Lubricating oil (
Base oil)
Lubricating oil is used for lubrication of effective components, accounting for more than 70% of the total, known as the grease lubrication base oil, base oil for short.
Lubricating oil mainly from special mineral oil refinery, and vegetable oil and oil.
Synthetic oil with special application, for example, moderate ultra-high ultra-low temperature.
Different composition of lubricating oil, and some can be compatible with each other (
Can be used mixed together)
, others are not compatible with each other,
Can not be mixed together to use)
。
Not compatible with each other two kinds of lubricating oil are mixed together, may lose lubrication, and even cause severe damage to the bearing.
2.

Thickener formed from soap or soap base.
Its type determines the typical characteristics of the grease.
Barium soap base with lithium, calcium, sodium, or aluminum as the foundation;
The soap base with organic and inorganic parts, clay particles, polyurea and silica gel as the foundation.
3.
Additive additive due to provide additional features, such as wear-resistant and anti-corrosion protection, reduce the effect of friction, and under the condition of boundary and mixed lubrication to prevent damage, etc.
