8483.30.40.40 - Ball or roller bearing type

HTS Code 8483.30.40.40 specifically classifies "Ball or roller bearing type" bearing housings, housed bearings, and plain shaft bearings that are designed in a flange, take-up, cartridge, or hanger configuration. These units integrate bearings within a housing that is intended for specific mounting arrangements, such as bolting to a surface (flange and cartridge types), supporting a shaft from above (hanger type), or allowing for axial adjustment (take-up type). The defining characteristic for this subcategory is the incorporation of ball or roller bearing elements within these specialized housing structures.

This classification is distinct from its sibling category, 8483.30.40.80, which covers "Other" bearing housings, housed bearings, and plain shaft bearings not fitting the specific flange, take-up, cartridge, or hanger configurations. Essentially, if the bearing housing or unit does not possess one of these pre-defined mounting or adjustment features and instead represents a more general or custom design, it would fall under the "Other" designation.

As a leaf node, 8483.30.40.40 has no further subcategories. Therefore, the focus for classification within this code is on accurately identifying units that incorporate ball or roller bearings and are manufactured with the distinct physical attributes of a flange, take-up, cartridge, or hanger unit. Practical considerations for classification include examining the shape, mounting holes, and any mechanisms for adjustment present on the bearing housing.
