Bearing housings, not incorporating ball or roller bearings and plain shaft bearings

HS v2017 Code: 848330

About bearing housings, not incorporating ball or roller bearings and plain shaft bearings

hs code 848330 covers a critical component in a wide range of industrial machinery and equipment. Bearing housings, also known as pillow blocks, are essential for supporting and protecting the bearings that enable the smooth and efficient operation of rotating shafts. This industry plays a vital role in the broader manufacturing and engineering sectors, ensuring the reliable performance of machinery across diverse applications such as automotive, aerospace, and industrial automation.

Production process

The production of bearing housings typically involves a combination of casting, machining, and assembly processes. Manufacturers often start with a metal casting, such as cast iron or steel, which is then machined to precise dimensions and tolerances. This includes boring the housing to accommodate the bearing, as well as adding features like mounting surfaces and lubrication ports. The final assembly may involve the integration of additional components, such as seals and locking mechanisms, to ensure the housing's durability and functionality.

Production inputs

The key inputs for the production of bearing housings include raw materials such as cast iron, steel, and various alloys. Specialized machinery, such as lathes, milling machines, and precision grinding equipment, are essential for the machining and finishing processes. Additionally, manufacturers may require various fasteners, seals, and lubricants to complete the assembly of the final product.

Production outputs

The primary output of hs code 848330 is the bearing housing itself, which is then consumed by a wide range of industries that require rotating machinery. These include 842111 Turbines, 842123 Compressors, 843149 Construction machinery, and 848210 Ball or roller bearings. The bearing housings produced under this code are crucial components that enable the smooth and reliable operation of these diverse industrial applications.
