BS ISO 104:2015 pdf free download.Rolling bearings — Thrust bearings — Boundary dimensions, general plan.
This International Standard specifies preferred boundary dimensions for single-direction and double- direction thrust bearings with flat back faces.
In addition, it gives the minimum bore diameters of housing washers and maximum outside diameters of shaft washers of bearings in dimension series 11, 12, 13, 14, 22, 23 and 24.
Guidelines for the extension of this International Standard for single-direction thrust bearings are given in Annex A.
NOTE Boundary dimensions for aligning thrust bearings (none flat back faces) and aligning seat washers are given in ISO 20516. [2]

5 Boundary dimensions
5.1 General
The corresponding largest single chamfer dimensions to the r s min dimensions in Tables 1 to 9 and r1s min dimensions in Tables 7 to 9 are given in ISO 582.
Chamfer dimensions r and r 1 apply only at the corners indicated in Figures 1 and 2. No dimensions are given for other corners; however, they should not be sharp.
5.2 Single-direction thrust bearings with flat back faces
Dimensions for single-direction thrust bearings with flat back faces are given in Tables 1 to 6.BS ISO 104 pdf download.
