Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If thrust-optimized linear bearings for vertical applications
Bearings primarily designed for axial thrust loads may fall under different statistical suffixes.
If with integrated non-contact linear scale
Bearings incorporating precision measurement capabilities classify as position measuring instruments.
If rails imported separately from carriage blocks
Profile rails without rolling elements are parts of bearings under 8483.90 toothed wheels and other transmission parts.

Import Tips & Compliance
• Specify block size (width x length x height) and preload class in commercial invoices for accurate duty assessment
• Include material certificates confirming bearing steel (e.g
• SUJ2) construction
• For cleanroom versions, document low-particle grease to support semiconductor end-use claims
