When machine vibration increases, one of the first questions to ask is: “Is a failing bearing causing the vibration?” In the case of rolling element bearings, it’s not difficult to separate vibration ...

Precision bearing manufacturer Schaeffler UK has extended its range of condition monitoring (CM) services for the UK market. With its unique combination of expertise in bearing failure analysis, ...

Magnetic bearings have probably amassed more hours of contemplation among engineers than they have actual hours of running time. Their ability to operate unlubed without wear has always been held back ...

After the ISA converges, the rotor vibration amplitude Vin is gradually reduced. in V drops from 11.74 um to 2.70 um, decreasing by 77.0%. Performing FFT analysis to the rotor displacement, the 1st ...

High vibration is a common problem for motors installed on top of vertical pumps. Its source can stem from a mechanical issue with the pump, motor, or coupling — or even hydraulic forces from the pump ...
