Bearing Maintenance Practices To Ensure Maximum Bearing Life
MetadataShow full item record
Reliability of centrifugal pumps is heavily dependent on bearing reliability. The bearings that support the impeller shaft are complex machine components whose service life is directly affected by: Contamination (both particulate and water); Lubrication method and lubricant type; Mounting and dismounting techniques; Selection of components; Control of inactive bearing rolling elements; Proper housing support and alignment. In addition, there are major risks to bearings from unexpected loading conditions as well as exposure to vibration while idle. The effects of these conditions and how to avoid the risks need to be considered in order to maximize service life. Lastly, condition monitoring is an excellent way to maintain awareness of the health of bearings. However, even the best condition monitoring tools and techniques are of little value if not implemented and interpreted correctly.
