Slewing ring bearings made of wood and plastic
With a slewing ring bearing made of WPC (wood-plastic composite), Igus is taking a further step forward in the integration of renewable raw materials in industrial production, using 50% wood and 50% high-performance plastics for the lubrication-free slewing ring bearing.
How can renewable raw materials also be used sensibly in industry? Igus asked itself this question and developed an 'iglidur PRT' slewing ring bearing made of wood-plastic composite (WPC). "As a plastics expert, we are now also venturing into the wood sector. Last year, we presented wooden shafts as possible running partners for our linear guides for the first time. This year, we are integrating wood directly into our products," explains Marc Trenkler, Product Manager for slewing ring bearings at Igus. The company relies on its injection molding. The slewing ring bearing is made of WPC, a mixture of wood fibers and high-performance plastics. The materials incorporate solid lubricants that make the slewing ring bearing smooth-running, lubrication-free and maintenance-free. The wood content gives the whole thing a natural look. Both the housing and the component are made of the WPC material. Only four screws are needed to join the two parts together.
Developed specifically for the popular 'PRT 02' size, the slewing ring bearing is an equally priced alternative to the low-cost PRT made of solid plastic. It enables simple adjustments, for example in furniture technology, and at the same time offers a robust design that meets the requirements of various applications. The CO2 footprint is stated as 0.0577 kg. By comparison, the 'PRT-02-30-ECO', which already consists of 97% regranulate, has a CO2 equivalent of 0.819868 kg.
