1. Automobile industry:
Spherical roller bearings play a vital role in the automotive industry. They are commonly used in parts such as engines, transmission systems, suspension systems and wheel bearings. In engines, spherical roller bearings support the rotation of the crankshaft and camshaft, as well as various components of the valvetrain. In drivetrains, they are used to support the input and output shafts of the gearbox. In suspension systems, spherical roller bearings allow free movement of suspension elements in different directions to provide a comfortable ride and stability of the suspension system. Most importantly, among wheel bearings, spherical roller bearings bear the weight of the entire vehicle and the vibration and shock in various road conditions.
For example, a typical application of wheel bearings is on the front and rear axles of automobiles. They need to withstand shock and vibration from road irregularities while ensuring free rotation of the wheels. This requires bearings that can maintain low friction when rotating at high speeds while having a high degree of wear resistance and load-bearing capacity. Spherical roller bearings excel in this regard, so they are widely used in the automotive industry to ensure vehicle performance and safety.
2.Heavy machinery:
The heavy machinery industry includes construction equipment, mining machinery, agricultural machinery, and port handling equipment, among others. These devices often face high loads, high vibrations and harsh working environments. Spherical roller bearings play a key role in these applications due to their high load-bearing capacity and vibration-absorbing properties. For example, in construction equipment such as excavators and loaders, spherical roller bearings are used to support bucket wheels, hydraulic arms and buckets to withstand the impact and high vibrations of heavy materials. Not only do these bearings have to withstand huge loads, they also need to maintain reliability under operating conditions.
Another example is the mining industry, where spherical roller bearings are widely used in ore crushers, conveyors and screening equipment. These equipment need to operate for long periods of time, so the durability and low maintenance requirements of spherical roller bearings are critical to reducing production downtime.
3. Railway transportation:
Railway transportation is a field that requires a high degree of reliability and safety. In railway vehicles, trains and railway track systems, spherical roller bearings are used to support the weight of the train, the rotation of the axles and the suspension system of the railway vehicle. These bearings must maintain reliability under long-term high load and high-speed operating conditions while having good impact resistance and vibration absorption properties.
For example, train wheel bearings are usually spherical roller bearings, and they need to withstand the overall weight of the train, as well as the changing curves and vibrations of the rails. These bearings must have long life and high reliability to ensure safe and efficient operation of railway traffic.
4.Aerospace industry:
In the aerospace industry, spherical roller bearings are used to support a variety of moving parts, including aircraft engines, flight control systems, landing gear and flight surfaces. These bearings must be able to operate under conditions, including high temperatures, high speeds and high pressures.
For example, an aircraft's main landing gear is often equipped with spherical roller bearings to support the aircraft's weight and absorb shock during landing. These bearings also need to operate in a variety of weather conditions, so their sealing and corrosion resistance are also key factors.
5. Energy industry:
The energy industry includes power plants, wind turbines, hydroelectric plants and oil drilling equipment, among others. In these applications, spherical roller bearings are used to support various rotating components in generators, wind turbine rotors, hydro turbines and oil drilling equipment.
For example, main shaft bearings in wind turbines often use spherical roller bearings to support the rotation of the wind turbine's huge blades and wind rotor. These bearings are required to withstand the high-speed rotation of wind turbines in harsh weather conditions, so their durability and performance are critical.
6. Paper and printing industry:
In the paper and printing industries, spherical roller bearings are used to support high-speed cylinders, rollers and various rotating parts of printing machinery. These bearings need to have low friction, high wear resistance and high reliability.
For example, bearings in printing machinery are used to support the rotation of printing cylinders to transfer ink to the printing media. These bearings must operate at high speeds while maintaining print quality and accuracy.
7. Steel industry:
Equipment in the steel industry often has to deal with high temperatures and high load conditions, so spherical roller bearings play a key role in this area. They are used to support various rotating parts of rolling mills, continuous casters and steelmaking equipment in the steel production process.
For example, bearings in rolling mills are used to support the rotation of rollers that turn billets into plates or steel products. These bearings need to withstand high temperatures and loads and need to remain reliable over long periods of operation.
8. Food and pharmaceutical industry:
The food and pharmaceutical industries require equipment with a high degree of hygiene, so bearings must be corrosion-resistant, easy to clean, and operate in environments with strict hygiene requirements.
For example, in food processing equipment, spherical roller bearings are used to support a variety of rotating components, such as mixers, conveyor belts and packaging machinery. These bearings need to be protected from food contamination and operate in high humidity and temperature conditions.
9. Chemical industry:
Chemical equipment often handles corrosive media and high temperature conditions. Spherical roller bearings are used to support various rotating parts in chemical equipment such as pumps, mixers and reactors.
For example, bearings in chemical pumps need to withstand the corrosive nature of chemicals while operating at high temperatures and pressures. This requires bearings to be corrosion-resistant and capable of maintaining reliability under operating conditions.
10.Ocean Engineering:
In marine engineering, equipment often needs to work in harsh environmental conditions such as seawater, salinity and waves. Spherical roller bearings are used to support and position various components of equipment such as offshore platforms, ships and submersibles.
For example, spherical roller bearings are often used in the lifting system of offshore platforms to support the rotation and lifting of the drill bit. These bearings need to be protected against seawater erosion and remain reliable in harsh marine conditions.
Spherical Sealed Spherical Roller Bearings Bearings ：20000 Series
Spherical roller bearings are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions.
Spherical roller bearings have two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis. The Centre point of the sphere in the outer ring raceway is at the bearing axis. Therefore, the bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, which can be caused.
