Eco benefits of plastic plain bearings

Eco benefits of plastic plain bearings
A study has found that no less than half of all machine lubricants currently used seeps into soil and waters or evaporates into the atmosphere. According to a research team of chemists, mechanical engineers and environmentalists from the RWTH in Aachen, the estimates for Germany alone consume 250,000 tonnes per year. This corresponds to the amount required to fill 8,000 tankers.

The tribo-optimised Iglidur plastic plain bearings from Igus require neither oil nor grease. They are lubricant-free, so that no contaminants escape into the environment. Due to continuous advanced developments the bearings specialist Igus now supplies alternatives more in line with environmental considerations for more and more applications that work with lubricated metallic plain and rolling bearings. 

The energy balance for the manufacture of plastics is very positive. Whereas the energy from 15 litres of oil is necessary to produce 1 litre of aluminium, and 1 litre of steel requires 11 litres of oil, the production of 1 litre of plastic only needs an average of 1.8 litres of oil. As far as annual worldwide oil requirements are concerned, the production of plastics only requires 4 percent. This value will probably continue to decrease, since the vegetable production of polymers is making great progress.

Not only will the incorporated solid lubricants make Iglidur polymer plain bearings ecologically valuable. The lightweight bearings will also help to reduce fuel consumption and carbon dioxide output in, for example, vehicles or aircrafts. Basically the reduced weight leads to lower masses and subsequently lower energy consumption. The high chemical resistance of plastic bearings is another positive ecological aspect, because metals are often coated to achieve this effect.
