Bearing Lubrication
One major contributing factor to a bearing's reliability is proper lubrication. Selecting the correct lubricant and maintaining it appropriately will significantly decrease the risk of premature bearing failure and running interference.
There are three main categories of bearing lubrication; oils, greases and solid dry film. Selection of the most appropriate lubricant is generally governed by the operating system and limitations of the bearing system.
- Selecting the right lubricant for a specific bearing and application can:
- Reduce friction and wear by supporting the load and separating the balls from the raceways.
- Minimise cage wear.
- Prevent oxidation/corrosion of the balls.
- Act as a barrier to contaminants.
- Conduct heat away from the bearing.
