There is a difference in the consistency (basic physical property value that expresses the hardness of grease).
There is no difference in lubrication performance and heat resistance.
No. 0 is softer than No. 2, and the consistency conforms to JIS standard.
No.0: Recommended for sliding parts of machines for locations where fretting (fine wear) is likely to occur, high-speed rotation and filling of lightweight locations.
No.2: For sealed ball bearings (bearing) It is recommended for heavy (torqued) places where a damper is required, places with strong surface pressure, and places where they are used for engagement.
