  • 7. Lubrication of Bearings - NTN

    Bearing Lubrication The most important task of the lubricant is to separate parts moving relative to one another (balls or rollers and raceways) in order to minimize friction and prevent wear. A lubricant that is designed for specific operating conditions will provide a load bearing wear protective film.

  • Ball Bearings vs Roller Bearings: How Are They

    2020-2-27 · While a ball bearing can handle a misalignment of up to 0.004 inches, a cylindrical roller bearing might already have difficulty rotating when misaligned by anything more than 0.001 inches. This means that roller bearings need to be designed at a much higher level of precision, making them more difficult and expensive to manufacture.
