Bearing maintenance and inspection during operation

Things to observe:

Changes in:

Noise Vibrations Temperature Lubrication decolouring Leaking bearing seals

These changes are dependent on the lubrication conditions, including speed, loading, lubrication and environment. Detecting a change form the baseline condition will indicate possible deterioration of the bearing and suggest an immediate maintenance action.

Electronic stethoscope Can determinate noise level. Able to find parts with defects Sound meter. Instrument for measuring sound level in decibels [dB] Thermocouple. Instrument for measuring temperature. Thermocouple must be in contact with the bearing Infrared thermometer. Able to measure temperature from a distance. This permits temperature measurement from a distance without contact with the bearing to be measured. A non-contact infrared thermometer is useful for measuring temperature under circumstances where thermocouples or other probe-type sensors cannot be used or do not produce accurate data for a variety of reasons Thermal camera. Device which create an image with accurate temperature data, providing crucial information about condition of equipments. Can offer inspection of the equipments more safer than at peak operation. Endoscope. A miniature camera, with LED lightening, enveloped in a flexible tube, able to give images (directly on screen, or on a computer) from spaces hard to reach.
