Automotive plastics brochure Railko has produced a six-page colour brochure on the applications and technical advantages of its advanced engineered plastics for the automotive industry. Railko low friction thermoplastics are commonly used in steering and suspension applications where low friction and noise elimination are required. Moulded and extruded thermoset materials are used in steering and transmission applications where dimensional accuracy and stability are needed. Railko was recently awarded the Ford European Automotive Operations QI Preferred Quality Award and has proved its dedication to quality by also achieving BS5750, EN29002, ISO9002 and Ministry of Defence AQAP 4 quality awards. Free copies of the brochure are available from Railko Limited, Boundary Road, Loudwater, High Wycombe, Buckinghamshire HP10 9QU, UK.
Bearing damage detection method announced A method to detect rolling bearing damage has been developed by the SKF Engineering and Research Centre (ERC). The SEE (Spectral Emitted Energy) technique provides industry with a method to detect bearing damage at a very early stage. It has been shown to be a very sensitive method for monitoring bearing condition and is insensitive to most machine noises. Practical trials on papermaking machines, compressors, pumps and separators have shown that the SEE technique can be used to correctly identify incipient bearing damage in good time before any resultant failure can occur. New monitoring instruments have been developed to allow the practical application of the SEE technique. The range extends from hand-held units to FFT analysers and complete online systems.

BP Oil has presented its first-ever Award to Excellence, and Geoffrey Newby, National Power's General Manager North, is the proud recipient. Mr Newby won the inaugural award for his work on water induction and the problems it poses for steam-powered plant, ttis studies were based on the Drax power station in North Yorkshire. Making the presentation were Richard Wyatt, President of the Institution of Plant Engineers, and Jack McArthur, representing BP Oil. The award, consisting of a handsome plaque and a cheque for £1000, was presented at the Industrial Maintenance Management and Engineering Exhibition and Conference, held recently at London's Olympia. BP Oil and the Institution of Plant Engineers have co-operated to create the annual award, aimed at highlighting the vital role played by engineers in keeping society working. The BP Oil A ward to Excellence is open to any engineer engaged in plant, works or maintenance engineering in the manufacturing, construction, process or service industries. It is judged on the contribution candidates make through their everyday work to the benefit of their organization or to the public at large. The signals produced by bearing damage are known to occur over a wide range of frequencies. The SEE technique utilizes the frequency range around 300 kHz for the analysis of the bearing signals. At this high frequency the general machine vibrations are low so that the signals emitted by the bearings are more easily identified. The signals are electronically processed so that they are transformed down into the normal frequency range. Tests at E R e claim that the signalto-noise ratio is improved using this method compared with other equipment on the market.
The signal from the sensor is filtered at 300 kHz and demodulated. Any repetitive components in the original signal remain unaltered. Further evaluation is carried out by calculating the spectrum and comparing the spectral lines with calculated bearing damage frequencies or with trending signal parameters such as the RMS value. Various condition monitoring methods for bearings are available on the market but SKF claim that none of these methods is successful over a wide range of applications.
