# Radial shaft seals / oil seals, DIN 3760 and ISO 6194-1 sizes: shaft d × bore D × width b (6 × 16 × 7 to 480 × 530 × 25) + case envelopes

> What are the standard sizes of metric oil seals (shaft d × bore D × width b), such as 10 × 22 × 7 or 25 × 40 × 7?

- Category: Hardware › Bearings, rails & motion
- Kind: Standard part
- Basis: ISO 6194-1:2007 nominal-size table (free sample pages; ISO 6194-1:1982 sample read for comparison), cross-checked against McMaster-Carr's printed metric shaft seals; 51 case envelopes as files
- Page: https://xemstudio.com/objects/radial-shaft-seals-din-3760-iso-6194/ · JSON: https://xemstudio.com/api/geometry?object=radial-shaft-seals-din-3760-iso-6194 · Plain text: https://xemstudio.com/objects/radial-shaft-seals-din-3760-iso-6194/sheet.txt

**Exact dimensions.** Every file is drawn at true size with no tolerance added. The holes and pins that meet another part are listed below under Mating features, with the fit each joint needs; open those by your process's clearance before making the part.

## 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.

## Questions

**What size oil seal for a 25 mm shaft?**

25 × 40 × 7, 25 × 47 × 7 and 25 × 52 × 7 are in the ISO 6194-1:2007 sample table (shaft 25, bore 40 / 47 / 52, width 7); McMaster-Carr lists the same three.

**What is the housing bore for a 10 × 22 × 7 oil seal?**

22 mm (the D), 7 mm wide: ISO 6194-1 lists 10 × 22 × 7 and 10 × 25 × 7 for a 10 mm shaft. The bore tolerance is H8 (see oil-seal-housing-and-shaft-din-3760).

**Is 12 × 22 × 7 a standard oil seal size?**

It is sold as a DIN 3760 size (Tameson), but it is not in the ISO 6194-1:2007 sample table, which lists 12 × 24 × 7, 12 × 25 × 7 and 12 × 30 × 7 for a 12 mm shaft.
