Maintenance-free iglidur® plain bearings made of plastic

Bearings serve to prevent direct contact, e.g. between shaft and mount, so that they do not wear out. Most bearings must be lubricated regularly to ensure fault-free function. iglidur® plain bearings do not require any additional lubricants. They are therefore maintenance-free and represent a cost-effective alternative to metal plain bearings. They are available in various types and in more than 10,000 sizes, here in our online bearing shop. The iglidur® materials specially developed by igus® enable a wide range of applications for our plain bushings in various industries. For example, for use at high temperatures, in contact with food or chemicals and under high loads.

The advantages of our plain bearings at a glance

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

Lubrication and maintenance-free

Through 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 effort.

Cost-effective

Our self-lubricating bushes reduce your maintenance costs and completely eliminate additional expenditure on lubricants - from no minimum order quantity to high volume. Our plastic sliding bushes are up to 89 % cheaper as plain bearings made of steel or bronze.
Example: 2.37 €/piece against 0.25 €/piece

iglidur plain bearing with chemical resistance

Resistant to chemicals and media

Our range includes a large number of different sliding bushes-plastic which are located z. g. characterised by high chemical or temperature resistance. Daily cleaning with aggressive cleaning agents and high pressure is therefore no problem, as plastic bearing bushes from igus no additional lubricants that would otherwise be rinsed out during cleaning.

Suitable for high loads

Our plastic plain bearings are used e. g., in construction and agricultural machinery. In both cases, very robust materials are required which, in addition to dirt also withstand high loads. For this purpose, we offer self-lubricating bushings made from our iglidur® materials and for particularly demanding cases igutex plain bearings which with high-strength glass fibre fabric are reinforced.

Frequently asked questions about our products

How is the bearing clearance for plastic plain bearings determined?

Plain bearing bushes made of plastic require a certain 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 do not come under too much contact pressure. Fibres and fillers reinforce the materials so that they can also withstand high forces or edge loads and can be used under continuous stress. The solid lubricants the iglidur® plastic bushes lubricate independently and thus reduce friction. They are distributed throughout the material in the form of microscopically small particles.
