Powder Metal Bearings
Powder metal bearings are made by pressing, sintering, shaping, and immersing metal powders and other anti friction material powders in oil. They have a porous structure, and after being immersed in hot oil, the pores are filled with lubricating oil. During operation, due to the suction effect and frictional heating caused by the rotation of the journal, the metal and oil are heated and expanded, pushing the oil out of the pores and lubricating the friction surface. After the bearing cools down, the oil is sucked back into the pores. Powder metal bearings do not require the addition of lubricating oil for a long period of time. The higher the porosity of powder metal bearings, the more oil they can store, but the more pores they have, the lower their strength. These types of bearings are often in a mixed lubrication state and can sometimes form thin film lubrication. They are commonly used in situations where it is difficult to replenish lubricating oil, light loads, and low speeds.
- Product Introduction
Powder metallurgy oil containing bearings (oil containing bearings) are a type of porous alloy product with lubricating oil impregnated in the pores. When the shaft rotates, the friction between the shaft and the oil bearing causes the temperature of the oil bearing to rise and the pumping effect to occur. Lubricating oil infiltrates from the friction surface of the inner or outer diameter of the oil containing bearing when the shaft stops rotating. The lubricating oil flows back into the oil containing bearing. Therefore, the consumption of lubricating oil is very small and can be used for long-term operation without external supply of lubricating oil. Very suitable for situations where oil supply is difficult and lubricating oil pollution is avoided.
