Source levels
Main value = the modeled value (nominal, else the middle of min-max).
Grey under a value = its min-max, where the source gives both.
< / = = the source gives only that limit, modeled at it. ref = reference.
L2 = the standard itself (or its complete free preview, or the maker's drawing).
L1 = two or more independent sources agree: the release gate.
LO = one source only: printed amber and marked *.
c = a source value was corrected; the datasheet says how.
House convention = a detail no source dimensions, drawn to a stated house rule. This size's values: L18.
Notes
2 r: the sources give r_s min only; modeled at that limit.
A row is a product as sold: no suffix open, ZZ shielded (2Z), DD or VV sealed (2RS). Ring corners, faces and the shield recess are house conventions, sheet DO2. 2RS: width as the shielded bearing; sealed row not listed by the sources.
