Reduce costs with
iglidur® plain bearings

Five reasons why you should use iglidur® plain bearings in motor vehicles

1st reason: reduce costs by 40%

Ongoing pricing pressure is forcing OEMs and parts suppliers to optimise their costs continually. Low-cost tribo-polymers are a commonly used alternative to expensive metal bearings.
Today, almost every motor vehicle that is made contains polymer bearings as a substitute for metal plain bearings and rolling bearings. Uses range from seat systems to thermally stressful applications in the engine compartment, in shift forks for gearboxes, in coolant pumps, or in the powertrain.
Why are polymer bearings more cost-effective than metal rolled bearings?

  • Less energy required in the manufacturing process
  • 11,000 litres of crude oil are needed to make 1 m³ of steel; for 1 m³ of plastic , only 1,000 litres of crude oil are needed 
  • Short cycle times during processing
  • Greater amount produced per cycle due to multiple activities in the injection-moulding procedure
  • Due to precise manufacturing, downstream manufacturing stages are usually unnecessary.

2nd reason: save up to 80% weight

Legal requirements are necessitating the continuous reduction of vehicle emissions. One way of achieving this is vehicle weight reduction. This results in a further advantage: less weight leads to less fuel consumption.
A modern iglidur polymer bearing is up to 80% lighter than a conventional metal bearing. The number of bearing points has grown continually alongside the increase in vehicle complexity. This means that weight is an important factor to be considered when the bearing material is selected.
This is where iglidur polymer bearings display their advantage: they weigh less than metal bearings and therefore contribute towards the reduction of carbon-dioxide emissions. In addition, considerably less crude oil and therefore less energy is needed for their manufacture. Even in use, they do not require any additional lubricant.
For alternative drive concepts as well, the advantages of iglidur bearings are decisive. This is where lightweight and extremely quiet components that generate less unpleasant noise during operation and enhance driving comfort are called for.

Reduce weight with iglidur® plain bearings * A conventional metal bearing is up to 80% heavier than a modern iglidur polymer bearing.

3rd reason: reduce noise (Buzz, Squeak and Rattle)

4th reason: self-calibration

5th reason: flexible installation concepts

Freedom of shape in injection-moulding manufacturing makes installation easy

Thanks to our modern injection-moulding method, almost any geometry can be made in the desired iglidur plain bearing. As a flexible iglidur clip bearing, flange bushing or double flange bushing specifically for a quick installation in sheet metal. Individual special solutions made of plastic in the desired shape, quantity and material are also possible. Moreover, we can provide you with your desired special geometry within 48 hours as a sample for your tests.

More on the use of iglidur plain bearings in motor vehicles

iglidur plain bearings are resistant to wear, temperature extremes and oil. This is why they are fitted on belt tensioners in throttle valves and in gearboxes.
