We explain how to select bearing grease based on base oil viscosity, NLGI class, thickener, speed, load, temperature, and relubrication interval.

We explain why greases with different thickener and base oil systems should not be mixed directly and how to manage product transitions.

We explain the differences between NLGI 00 and NLGI 000 semi-fluid greases and their usage criteria in central lubrication and enclosed gear applications.

We explain what NLGI 2 grease means, how its consistency class differs from the base oil viscosity, and the selection criteria for bearing applications.
