  "basis": "Fridle's V-ring catalogue tables for VA (shaft 2.7 to 174 mm, 40 sizes) and the first six VS sizes, compared against Dichtomatik's V-ring catalogue for the first ten VA sizes; numbers only",

  "notes": [
   "Columns follow Fridle's headings: code, shaft diameter d, d2 max and d2 min (given as d plus an offset), b1 mounting width (installed width of the ring, with tolerance), d1 ring diameter, W profile height, B profile width and b2. The catalogue does not define the letters in words, and the figure is not in the text, so no further meaning is read into them. 40 VA rows are tabulated (VA0003 to VA0170, shaft 2.7 to 174 mm); Fridle's VA table ends at VA0170; Dichtomatik's list continues to VA50-2000 (the larger sizes were not read).",
   "Cross-check with Dichtomatik (VA 50 NBR, metric; its part types VA50-3 to VA50-16): its columns use other letters (h1, H, d2, d1, H1), and for the first ten sizes the values are numerically the same as Fridle's: Dichtomatik h1 = Fridle b2, H = B, H1 = b1 (for example VA50-10: h1 3.4, H 5.5, H1 4.5 ± 0.6; Fridle VA0010: b2 3.4, B 5.5, b1 4.5 ± 0.6), and its d2 = shaft + 1 or + 2, d1 = shaft + 4, + 6 or + 9 equal Fridle's d2 max and d2 min. The shaft ranges differ at the top end of the bands: Dichtomatik prints 2.7 to 3.5, 3.5 to 4.5, 4.5 to 5.5, 5.5 to 6.5, 6.5 to 8, 8 to 9.5, 9.5 to 11.5, 11.5 to 12.5, 13.5 to 15.5, 15.5 to 17.5 against Fridle's narrower 2.7 to 3.4 ... 15.5 to 17.0 (last column); both are shown and the ring series is the same, so choose by the maker you buy from.",
   "VS (the wider-profile type) is tabulated only for its first six sizes (VS006 to VS014); VL and the sizes above VA0170 are not given: the VL table could not be read cleanly (one ring-diameter value was a misprint in the source) and larger sizes were not read. Fridle's page also prints a surface-roughness line (Rmax 10 to 16 µm, Rz 6.3 to 10 µm, Ra 1.6 to 3.2 µm) without saying which surface it applies to, speed figures of 8, 8 and 12 m/s that cannot be matched to types, a shaft misalignment limit of 1° and NBR / FPM temperature ranges (-40 to +100 °C and -20 to +180 °C); these are not used further.",
   "Rotary seal vs stackable V-ring: this page covers the axial shaft-mounted V-ring (a flinger). McMaster-Carr's V-ring page also lists PTFE and leather stackable V-ring packing seals (for valves, pumps and cylinders), which are a different product; they are not tabulated here.",
   "No file: the ring's section (body, lip, hinge) is not published as numbers beyond W, B and b1, so a model would be invented. McMaster-Carr sells shaft-mounted V-rings with per-part STEP; its page is linked, not copied."

The catalogue does not define the letters in words, and the figure is not in the text, so no further meaning is read into them. 40 VA rows are tabulated (VA0003 to VA0170, shaft 2.7 to 174 mm); Fridle's VA table ends at VA0170; Dichtomatik's list continues to VA50-2000 (the larger sizes were not read).\n- Cross-check with Dichtomatik (VA 50 NBR, metric; its part types VA50-3 to VA50-16): its columns use other letters (h1, H, d2, d1, H1), and for the first ten sizes the values are numerically the same as Fridle's: Dichtomatik h1 = Fridle b2, H = B, H1 = b1 (for example VA50-10: h1 3.4, H 5.5, H1 4.5 ± 0.6; Fridle VA0010: b2 3.4, B 5.5, b1 4.5 ± 0.6), and its d2 = shaft + 1 or + 2, d1 = shaft + 4, + 6 or + 9 equal Fridle's d2 max and d2 min. The shaft ranges differ at the top end of the bands: Dichtomatik prints 2.7 to 3.5, 3.5 to 4.5, 4.5 to 5.5, 5.5 to 6.5, 6.5 to 8, 8 to 9.5, 9.5 to 11.5, 11.5 to 12.5, 13.5 to 15.5, 15.5 to 17.5 against Fridle's narrower 2.7 to 3.4 ... 15.5 to 17.0 (last column); both are shown and the ring series is the same, so choose by the maker you buy from.\n- VS (the wider-profile type) is tabulated only for its first six sizes (VS006 to VS014); VL and the sizes above VA0170 are not given: the VL table could not be read cleanly (one ring-diameter value was a misprint in the source) and larger sizes were not read. Fridle's page also prints a surface-roughness line (Rmax 10 to 16 µm, Rz 6.3 to 10 µm, Ra 1.6 to 3.2 µm) without saying which surface it applies to, speed figures of 8, 8 and 12 m/s that cannot be matched to types, a shaft misalignment limit of 1° and NBR / FPM temperature ranges (-40 to +100 °C and -20 to +180 °C); these are not used further.\n- Rotary seal vs stackable V-ring: this page covers the axial shaft-mounted V-ring (a flinger). McMaster-Carr's V-ring page also lists PTFE and leather stackable V-ring packing seals (for valves, pumps and cylinders), which are a different product; they are not tabulated here.\n- No file: the ring's section (body, lip, hinge) is not published as numbers beyond W, B and b1, so a model would be invented. McMaster-Carr sells shaft-mounted V-rings with per-part STEP; its page is linked, not copied.\n\ncode  shaft d (mm)  d2 max  d2 min  b1 (mounting width)  d1  W  B  b2  Dichtomatik (same ring)\nVA0003  2.7 – 3.4  d+1  d+4  2.5±0.3  2.5  1.5  3.0  2.1  VA50-3: shaft 2.7 – 3.5\nVA0004  3.5 – 4.4  d+1  d+6  3.0±0.4  3.2  2.0  3.7  2.4  VA50-4: shaft 3.5 – 4.5\nVA0005  4.5 – 5.4  d+1  d+6  3.0±0.4  4.0  2.0  3.7  2.4  VA50-5: shaft 4.5 – 5.5\nVA0006  5.5 – 6.4  d+1  d+6  3.0±0.4  5.0  2.0  3.7  2.4  VA50-6: shaft 5.5 – 6.5\nVA0007  6.5 – 7.5  d+1  d+6  3.0±0.4  6.0  2.0  3.7  2.4  VA50-7: shaft 6.5 – 8\nVA0008  8.0 – 9.0  d+1  d+6  3.0±0.4  7.0  2.0  3.7  2.4  VA50-8: shaft 8 – 9.5\nVA0010  9.5 – 11.0  d+2  d+9  4.5±0.6  9.0  3.0  5.5  3.4  VA50-10: shaft 9.5 – 11.5\nVA0012  11.5 – 12.0  d+2  d+9  4.5±0.6  10.5  3.0  5.5  3.4  VA50-12: shaft 11.5 – 12.5\nVA0014  13.5 – 15.0  d+2  d+9  4.5±0.6  12.5  3.0  5.5  3.4  VA50-14: shaft 13.5 – 15.5\nVA0016  15.5 – 17.0  d+2  d+9  4.5±0.6  14.0  3.0  5.5  3.4  VA50-16: shaft 15.5 – 17.5\nVA0018  17.5 – 18.5  d+2  d+9  4.5±0.6  16.0  3.0  5.5  3.4  —\nVA0020  19.0 – 20.5  d+2  d+12  6.0±0.8  18.0  4.0  7.5  4.7  —\nVA0022  21.0 – 23.5  d+2  d+12  6.0±0.8  20.0  4.0  7.5  4.7  —\nVA0025  24.0 – 26.5  d+2  d+12  6.0±0.8  22.0  4.0  7.5  4.7  —\nVA0028  27.0 – 28.5  d+2  d+12  6.0±0.8  25.0  4.0  7.5  4.7  —\nVA0030  29.0 – 30.5  d+3  d+12  6.0±0.8  27.0  4.0  7.5  4.7  —\nVA0032  31.0 – 32.5  d+3  d+12  6.0±0.8  29.0  4.0  7.5  4.7  —\nVA0035  33.0 – 35.5  d+3  d+12  6.0±0.8  31.0  4.0  7.5  4.7  —\nVA0038  36.0 – 37.5  d+3  d+12  6.0±0.8  34.0  4.0  7.5  4.7  —\nVA0040  38.0 – 42.0  d+3  d+15  7.0±1.0  36.0  5.0  9.0  5.5  —\nVA0045  43.0 – 47.0  d+3  d+15  7.0±1.0  40.0  5.0  9.0  5.5  —\nVA0050  48.0 – 52.0  d+3  d+15  7.0±1.0  45.0  5.0  9.0  5.5  —\nVA0055  53.0 – 57.0  d+3  d+15  7.0±1.0  49.0  5.0  9.0  5.5  —\nVA0060  58.0 – 62.0  d+3  d+15  7.0±1.0  54.0  5.0  9.0  5.5  —\nVA0065  63.0 – 67.0  d+3  d+15  7.0±1.0  58.0  5.0  9.0  5.5  —\nVA0070  68.0 – 72.0  d+4  d+18  9.0±1.2  63.0  6.0  11.0  6.8  —\nVA0075  73.0 – 77.0  d+4  d+18  9.0±1.2  67.0  6.0  11.0  6.8  —\nVA0080  78.0 – 82.0  d+4  d+18  9.0±1.2  72.0  6.0  11.0  6.8  —\nVA0085  83.0 – 87.0  d+4  d+18  9.0±1.2  76.0  6.0  11.0  6.8  —\nVA0090  88.0 – 92.0  d+4  d+18  9.0±1.2  81.0  6.0  11.0  6.8  —\nVA0095  93.0 – 97.0  d+4  d+18  9.0±1.2  85.0  6.0  11.0  6.8  —\nVA0100  98.0 – 104.0  d+4  d+18  9.0±1.2  90.0  6.0  11.0  6.8  —\nVA0110  105.0 – 114.0  d+4  d+21  10.5±1.5  99.0  7.0  12.8  7.9  —\nVA0120  115.0 – 124.0  d+4  d+21  10.5±1.5  108.0  7.0  12.8  7.9  —\nVA0130  125.0 – 134.0  d+4  d+21  10.5±1.5  117.0  7.0  12.8  7.9  —\nVA0140  135.0 – 144.0  d+4  d+21  10.5±1.5  126.0  7.0  12.8  7.9  —\nVA0150  145.0 – 154.0  d+4  d+21  10.5±1.5  135.0  7.0  12.8  7.9  —\nVA0160  155.0 – 164.0  d+5  d+24  12.0±1.8  144.0  8.0  14.5  9.0  —\nVA0170  165.0 – 174.0  d+5  d+24  12.0±1.8  153.0  8.0  14.5  9.0  —\nVS006  5.5 – 6.4  d+1  d+6  4.5±0.4  5.0  2.0  5.2  3.9  —\nVS007  6.5 – 7.5  d+1  d+6  4.5±0.4  6.0  2.0  5.2  3.9  —\nVS008  8.0 – 9.0  d+1  d+6  4.5±0.4  7.0  2.0  5.2  3.9  —\nVS010  9.5 – 11.0  d+2  d+9  6.7±0.6  9.0  3.0  7.7  5.6  —\nVS012  11.5 – 13.0  d+2  d+9  6.7±0.6  10.5  3.0  7.7  5.6  —\nVS014  13.5 – 15.0  d+2  d+9  6.7±0.6  12.5  3.0  7.7  5.6  —\n\nFiles elsewhere (not hosted by Xem Studio; license as stated by the publisher):\n- Fridle: V-rings catalogue: VA, VS, VL tables (code, shaft diameter d, d2 max / min, mounting width b1, ring diameter d1, profile height W, profile width B, b2) — web — Publisher's page; dimensions are facts — https://www.fridle.com/wp/media/2025/06/V-RINGS.pdf\n- Dichtomatik (V-ring catalogue, 'v-rings_en'): V-rings VA 50 / VS 50 / VL NBR and FKM, metric: part no., type, shaft range, h1, H, d2, d1, H1 — web — Publisher's page; dimensions are facts — https://elektrotanya.com/sites/default/files/forum/2015/04/v-rings_en.pdf\n- McMaster-Carr: V-ring seals (shaft-mounted rotary seals, PTFE and leather stackable V-ring packing) (free STEP/IGES per part, for your own design use; no redistribution) — STEP, IGES, PDF — McMaster-Carr site terms: personal design use, no redistribution [verify license at link] — https://www.mcmaster.com/products/v-ring-seals\n\nNo true-size file yet: the published figures do not fix the whole shape; a measured scan is planned.\nAPI: https://xemstudio.com/api/geometry?object=v-rings-va-vs-vl\n",
