2A001 Anti-friction bearings and bearing systems, as follows, and components therefor:

Note:

2A001 does not control balls with tolerances specified by the manufacturer in accordance with ISO 3290 as grade 5 or worse.

(a) Ball bearings and solid roller bearings having all tolerances specified by the manufacturer in accordance with ISO 492 Tolerance Class 4 (or ANSI/ABMA Std 20 Tolerance Class ABEC-7 or RBEC-7, or other national equivalents), or better, and having both rings and rolling elements (ISO 5593) made from monel or beryllium; (L.N. 132 of 2001; L.N. 65 of 2004)

Note:
2A001(a) does not control tapered roller bearings.

(b) Other ball bearings and solid roller bearings having all tolerances specified by the manufacturer in accordance with ISO 492 Tolerance Class 2 (or ANSI/ABMA Std 20 Tolerance Class ABEC-9 or RBEC-9, or other national equivalents), or better; (L.N. 132 of 2001; L.N. 65 of 2004)

Note:
2A001(b) does not control tapered roller bearings.

(c) Active magnetic bearing systems using any of the following:

(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 (177⁰C) and above) position sensors;
