Learn About Vibration, Volume 1: Basic

Driven machinery bearings that are in harsh environments such as vertical shaft cooling towers, weather exposed, gaseous/moisture mix, or very dirty areas can become contaminated if not protected by special seals, cooling discs, or shaft assembly guards. Careful not to over grease motors. Motors should also be protected with silicone around bell faces and wire boxes if exposed to high moisture

How is Vibration Measured? Reliabilityweb: A

Vibration measurements are thus usually taken at the bearings of machines, with accelerometers mounted at or near the bearings. Since conclusions regarding machine condition and hence whether or not money and human safety are risked depend on the accuracy of measurements, we must be very careful how measurements are taken.
