How to Choose The Suitable Lubricant Grease ?

It’s hard to imagine a machine operating without grease in it, as the majority of dynamic machine operations run on bearings, which need grease for lubrication.But how to choose the suitable grease for our machine?

When choosing lubricating grease,  we need to considering the main conditions of friction (load, speed, temperature), working status (continuous operation, intermittent operation, vibration and impact, etc.) and working environment (humidity, temperature, air pollution level, etc.

1) The working temperature of lubricating grease should be at least 20-30 degrees lower than its droppoint point

When the machine request for high working temperature, you should choose grease with good antioxidant performance, less evaporation loss, and high dropping point; When the machine  working  under low temperature, you should choose a low -initiating moment and small viscosity base oil

2) The selected lubricating grease should be compatible with the use speed of being lubricated

At high speed, you must choose a  lubricating grease  made of a large cone in low viscosity base oil; for low -speed fat, you should choose the  lubricating grease  made of a high conical income brand made of high viscosity base oil.

3) The selected lubricating grease should be compatible with the load size.

When heavy load, you should choose a lubricating grease with high base oil viscosity and high thick agent content. When the load is particularly large, you should pay attention to the choice of lubricating fat with pole pressure additives or fillers (mesh -sulfide, graphite); when low -low load, generally use the lubricating grease with short consistency soap fiber structure and medium viscosity base oil.

4) The selected lubricating grease should be compatible with the environmental conditions used

In the environment of humid air or contact with water, you should choose lipids with good water resistance such as calcium, lithium, and composite lithium -based; for a long time, you should choose fat (that is, a higher card number) fat. Good, prevents impurities from mixed with friction.

In the environmental environment, a synthetic oil lubricating fats such as fluorocarbon grease should be selected.

5) The selected lubricating grease should be compatible with the method of friction and the sidelines When concentrated, you should choose 00 to 1 lubricating grease; for regular use of fat guns, fat cups and other parts, you should choose No. 1 to 3 lubricating grease; for long -term use without changing grease, you should should Select No. 2 or No. 3 lubricating grease.

6) The selected lubricating grease should be compatible with the working status of the friction vice

For example, when the vibration is large, grease with high viscosity, adhesion and vibration reduction, such as high viscosthane alkyl or mixed base lubricating composite soap base lubricating grease.

7) The selected lubricating grease should be adapted to the purpose of the use

Specific choices for the types, working conditions, working conditions, environmental conditions, and fat supply methods for lubricating grease for lubricating lubrication; for the protection of lipids used, it should effectively protect metal from corrosion, such as protecting protection, such as protection In contact with seawater water, aluminum -based lubricating fat with strong adhesion and high water resistance should be selected. Generally, lipids can be selected from lipids with lipid thickness of high viscosity base oil. For sealing grease, pay attention to its resistance to the sealing medium solvent.

8) Selected grease should be kept as much as possible to reduce the variety of fat and improve economic benefits.

In the case of satisfying the requirements, try to use lithium -based grease, composite soap -based grease, polycipotosol and other multi -effect -effective lubricating grease. In this way, it not only reduces the variety of lipids, simplifies the management of grease, and reduces the cost of lipids and reduce maintenance costs due to the long life of multi -efficiency grease.
