HS v2017 Code: 841221

About engines; hydraulic power engines and motors, linear acting (cylinders)

hs code 841221 covers hydraulic power engines and motors, linear acting (cylinders). These specialized engines play a crucial role in a wide range of industrial applications, from construction equipment and manufacturing machinery to agricultural vehicles and marine systems. As a key component in the broader hydraulic power industry, this code represents a significant segment of the global economy, enabling the efficient conversion of hydraulic energy into mechanical power.

Production process

The production of hydraulic power engines and motors, linear acting (cylinders) typically involves a multi-step manufacturing process. This often begins with the fabrication of the cylinder housing, which is designed to withstand the high pressures and forces generated by the hydraulic fluid. The piston and associated components, such as seals and bearings, are then precision-engineered to ensure smooth and efficient linear motion. Finally, the entire assembly is carefully tested and calibrated to meet the specific performance requirements of the intended application.

Production inputs

The production of hs code 841221 items requires a range of specialized inputs, including high-strength metals, such as steel and aluminum, for the cylinder housing and other structural components. Advanced materials, such as engineered plastics and composites, may also be used to optimize weight and durability. Additionally, the manufacturing process relies on specialized machinery, including CNC machining tools, welding equipment, and precision assembly stations. Hydraulic fluid, seals, and other ancillary components are also essential inputs for the final product.
