INA bearing usually have the following basic requirements for lubricant

 (1) have sufficient lubricating effect, is able to reduce the friction of INA bearings and inhibit unwanted wear in the bearings, friction small, greater abrasion resistance capacity.
(2) prevent the occurrence of INA bearing corrosion, itself will not cause a INA bearing constituent parts (such as brass cage, rubber seals, etc) of corrosion, deterioration or deformation.
(3) in the context of provisions of the upper and lower temperatures, always maintain the necessary lubrication performance, stable chemical composition, viscosity change.
(4) within the required scope of the upper and lower limits of the working speed, are able to establish sufficient thickness of oil film; itself clean, does not contain impurities, good defoaming.
(5) within the required period or inventory period, physical properties and chemical properties of stable enough, does not affect the use of quality degradation.
(6) maintenance, maintenance to simple, ancillary installations as little as possible.
(7) in meeting the technical requirements of the above premise, to economise on the economy.
