NOISE TESTING AT HOFFMANN BEARINGS

METHODS of assessing the level at which vibration becomes unacceptable in any bearing are generally based on comparison. Hoffmann have now initiated a programme to substitute comparative measurements of bearing vibration with quantitative measurements. To be able to achieve this a means of accurately calibrating vibration transducers had to be devised and a start has been made on compiling and analysing data relating to acceptable vibration characteristics or rolling bearings in a wide range of service applications.
