Lubricants can reduce friction, it also avoids wear and tear and corrosion, prevent pollution of NSK bearing of solids and liquids.
In theory, a well lubricated, in ideal working conditions bearing life can be permanent, it is simply not possible, but if the correct lubrication of NSK bearings, bearing maximum life.
Between the sliding surfaces of the bearing forms a protective film, even in case of heavy loads, it can avoid the metal friction occurs. Rolling bearing lubrication grease lubrication is generally to existing or, in some special cases, NSK bearing used solid lubricants are good.
