Bearings With Oil, that is, porous bearing, metal powder as the main raw material, oil bearing is made of powder metallurgy sintered body, which is originally porous, and has the technical advantages of the manufacturing process can be more free to adjust the number, size, shape and distribution of pores
It has the characteristics of low cost, can absorb vibration, low noise, no need to add lubricating oil in a long working time, etc. It is especially suitable for the working environment which is not easy to lubricate or does not allow oil to be dirty.
Using the porous characteristics of the material or the affinity characteristics with the lubricating oil, the shaft tile material is soaked in the lubricating oil before it is installed and used, so that INA bearing factory reminds you that the bearing can work without adding or long time without Bearings with oil.
When the eccentricity of the oil bearing is larger, the corresponding bearing load capacity will also increase, while the friction coefficient of the bearing will also be reduced. However, the eccentricity of oil bearing value change is relatively passive, in the use of the time and will not change independently, so the use of the process of bearing load, the bearing eccentricity will also increase, while the bearing bearing capacity increases.
When the Bearings with oil is in a non-running state, the lubricating oil fills the pores, and when it is running, the shaft rotates and heats up because of friction, and the thermal expansion of the shaft tile reduces the pores, so the lubricating oil will overflow into the gap of the bearing. When the shaft stops running, the shaft tile is cooled, the pore space is restored, and the lubricant returns to the pore space. Therefore, the consumption of lubricating oil is quite small, and it is possible to maintain the operation without external lubricating oil supply. This type of bearing is especially suitable for applications where oil supply is difficult or where lubricating oil pollution must be avoided.
Bearing material is mainly porous material, after impregnated with lubricating oil, the pores in the material will be filled with lubricating oil. Common materials include powder metallurgy, cast iron, cast copper alloy, wood and some other materials.
The main material of bearing is plastic, this kind of plastic has affinity with lubricating oil and can be soluble, after certain process, the lubricating oil is evenly dispersed in the material, this kind of material commonly has oil-containing phenolic resin.
Bearings with oil are widely used in the manufacture of electric motors, household appliances, digital products, office equipment, power tools, textile machinery, packaging machinery and automobiles and motorcycles. Among the oil-containing bearings, the most widely used should be powder metallurgy Bearings with oil.
