"""Deep groove ball bearing, single row, metric: miniature (6xx, MR), 60, 62, 63, 68 and 69 series, open, shielded
(ZZ) or sealed (2RS), optionally with a flange on the outer ring.

Envelope model for assemblies: one solid with the boundary dimensions (bore d, outside diameter D, width B) and, when
flanged, the flange (diameter D1, width C1) flush with the bottom face. The faces are flat (shields and seals flush with the
ring faces); rolling elements, cage and the gap between the rings are not modelled, since no catalogue dimension
gives them. Centred on the origin, axis along Z; the faces are at z = +-B/2.
