Precision bearing manufacturer Schaeffler and the Friedrich-Alexander University Erlangen-Nürnberg (FAU) have developed a new rolling-bearing spin test stand as part of a collaborative research project designed to optimise current rolling-bearing technology with the aim of cutting fuel consumption in vehicles, as well as the energy used by machines.

To date, very little research has been conducted into the friction behaviour of rolling bearings subjected to the high centrifugal forces that can be generated by the rolling-bearing spin test stand.

Professor Sandro Wartzack, head of engineering design at the university, says: “This equipment comprises one of the largest projects we have ever undertaken; it is a perfect example of the excellent co-operation between industry and universities in the field of fundamental rolling-bearing research. The equipment will allow us to investigate which factors — such as temperature, coatings and geometric details — actually influence the bearings under extreme loads.”

Oliver Graf-Goller, Schaeffler’s bearings and components development project manager, said: “The results of the tests will allow us to refine our simulation tools for rolling bearings. Transferring the findings into application-oriented conditions will further improve our product development.”

The last round of tests and adjustments to the equipment is being carried out. Further information can be obtained from Schaeffler UK’s Communications and Marketing Department ().
