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 — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/radial-shaft-seals-din-3760-iso-6194/ (sheet CC BY 4.0) 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 Catalog version: 2026-10-20 Sizes: see table below - 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. d (shaft) D (housing bore) b (width) ISO 6194-1:2007 sample McMaster-Carr listing file / page 6 16 7 listed (ISO 6194-1:2007 sample) — file 6 22 7 listed (ISO 6194-1:2007 sample) — file 7 22 7 listed (ISO 6194-1:2007 sample) — file 8 22 7 listed (ISO 6194-1:2007 sample) — rotary-shaft-seal-8x22x7 8 24 7 listed (ISO 6194-1:2007 sample) — file 9 22 7 listed (ISO 6194-1:2007 sample) — file 10 22 7 listed (ISO 6194-1:2007 sample) — file 10 25 7 listed (ISO 6194-1:2007 sample) — file 12 20 5 not in the sample table McMaster lists it — 12 22 7 not in the sample table Tameson lists it as a DIN 3760 size (see radial-shaft-seal-12x22x7) radial-shaft-seal-12x22x7 12 24 7 listed (ISO 6194-1:2007 sample) — file 12 25 7 listed (ISO 6194-1:2007 sample) — file 12 30 7 listed (ISO 6194-1:2007 sample) — file 15 26 7 listed (ISO 6194-1:2007 sample) — file 15 30 7 listed (ISO 6194-1:2007 sample) — file 15 35 7 listed (ISO 6194-1:2007 sample) — file 16 30 7 listed (ISO 6194-1:2007 sample) — file 18 30 7 listed (ISO 6194-1:2007 sample) — file 18 35 7 listed (ISO 6194-1:2007 sample) — file 20 30 7 not in the sample table McMaster lists it — 20 35 7 listed (ISO 6194-1:2007 sample) McMaster lists it, b agrees file 20 40 7 listed (ISO 6194-1:2007 sample) — file 22 35 7 listed (ISO 6194-1:2007 sample) — file 22 40 7 listed (ISO 6194-1:2007 sample) — file 22 47 7 listed (ISO 6194-1:2007 sample) — file 25 40 7 listed (ISO 6194-1:2007 sample) McMaster lists it, b agrees file 25 47 7 listed (ISO 6194-1:2007 sample) McMaster lists it, b agrees file 25 52 7 listed (ISO 6194-1:2007 sample) McMaster lists it, b agrees file 28 40 7 listed (ISO 6194-1:2007 sample) — file 28 47 7 listed (ISO 6194-1:2007 sample) — file 28 52 7 listed (ISO 6194-1:2007 sample) — file 30 42 7 listed (ISO 6194-1:2007 sample) McMaster lists it, b agrees file 30 47 7 listed (ISO 6194-1:2007 sample) — file 30 52 7 listed (ISO 6194-1:2007 sample) — file 32 45 8 listed (ISO 6194-1:2007 sample) — file 32 47 8 listed (ISO 6194-1:2007 sample) — file 32 52 8 listed (ISO 6194-1:2007 sample) — file 35 47 7 not in the sample table McMaster lists it — 35 50 8 listed (ISO 6194-1:2007 sample) — file 35 52 8 listed (ISO 6194-1:2007 sample) McMaster lists it with b = 7 file 35 55 8 listed (ISO 6194-1:2007 sample) — file 38 55 8 listed (ISO 6194-1:2007 sample) — file 38 58 8 listed (ISO 6194-1:2007 sample) — file 38 62 8 listed (ISO 6194-1:2007 sample) — file 40 52 7 not in the sample table McMaster lists it — 40 55 8 listed (ISO 6194-1:2007 sample) — file 40 62 8 listed (ISO 6194-1:2007 sample) — file 42 55 8 listed (ISO 6194-1:2007 sample) — file 42 62 8 listed (ISO 6194-1:2007 sample) — file 45 62 8 listed (ISO 6194-1:2007 sample) — file 45 65 8 listed (ISO 6194-1:2007 sample) — file 50 65 8 listed (ISO 6194-1:2007 sample) McMaster lists it, b agrees file 50 72 8 listed (ISO 6194-1:2007 sample) — file 55 72 8 listed (ISO 6194-1:2007 sample) — file 55 80 8 listed (ISO 6194-1:2007 sample) — file 60 80 8 listed (ISO 6194-1:2007 sample) — file 60 85 8 listed (ISO 6194-1:2007 sample) — file 65 85 10 listed (ISO 6194-1:2007 sample) — — 65 90 10 listed (ISO 6194-1:2007 sample) — — 70 90 10 listed (ISO 6194-1:2007 sample) — — 70 95 10 listed (ISO 6194-1:2007 sample) — — 75 95 10 listed (ISO 6194-1:2007 sample) — — 75 100 10 listed (ISO 6194-1:2007 sample) — — 80 100 10 listed (ISO 6194-1:2007 sample) — — 80 110 10 listed (ISO 6194-1:2007 sample) — — 85 110 12 listed (ISO 6194-1:2007 sample) — — 85 120 12 listed (ISO 6194-1:2007 sample) — — 90 120 12 listed (ISO 6194-1:2007 sample) — — 95 120 12 listed (ISO 6194-1:2007 sample) — — 100 125 12 listed (ISO 6194-1:2007 sample) — — 110 140 12 listed (ISO 6194-1:2007 sample) — — 120 150 12 listed (ISO 6194-1:2007 sample) — — 130 160 12 listed (ISO 6194-1:2007 sample) — — 140 170 15 listed (ISO 6194-1:2007 sample) — — 150 180 15 listed (ISO 6194-1:2007 sample) — — 160 190 15 listed (ISO 6194-1:2007 sample) — — 170 200 15 listed (ISO 6194-1:2007 sample) — — 180 210 15 listed (ISO 6194-1:2007 sample) — — 190 220 15 listed (ISO 6194-1:2007 sample) — — 200 230 15 listed (ISO 6194-1:2007 sample) — — 220 250 15 listed (ISO 6194-1:2007 sample) — — 240 270 20 listed (ISO 6194-1:2007 sample) — — 260 300 20 listed (ISO 6194-1:2007 sample) — — 280 320 20 listed (ISO 6194-1:2007 sample) — — 300 340 20 listed (ISO 6194-1:2007 sample) — — 320 360 20 listed (ISO 6194-1:2007 sample) — — 340 380 20 listed (ISO 6194-1:2007 sample) — — 360 400 20 listed (ISO 6194-1:2007 sample) — — 380 420 20 listed (ISO 6194-1:2007 sample) — — 400 440 20 listed (ISO 6194-1:2007 sample) — — 450 500 25 listed (ISO 6194-1:2007 sample) — — 480 530 25 listed (ISO 6194-1:2007 sample) — — Files elsewhere (not hosted by Xem Studio;
