HS v2022 Code: 848330

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

HS code 848330 covers bearing housings, a critical component in a wide range of industrial machinery and equipment. These housings provide a sturdy and reliable enclosure for the bearings that support rotating shafts, enabling smooth and efficient operation. As a fundamental part of many mechanical systems, the bearing housing industry plays a vital role in supporting the broader manufacturing and production sectors across the global economy.

Production process

Bearing housings are typically produced through a combination of casting, machining, and assembly processes. The initial step often involves casting the housing body, either from metal alloys or high-performance engineering plastics, to create the desired shape and structural integrity. The cast components are then precisely machined to ensure accurate dimensions and smooth surfaces, often using computer-controlled equipment. Finally, the housing is assembled with any necessary seals, fasteners, and other accessories to create the complete bearing housing unit.

Production inputs

The main inputs required for the production of bearing housings include raw materials such as metals (e.g., steel, aluminum, cast iron) or engineering plastics, as well as specialized machinery and tools for the casting, machining, and assembly processes. Additionally, the industry relies on a range of components, including bearings, seals, and fasteners, which are often sourced from 848310 Ball or roller bearings and 732619 Other articles of iron or steel.

Production outputs

The primary output of the bearing housing industry is, of course, the bearing housings themselves, which are then incorporated into a wide range of industrial machinery and equipment. These housings may be used in applications such as 842112 Centrifugal pumps, 842123 Reciprocating positive displacement pumps, 842131 Rotary positive displacement pumps, and 843149 Other lifting, handling, loading or unloading machinery.
