Product Description

Product Description

Tapered roller bearing is a type of separable bearing with a conical structure on both the inner and outer rings. This type of bearing is divided into different structural types such as single row, double row, and four row according to the number of roller rows installed. Single row tapered roller bearings can withstand radial loads and axial loads in a single direction. When a bearing is subjected to radial load, an axial force component is generated, so another bearing is needed to withstand the axial force in the opposite direction to maintain balance.


The structure, assembly dimensional accuracy, and rotational accuracy of Inch size tapered roller bearings are different from those of metric bearings. Mostly used in industries with imported machinery or special needs.

Application

Tapered roller bearings are widely used in various fields, including the automotive industry, railway transportation, engineering machinery, wind power generation, mining equipment, aerospace, and metallurgical equipment.



Automotive industry: Conical roller bearings play an important role in the automotive industry, especially in the transmission, differential, wheel hub, and drive shaft, which can withstand high-speed rotation and large torque, while effectively reducing friction and wear and improving transmission efficiency.

Railway transportation: In the railway transportation industry, tapered roller bearings can withstand high-speed rotation and large radial loads, ensuring the safe operation of trains, and are also used in the transmission systems of railway locomotives and passenger cars.

Construction Machinery: In the construction machinery industry, such as excavators, bulldozers, and loaders, tapered roller bearings can withstand large radial and axial loads, while also having high rigidity and durability.

Wind power generation: In the wind power industry, tapered roller bearings are widely used in the main shaft, which can withstand the huge radial and axial forces generated by the rotation of fan blades.

Mining equipment: In mining equipment such as ore crushers and screening machines, tapered roller bearings can withstand large impact and vibration loads, while also having high reliability and durability.

Aerospace: In the aerospace field, tapered roller bearings are widely used in important parts such as aircraft engines, landing gear, and navigation equipment due to their special structural design and manufacturing process, which can meet the requirements of high-speed rotation and complex loads.

Metallurgical equipment: In metallurgical equipment such as rolling mills and continuous casting machines, tapered roller bearings can withstand large loads and impact loads, while also having high rotational speed and rigidity.
