How is the bearing clearance for plastic bearings determined?

Plain bearings 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 as the temperature rises. When this happens, the clearance decreases. A clearance that is too low from the outset results in jamming. 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 can even disintegrate into its individual parts. It is therefore important to find a balance: As much bearing clearance as necessary, as little 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 and 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 microscopically small particles.
