ECCN 2A001

NSMTAT

Anti-friction bearings, bearing systems and components, as follows, .

What This ECCN Covers

ECCN 2A001 controls precision anti-friction bearings, bearing systems, and components — including ball and solid roller bearings made to ISO 492 Tolerance Class 2 or 4 (or national equivalents) and active magnetic bearing systems with specified materials and capabilities. Tight-tolerance bearings are controlled because they are essential to high-speed rotating machinery such as missile guidance hardware and gas centrifuges. Control reasons are National Security, Missile Technology, and Anti-Terrorism.

Who needs to check this?

Bearing manufacturers, precision-machinery suppliers, and exporters of aerospace, turbomachinery, or motion-control components.

Compliance tip

Because 2A001 carries Missile Technology (MT) controls, license exceptions are generally unavailable and a license is typically required regardless of destination — do not assume LVS or GBS applies. Confirm the tolerance class of your bearing; commercial-grade bearings looser than Class 4 are usually not controlled under this entry.
