8482.10.50.12 - Linear bearings

This HTS category, 8482.10.50.12, specifically classifies linear bearings. Linear bearings are a type of rolling-element bearing that allows for linear motion. Unlike radial or thrust bearings, their primary function is to facilitate movement along a single axis, enabling smooth, low-friction translation. They are essential components in a wide range of industrial machinery and automation systems where precise linear movement is required.

Distinguishing this category from its siblings is crucial for accurate classification. While 8482.10.50.08 covers thrust bearings (designed for axial loads) and other unnamed angular contact and radial bearings (designed for combined or primarily radial loads), this category is solely for bearings engineered to support and guide motion in a straight line. The distinction lies fundamentally in the intended direction and nature of the movement the bearing facilitates.

As this HTS code represents a leaf node, there are no further subcategories within this specific classification. Therefore, the focus for classification under 8482.10.50.12 is on identifying bearings that fulfill the definition of linear motion and do not fit within the more specific sub-classifications of radial, thrust, or angular contact bearings. This typically involves bearings that utilize rolling elements (balls or rollers) to achieve linear displacement along a shaft or rail, often within a housing.
