Lubriion of linear bearings: Choosing between grease

Aug 01, 2015· Lack of bearing lubriion is generally regarded as the nuer one cause of linear-bearing failure. For recirculating linear bearings such as profiled rail guides and ball screws, lubriion separates the bearings (ball or roller) from the raceways, minimizes friction and wear, dissipates heat, and prevents corrosion.
