How to choose bearings lubricant

(1) Choose NSK bearings lubricant
a. Solid lubricant: mainly suitable for NSK deep groove ball bearings with a temperature> 200℃.
b. Grease: Applicable to all NSK bearing types, select according to thrust and grease type, except for thrust spherical roller bearings. It is characterized by low friction and low noise.
C. Lubricant (large dose): suitable for all NSK bearings. The viscosity of lubricating oil determines its noise reduction effect and good heat dissipation effect. The circulating movement of the lubricating oil and the lubrication between the lubricating oil and the steel can expel friction particles from the motion system, but the vortex formed by a large amount of lubricating oil will cause friction, resulting in energy loss.
d. Lubricant (small dose): suitable for all NSK bearings. The viscosity of lubricating oil determines its noise reduction effect, and the amount and viscosity of lubricating oil determine the size of friction.
(2) Selection of NSK bearing lubricant
The following points should be considered when selecting NSK bearings lubricants:
a. Working environment;
b. Operation, noise, friction and temperature requirements;
c. Safety requirements for friction, fatigue, corrosion and damage caused by foreign matter (water, sand, etc.) that penetrated from the outside in the previous accident;
d. Installation and maintenance costs;
e. 70%-80% of the bearings are lubricated with grease.
