Vibration Analysis - an overview | ScienceDirect Topics

Vibration affects the reliability of a structure or machine, causes damages or failures of the structure or machine. Vibration degrades the human comfort and induces the fatigue and health related problems. Vibration energy is usually dissipated through damping loss and lost in a form of waste heat energy.

Bearing | Article about bearing by The Free Dictionary

Ball bearings or roller bearings reduce friction more than sliding bearings do. Other advantages of antifriction bearings include ability to operate at high speeds and easy lubriion. A journal bearing usually consists of a split cylindrical shell of hard, strong metal held in a rigid support and an inner cylindrical part of soft metal, which holds a rotating shaft, or journal.
