I. Introduction:
The Life of Lubricating Greases in Ball Bearings Test Instrument is fully automatic controlled by a computer and automatically discriminates the results. After the sample is installed, the apparatus will automatically perform intermittent work according to the standard requirements, and the whole process does not need to be held manually, reducing the operation intensity. In order to avoid safety accidents, the new generation of products have fault reminders and automatic shutdown in case of instrument failure, so as to ensure the safe use of equipment or other hardware.
