ISO 199-2014 pdf free.Rolling bearings – Thrust bearings – Geometrical product specification (GPS) and tolerance values.
ISO 199 specifies dimensional characteristics, limit deviations from nominal values, and tolerance values to define the interface (except chamfers) of thrust rolling bearings. Nominal boundary dimensions are defined in Iso 104111.
This International Standard is not applicable to certain thrust bearings (e.g. thrust needle roller bearings) or for particular fields of application (e.g. special thrust precision bearings). Tolerances for such bearings are given in the relevant International Standards.
Chamfer dimension limits are given in ISO 5821l.

3 Terms and definitions
For the purposes of this document, the terms and definitions in ISO 5593, ISO 14405-1, and ISO/TS 17863 apply.
4 Symbols
To express that the ISO/GPS system, ISO 8015 121 is applied, the dimensional characteristics shall be included in the technical product documentation (for example on the drawing). The dimensional specifications, associated to these characteristics, are described in Table 1 and Figures 1 to 4.
Descriptions for symbols are in accordance with GPS terminology; relationships with traditional terms are described in Annex A.
A tolerance value associated to a characteristic is symbolized by t followed by the symbol for characteristic, for example, tdnip.
In this International Standard, the ISO default specification operator for size is in accordance with ISO 14405-1, i.e. the two-point size is valid. Some specification modifiers are described in Annex D.
The detailed definitions for terms in ISO 14405-1 and traditional terms in ISO 1132-1141 are not fully equal, for differences, see Annex C.ISO 199 pdf free download.
