Structure and principle
• Bimetallic structure: Oil-containing bimetallic bearings are usually composed of two different metal materials, such as carbon steel as the base material, which provides high strength and good load-bearing capacity, and copper alloy or other alloy materials as the surface layer to improve friction performance and lubrication effect.
• Oil-containing characteristics: Oil-containing bearings manufactured by powder metallurgy are porous, and these pores can be impregnated with lubricating oil. During operation, the lubricating oil will gradually seep out of the pores to form an oil film, thereby achieving self-lubrication and reducing direct contact and friction between metals.
• Self-lubricating mechanism: In addition to the oil-containing characteristics, oil-containing bimetallic bearings can also be inlaid with solid lubricants such as graphite, molybdenum disulfide, etc. on the surface. These solid lubricants will gradually release during operation, further reducing friction and wear.
Key advantages in solving the lubrication problem of heavy equipment
• High load capacity and impact resistance: The bimetallic structure enables the bearing to withstand higher loads and impact forces, which is particularly suitable for heavy loads, low speeds, reciprocating or swinging conditions commonly found in heavy equipment, effectively avoiding bearing damage caused by excessive loads.
• Excellent self-lubricating performance: The dual effects of oil-containing properties and solid lubricants enable the bearing to maintain good lubrication effects even when there is a lack of external lubricants or it is difficult to form an oil film, reducing wear and failure caused by insufficient lubrication and reducing maintenance costs.
• High temperature and corrosion resistance: The material and structure of the oil-containing bimetallic bearing enable it to adapt to harsh working environments such as high temperature, high pressure, and chemical corrosion. For example, in some industrial equipment, it can maintain stable operation even in the presence of corrosive media such as acid and water flushing.
• Long life and low maintenance: Due to its self-lubricating properties and good wear resistance, the oil-containing bimetallic bearing has a long service life and reduces the frequency of replacement. At the same time, it has strong adaptability to lubrication conditions, reduces dependence on the lubrication system, and reduces the workload of daily maintenance.
• Strong adaptability: By adjusting the base material, alloy composition and lubricant type, oil-containing bimetallic bearings can meet the requirements of different bearing pressures, temperature ranges and sliding speeds. They have strong versatility and adaptability and can be widely used in various heavy equipment.
Application fields
Oil-containing bimetallic bearings are widely used in the following heavy equipment fields:
• Engineering machinery: such as hydraulic systems, slewing bearings, walking mechanisms and other parts of equipment such as excavators, cranes, loaders, etc. These equipment usually work in heavy loads, low speeds, and large impact environments. Oil-containing bimetallic bearings can effectively improve the reliability and service life of the equipment.
• Mining machinery: In mining machinery such as crushers, mills, and screening equipment, bearings need to withstand high loads and harsh dust environments. The self-lubricating properties and wear resistance of oil-containing bimetallic bearings make them an ideal choice.
• Metallurgical equipment: such as the transmission system and supporting components of metallurgical equipment such as rolling mills and continuous casting machines. These equipment have high requirements for high temperature performance and corrosion resistance of bearings, and oil-containing bimetallic bearings can meet their needs.
• Automobile industry: used in the main bearings, connecting rod bushings, rocker bushings and other parts of automobile engines, as well as the balance bridge bushings of automobile chassis, etc., to improve the performance and reliability of automobiles.
• Industrial equipment: In industrial equipment such as textile machinery, injection molding machines, and papermaking machines, bearings need to withstand high loads and wear. Oil-containing bimetallic bearings can reduce equipment failure rates and improve production efficiency.
Oil-containing bimetallic bearings have played an important role in solving the lubrication problem of heavy equipment with their unique structural and performance advantages. It not only improves the operating reliability and service life of the equipment, but also reduces maintenance costs and work intensity, providing a strong guarantee for the efficient operation of heavy equipment.
