What Are Babbitt Bearings
Babbitt bearings, also known as white metal bearings, are sliding bearings that use Babbitt alloy as the main surface material. Named after Isaac Babbitt, who first patented the material in 1839, Babbitt is a soft alloy usually composed of tin, antimony and copper for bearing surfaces. Although variations exist in which lead is used instead of tin in some applications. This composition may vary depending on the specific application, which is why some bearings contain lead instead of tin. The primary function of babbitt bearings is to provide a smooth, wear-resistant surface that reduces friction between moving parts, making them an indispensable component in many types of machinery.
Babbitt is softer than the shaft material and can embed small particles such as dirt, preventing them from causing severe wear on the shaft. Additionally, it adapts to shaft surface irregularities, ensuring more even weight distribution and reducing stress points. This feature is particularly useful in applications where shaft misalignment is possible.
Characteristics And Applications Of Babbitt Bearings
Babbitt bearings have a variety of different properties. After pasteurization hardening, they have high strength and excellent wear resistance, and perform well under high-speed, high-temperature and high-load working conditions.
Excellent corrosion resistance
Babbitt has extremely high corrosion resistance and is almost not corroded by corrosive media such as acids, alkalis, and salts. This allows Babbitt bearings to be used for a long time in corrosive environments such as chemical industry, petrochemical industry, and marine engineering, greatly extending the service life of the bearings and reducing maintenance costs.
Excellent high temperature performance
Babbitt has good high-temperature strength and thermal stability, and its performance remains stable in high-temperature environments below 500°C. This makes Babbitt bearings very suitable for use in high-temperature fields, such as aerospace engines, gas turbines, steel smelting and other industries.
Excellent mechanical strength
Babbitt has excellent tensile strength, compressive strength and high hardness, and can withstand heavy loads and severe impacts, thus ensuring that the bearings have good load capacity and reliability.
Self-lubricating properties
Babbitt itself has certain self-lubricating properties, which can reduce the friction coefficient and wear rate during bearing operation, extend the service life of the bearing, and reduce the maintenance workload.
Abrasion resistance and abrasion resistance
Babbitt bearings have excellent wear and tear resistance and can maintain a low wear rate even in harsh environments lacking sufficient lubrication, ensuring long-term and efficient operation of equipment.
Non-magnetic
Babbitt is a non-magnetic material, so Babbitt alloy bearings will not be affected by magnetic fields and can be widely used in various strong magnetic field environments, such as magnetic resonance imaging equipment, particle accelerators, etc.
These excellent properties of Babbitt bearings make them an ideal special bearing choice and are widely used in chemical industry, aerospace, oil and gas, electric power, metallurgy and other fields. In some harsh environments, such as corrosive media, high temperatures, strong magnetic fields, etc., Babbitt bearings are often the best solution to ensure long-term stable operation of equipment.
Widely used in many fields including：
Chemical and petrochemical industry: Babbitt alloy has excellent corrosion resistance and can effectively resist the erosion of some corrosive media.
Therefore, Babbitt bearings have been widely used in chemical pumps, valves, compressors and other equipment.
In addition, chemical processes are often accompanied by high temperatures, and the high-temperature stability of babbitt also makes it the preferred special bearing material in the chemical industry.
Aerospace field：Aviation equipment such as aero engines and gas turbines usually work in extreme environments of high temperature and high speed, and have strict requirements on the high temperature resistance of bearings.
Babbitt bearings have excellent high-temperature strength and thermal stability, making them an ideal choice for aerospace engines and gas turbines. In addition, when aerospace vehicles encounter radiation and other harsh environments in space, the wear resistance and corrosion resistance of babbitt bearings also play an important role.
Marine engineering field: Marine engineering equipment such as submersible platforms and offshore drilling platforms have been exposed to high-salt and high-humidity marine environments for a long time, which is a major test for the corrosion resistance of metal materials.
Babbitt bearings will not be corroded by seawater and other corrosive media, making them ideal for use on these devices.
Metallurgy and glass manufacturing fields: Metallurgy and glass manufacturing processes are often accompanied by high temperatures and corrosive gases, such as sulfide, fluoride, etc.;
Babbitt bearings can maintain excellent heat resistance and corrosion resistance in this environment, ensuring reliable operation of equipment.
Therefore, Babbitt bearings are widely used in equipment such as rolling mills in the metallurgical industry and wire drawing machines in the glass industry.
Food processing and pharmaceutical fields：The food processing and pharmaceutical industries have very strict hygiene and cleaning requirements for equipment.
The surface of Babbitt is smooth and non-porous, does not retain contaminants, can withstand high-temperature sterilization and strong oxidant cleaning, and meets hygienic standards.
At the same time, Babbitt also has good corrosion resistance and can resist acid and alkali corrosion of food and medicine.
Therefore, Babbitt bearings are also widely used in centrifuges, transfer pumps and other equipment in these industries.
Medical equipment field：The working environment of medical equipment such as magnetic resonance imaging equipment and proton therapy equipment is often accompanied by strong magnetic fields.
Babbitt is a non-magnetic material and will not be affected by magnetic fields. At the same time, its excellent corrosion resistance can also meet the clean and hygienic requirements of medical equipment.
