Detailed Information on Types of Bearing Lubrication

Lubrication provides a thin film between the contact areas in a bearing to reduce friction, dissipate heat and inhibit corrosion on balls and raceways. The lubricant will affect maximum running speed and temperature, torque level, noise level and, ultimately, bearing life. There are a range of options depending on the application.

Bearing Lubrication Methods Bearing Tips

Sep 04, 2014Grease is normally applied with special lubricating equipment with a head that deposits the grease between the balls forcing it into, and around, the ball (or roller) raceway interface. Upon rotation the grease is distributed within the bearing, however, only the bearing should be completely filled with grease prior to start-up and the free

The Three Mistakes of Bearing Lubrication Applications

Mistake 1 Lubricating Is Based on Time Instead of ConditionMistake 2 Over and Under LubricationMistake 3 Using A “Listen-Only” Ultrasound InstrumentClear Benefits of Avoiding The Three MistakesLubricating a bearing once per week or once per month may seem like a sensible thing to do. After all, performing scheduled maintenance at regular periods is an age-old concept.Bearings need grease for one reason only, to reduce friction. As long as the lubricant is performing that service well, there should be no need to change it, or add more. Yet we frequently do, with catastrophic results.Lubricatin在maintworld上查看更多信息
