8483.90.20.00 - Parts of flange, take-up, cartridge and hanger units

This HTS category, 8483.90.20.00, specifically covers parts that constitute flange units, take-up units, cartridge units, and hanger units. These components are designed to support, align, and facilitate the rotation of shafts in various mechanical systems. Examples include the housings, mounting elements, and integrated bearing structures that form these specialized units, often utilized in machinery where precise shaft support and adjustability are critical.

While other parts related to bearing housings and plain shaft bearings fall under the broader heading of 8483.90, this subcategory is distinguished by its focus on pre-assembled or integrated units. It differentiates itself from the sibling category 8483.90.30.00, which encompasses "Other" parts of bearing housings and plain shaft bearings that do not fit the specific definitions of flange, take-up, cartridge, or hanger units. Therefore, classification here requires identifying the specific functional unit these parts contribute to.

As this is a leaf node within the HTS, there are no further subcategories. This means that any part fitting the description of a flange, take-up, cartridge, or hanger unit part, and not classifiable as "Other" under 8483.90.30.00, will be classified directly under 8483.90.20.00. The key is to recognize the integral nature of these parts as forming distinct functional units for shaft support.
