Tapered Roller Bearings

Application Scenarios: In the automotive field, Brazil is one of the top ten automobile-producing countries in the world, with an automobile production of 2,369,600 units in 2022. Tapered roller bearings can withstand a large amount of axial and radial loads during the operation of automobiles, ensuring the stability and reliability of the automotive transmission system. In the mining field, Brazil is rich in mineral resources and has a strong demand for mining equipment such as ore crushers and roadheaders. Tapered roller bearings have high-speed rotation, good rigidity, low dynamic friction coefficient, and high durability, which can meet the working requirements of mining equipment.

Market Status: According to the report of XinSijie Industry Research Center, tapered roller bearings are widely used in the automotive, construction machinery, agricultural machinery, mining equipment and other fields in Brazil. Moreover, the supply of tapered roller bearings in the Brazilian market relies on overseas imports, and China is an important source of imports.

Ball Bearings

Deep Groove Ball Bearings: They are the most common type of ball bearings, consisting of an outer ring, an inner ring, rolling elements, and a cage. They are suitable for various mechanical devices and are widely used in the motor, automotive, general machinery and other fields in Brazil. They can withstand radial loads and a certain amount of axial loads and can adapt to high rotational speeds. For example, they are often used in the wheel hub bearings of automobiles and the rotor supports of motors.

Angular Contact Ball Bearings: They can withstand both radial and axial loads simultaneously, and have a relatively large axial load-bearing capacity. They are widely used in fields in Brazil where high requirements are placed on bearing accuracy and load-bearing capacity, such as machine tool spindles, high-speed motors, and aerospace. For instance, in some parts of aircraft engines, the bearings need to withstand large axial and radial forces during high-speed rotation, and angular contact ball bearings can meet this requirement.

Roller Bearings

Cylindrical Roller Bearings: They are suitable for high-speed and high-load occasions and are widely used in high-speed motors, machine tool spindles, industrial transmission equipment and other fields in Brazil. They can withstand large radial loads. The line contact between the rollers and the raceway results in a high load-bearing capacity. For example, large industrial motors need to transmit a large amount of power, and their bearings often use cylindrical roller bearings to withstand large radial forces.

Spherical Roller Bearings: They have good self-aligning performance and can automatically compensate for shaft bending and misalignment errors. They are widely used in large equipment such as mining machinery, metallurgical equipment, and paper-making machinery in Brazil. The shafts of these equipment are prone to bending and offset during operation, and spherical roller bearings can ensure the stable operation of the equipment and reduce bearing damage and equipment failures caused by shaft offset.

Plain Bearings

Self-lubricating Plain Bearings: They have self-lubricating properties and do not require an additional lubrication system. They can operate in an oil-free or low-oil environment. They are widely used in some special occasions in Brazil, such as food processing machinery, textile machinery and other equipment with high cleanliness requirements, as well as some equipment that is difficult to maintain lubrication. They can avoid product or environmental pollution caused by lubricating oil and reduce maintenance costs.

Oil-impregnated Plain Bearings: They contain lubricating oil inside. During operation, the lubricating oil will seep out to the bearing surface to form a lubricating film. They are commonly used in small motors, office equipment, household appliances and other fields in Brazil. They have the advantages of low cost, low noise, and convenient installation. For example, the bearings in small fan motors can meet their working requirements under low-speed and light-load conditions with oil-impregnated plain bearings, and the production cost and noise are reduced.
