92 in table

Notes

• Rows are the nominal sizes d1 (shaft) × D (housing bore) × b (width) printed in the ISO 6194-1:2007 sample pages, in mm: 87 sizes from 6 × 16 × 7 to 480 × 530 × 25. The sample's text keeps the table in four column groups of three numbers per printed line, and the groups are read that way; the standard's table also has a footnote (b may be increased for more complex seal configurations). DIN 3760 is the German standard for the same metric sizes; the sample read does not quote it, and the page does not claim that every DIN 3760 size is in this table.
• Seal styles (A, AS, B, C and so on), pressure and speed ratings are not part of this table: it gives the nominal size only. Housing and shaft rules: oil-seal-housing-and-shaft-din-3760.
• Cross-check 1, ISO 6194-1:1982 sample pages: the first 24 sizes (6 × 16 × 7 to 25 × 47 × 7) read the same. For the larger sizes the 1982 sample reads b = 7 for 45 to 60 mm shafts and 8 for 65 to 110 mm, where the 2007 sample reads 8 and 10 to 12; the 1982 text was partly scrambled, so the 2007 widths are shown and the older ones noted here. Cross-check the width you need against the standard or your seal's datasheet before cutting a housing.
• Cross-check 2, McMaster-Carr's metric shaft-seal table (11 sizes: 12 × 20 × 5, 20 × 30 × 7, 20 × 35 × 7, 25 × 40 × 7, 25 × 47 × 7, 25 × 52 × 7, 30 × 42 × 7, 35 × 47 × 7, 35 × 52 × 7, 40 × 52 × 7, 50 × 65 × 8): 20 × 35, 25 × 40, 25 × 47, 25 × 52, 30 × 42 and 50 × 65 are in the ISO sample table with the same b; 35 × 52 is there with b = 8 where McMaster lists 7; 12 × 20 × 5, 20 × 30 × 7, 35 × 47 × 7 and 40 × 52 × 7 are not in the sample table. They are shown as McMaster lists them, so a catalogue size is not necessarily an ISO 6194-1 preferred size. 12 × 22 × 7 (existing page radial-shaft-seal-12x22x7, from a Tameson listing) is also not in the sample table.
• Inch-size seals (TCM, CR, SKF / Chicago Rawhide codes) are not tabulated: no inch table with checkable numbers was read.
• Files: case envelopes, a ring of outside diameter D and bore d, width b, for the 51 sizes with d up to 60 mm except 8 × 22 × 7 (on rotary-shaft-seal-8x22x7). The bore d is the lip's nominal contact diameter; the real lip, garter spring, the rubber-covered outside and the case steps are not published as numbers, so they are not drawn. The housing it sits in is on oil-seal-housing-and-shaft-din-3760. McMaster-Carr sells shaft seals with per-part STEP; the page is linked, not copied.
