1.Different shapes: 

   Grease is gelatinous, butter is paste, they are different in essence.

   2. Different uses:

   Lubricating grease is generally used outside the mechanical equipment. The application of this kind of grease makes the mechanical equipment more self-sufficient in the process of operation, plays an ideal smooth effect. It also can effectively clear some debris dregs that may occur in the process of movement, adhere to the cleanness of the mechanical equipment.

   Butter is used to set fire withstand pressure, which plays a certain role in maintaining the rolling bearing, so that the bearing will be deformed due to low temperature. The use of butter is relatively rare. It may be used to repair bicycles, because when repairing bicycles, especially bearings, the butter is used. The function of butter is put in bearings, then steel balls are put in, which can drive bearings.3.效果不同：
         The effect of grease is aimed at the mechanical equipment, which plays a very ideal role in smoothing cleaning the equipment, while butter is used to smooth stabilize the beads, the effect in industry is as good as grease. So the difference between the two is here.

  Grease is also known as medium oil butter, so in fact, the two are a concept. Moreover, it is a thick grease like semi-solid, which is generally used for the friction part of machinery, so as to play a smooth sealing role, sometimes it can also be used for the metal surface, playing the role of filling the gap rust prevention.       

  This kind of grease is mainly made of mineral oil thickener. In addition, this grease can be divided into saponified grease non saponified grease according to different thickeners, general grease public grease can be known according to the way of application. The former is used for common mechanical parts, while the latter is used in industries such as tractors railway locomotives.
