Transmission shafts (including cam shafts and crank shafts) and cranks

HS v2022 Code: 848310

About transmission shafts (including cam shafts and crank shafts) and cranks

HS code 848310 covers the production and trade of transmission shafts, including camshafts and crankshafts, as well as cranks. These components are essential parts of various mechanical systems, particularly in the automotive and industrial machinery industries. They play a crucial role in the efficient transmission of power and the smooth operation of engines and other machinery, making them a vital element in the broader manufacturing and transportation sectors.

Production process

The production of transmission shafts and cranks typically involves a combination of forging, machining, and heat treatment processes. Manufacturers start with raw materials, such as steel or alloy bars, which are then shaped and refined through a series of steps, including cutting, turning, milling, and grinding, to achieve the desired specifications and tolerances. Heat treatment processes, such as quenching and tempering, are often employed to enhance the strength, durability, and reliability of these components.

Production inputs

The main inputs required for the production of transmission shafts and cranks include high-quality steel or alloy materials, specialized metalworking machinery (e.g., lathes, milling machines, and grinding equipment), and various tools and consumables (e.g., cutting tools, lubricants, and coolants). Additionally, the industry relies on skilled labor, engineering expertise, and quality control measures to ensure the production of reliable and high-performance components.

Production outputs

The primary outputs of HS code 848310 are transmission shafts, camshafts, crankshafts, and cranks, which are then consumed by various industries, including 870000 Motor vehicles, trailers and semi-trailers, 842100 Machinery for the preparation of meat or poultry, and 848410 Gaskets and similar joints of metal sheeting combined with other material or of two or more layers of metal. These components are essential for the proper functioning of engines, transmissions, and other mechanical systems, making them a crucial part of the broader manufacturing and transportation supply chains.
