a. Ball bearings and solid roller bearings, having all tolerances specified by the manufacturer in accordance with ISO 492 Tolerance Class 4 or Class 2 (or national equivalents), or better, and having both 'rings' and 'rolling elements', made from monel or beryllium;
Note 2.A.1.a. does not apply to tapered roller bearings.
Technical Notes
For the purposes of 2.A.1.a.:
1. 'Ring' is an annular part of a radial rolling bearing incorporating one or more raceways (ISO 5593:1997).
2. 'Rolling element' is a ball or roller which rolls between raceways (ISO 5593:1997).
b. Not used since 2010
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.
Note 2.A.1.a. does not apply to tapered roller bearings.
