The lubrication majorly helps in separating mating surfaces to decrease friction, transferring heat and protecting the bearing from corrosion due to the dirt ingress.
To get these benefits, you will need to be certain that you follow the ideal lubrication procedure and apply the lubricant in the required quantity only.
Before continuing on to the lubrication procedure, you must first be educated about the types of lubricants available on the market. These include oil, grease and solid films.

Oil: Available in both oil and synthetic based oils, this lubricant is acceptable for bearings with greater speed capability. Their service life is lower than the grease because of evaporative losses. The significant elements to be considered when selecting oil are viscosity, evaporative speed, and temperature range.
Solid movies: In order to reduce the use of these machines, these non-fluid coatings are applied to the friction surfaces. Solid films function as the last choice when grease cannot do the job. Graphite, silver, gold, and PRFE are utilized as the coatings.
Grease: Baseoil is blended with a thickener like lithium, sodium, urea, calcium, and aluminum to generate grease. Attributes and lubricating properties of the grease is dependent on thickeners and base oil. Approximately 90 percent of the rolling bearings such as cylindrical roller bearings, tapered roller bearing etc. are lubricated with grease.
