Service life calculated in advance
igus calculated the service life of the slewing ring bearing for EEVE in advance using a free online tool: the so-called
iglidur PRT expert. All data collected in the igus test laboratory on the service life of slewing ring bearings flows into this tool and thus enables an accurate prediction of the product service life. "In our case, the service life far exceeds our design requirements," notes Gilmartin. "The PRT slewing ring bearing is the only bearing we wanted to use. It offers a clear price advantage compared to ball-bearing slewing rings," he adds. In addition, ball bearings would have to be replaced much earlier due to dirt and dust pollution and must be lubricated regularly. "Even under harsh environmental conditions, our slewing ring bearings allow for robust and maintenance-free operation for at least ten years. When using EEVE, the service life is 90 years," explains Joren Kestens, who works in the field service at igus.
