Corporation (UK) Ltd offers an extensive range of super-precision bearings for a variety of applications, including aerospace, turbomolecular pumps, medical instruments, machine tool and motorsport.
4 In arduous, safety-critical applications such as aerospace systems, stand- alone and integrated special bearing designs can significantly improve system cost, performance and operating life, says Gary Hughes.
4 Lors d’applications ardues ou critiques du point de vue de la sécurité, comme les systèmes de l’aérospatiale, les systèmes de roulements spéciaux seuls ou intégrés peuvent considérablement améliorer les coûts, la performance et la durée de vie du système, selon Gary Hughes.
4 Bei mühseligen, sicherheitskritischen Anwendungen wie Luftfahrtsystemen können spezielle allein stehende und integrierte Auflagerentwicklungen die Systemkosten deutlich senken, die Leistung verbessern und die Lebensdauer verlängern, sagt Gary Hughes.
Special bearing designs provide benefits in harsh, demanding applications
P
ressure to reduce costs in all areas of manufacturing means that the integration of bearing systems into mating components is becoming more common. The
resulting assemblies are neater, more compact, faster to put together and offer the additional benefits of reducing space and mass, whilst resolving the issues of tolerance stack-up. The designs of bearings used in these
integrated assemblies are in many cases special, calling upon manufacturers to provide the highest levels of innovation and manufacturing excellence in supplying custom engineered solutions to what are often some of the most arduous operating conditions encountered by any type of machine or equipment. Barden is at the forefront of this design
transformation, producing both standalone and integrated special bearing designs, which
improve performance and life in applications such as aerospace and defence, F1 motorsport, medical and surgical equipment, dentistry, machine tools, flight navigation systems and turbomolecular pumps. In these areas, the focus of Barden’s design process for bearings is the close integration of new materials, surface engineering, lubrication and sealing technologies. In materials technology, Barden’s engineers
select the most appropriate bearing materials to maximise bearing performance. Special ring materials are used successfully in aerospace and non-aerospace applications, combining superior corrosion and wear resistance with the ability to withstand higher dynamic loads than conventional bearing steels. When used in conjunction with ceramic balls, significant gains in bearing life and performance can be achieved. Barden has also taken the lead in surface
