require any additional lubricants that would otherwise be washed out during cleaning.

iglidur-plain-bearings-for-heavy-duty

Suitable for high loads

Our plastic plain bearing bushes are used e. g., in construction and agricultural machinery. In both cases, very robust plain bearing materials are required that can withstand not only dirt but also high loads. For this purpose, we offer on the one hand self-lubricating plain bearings made from our iglidur materials and for exceptionally demanding cases igutex plain bearings, which are reinforced with high-strength fibre-glass fabric.

Frequently asked questions about igus plastic plain bearings

How is the bearing clearance for plastic plain bearings determined?

Plain bearing bushes made of plastic require a certain amount of bearing clearance to compensate for various environmental factors. Some plastics absorb a relatively large amount of water or expand with increasing temperature. When this happens, the clearance decreases. If the clearance is dimensioned too small from the outset, it will jam. The shaft runs sluggishly, which can lead to altered haptics or machine performance. The bearing wears out faster. In the worst case, the bearing point even breaks down into its individual parts. It is therefore necessary to find a middle ground. As much bearing clearance as necessary, as minimal as possible. The lower the bearing clearance is to be set, the more precisely the environmental parameters should be taken into account and the more value should be placed on the most accurate and strict quality specifications possible.

How are our self-lubricating plain bearings constructed?

iglidur plain bearings consist of three main components:
1. Base polymers,
2. Fibres & fillers and
3. Solid lubricants. 
The base polymers are decisive for the wear resistance of the iglidur materials. They ensure that the solid lubricants are not subjected to excessive surface pressure. Fibres and fillers reinforce the materials so that they can withstand high forces or edge loads and can be used under continuous stress. The solid lubricants lubricate the iglidur plastic plain bearings independently and thus reduce friction. They are distributed throughout the material in the form of microscopic particles.
