The species, composition and characteristics of rolling bearing grease

Lubricating oil ( Fat) Is the blood of equipment, correct selection and use is very important to extend the service life of equipment. A, the composition is by lubricating oil (grease grease Base oil) , thickener, Thickener) Or soap base, additives ( Some species contain no additives) Mixture at high temperature. 1. 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 mixed in use) , 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 or soap thickener, also known as thickening agent, it is the adsorption of lubricating oil additives and/or material. 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 solids, clay, polyurea and silica gel as the foundation. 3. Additives, additives are used to provide additional features, such as wear-resistant and anti-corrosion protection to reduce the effect of friction, and under the condition of boundary and mixed lubrication to prevent damage, etc. The classification of the grease and there are many methods of classification of brand grease, but the general is according to the composition of the raw material of thickener, known as 'x x fat', such as sodium based grease, lithium base grease, etc. The commonly used types and can adapt to the working temperature of each table, in addition, according to the adaptation of the highest and lowest temperature, also can be divided into ordinary high temperature lubricating grease and three types of low temperature grease; According to the adaptation of the highest speed, but also can be divided into two categories, ordinary and high speed grease grease.
