Maintenance and lubrication,you know?
Many bearings require periodic maintenance to prevent premature failure, although some such as fluid or magnetic bearings may require little maintenance.Most bearings in high cycle operations need periodic lubrication and cleaning,and may require adjustment to minimise the effects of wear.Bearing life is often much better when the bearing is kept clean and well-lubricated. However, many applications make good maintenance difficult. For example bearings
in the conveyor of a rock crusher are exposed continually to hard abrasive particles. Cleaning is of little use becausecleaningis expensive, yet the bearing is contaminated again as soon as the conveyor resumes operation.Thus, a goodmaintenance program might lubricate the bearings frequently but never clean them.
Service lifeRoller Bearings is determined by load, temperature, maintenance, lubrication, material defects, contamination, handling, installation and other factors. These factors can all have a significant effect on bearing life. For example, the service life of bearings in one application was extended dramatically by changing how the bearings were stored before installation and use, as vibrations during storage caused lubricant failure even when the only load on the bearing was its own weight; the resulting damage is often false brinelling. Plain bearings:For plain bearings some materials give much longer life than others.Flexure bearings rely on elastic properties of material.Flexure bearings bend a piece of material repeatedly. Some materials fail after repeated bending, even at low loads, but careful material selection and bearing design can make flexure bearing life indefinite.ExternalfactorsThe service life of the bearing is affected by many parameters that are not controlled by the bearing manufactures. For example, bearing mounting, temperature, exposure to external environment, lubricant cleanliness and electrical currents through bearings etc.
