ECCN 2A001
NSMTATAnti-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.
Items Covered
- a.Ball bearings and solid roller bearings, having all tolerances specified by the manufacturer in accordance with ISO 492 Tolerance Class 2 or Class 4 (or national equivalents), or better, and having both 'rings' and 'rolling elements', made from monel or beryllium;
- c.Active magnetic bearing systems using any of the following, and specially designed components therefor:
- 1. Materials with flux densities of 2.0 T or greater and yield strengths greater than 414 MPa;
- 2. All-electromagnetic 3D homopolar bias designs for actuators; or
- 3. High temperature (450 K (177 °C) and above) position sensors.
