Angular contact ball bearings 7200 B and 7300 B (7205B, 7206B, 7305B and more): bore, OD, width, r, r1 + 23 ring-envelope STEP/STL files — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/angular-contact-ball-bearings-72xx-73xx-b/ (sheet CC BY 4.0) Basis: Koyo (JTEKT) catalogue B2001E-3 rows (d, D, B, r, r1), matched on every row against Emerson Bearing's 72xx and 73xx lists; maker product pages linked for CAD Catalog version: 2026-10-20 Sizes: see table below - Single-row angular-contact ball bearings, 'B' type, 40° contact angle: they carry radial load and axial load in one direction, so they are used in pairs (or in a double-row bearing) on wheel hubs, pumps, gearboxes and steering heads. 72xx is the light series and 73xx the heavier series: the bore code is the last two digits times 5 from 04 up (7205 = 25 mm, 7305 = 25 mm), and at the same bore a 73xx has a larger OD and width than the 72xx. - Numbers: Koyo (JTEKT) catalogue B2001E-3 for d, D, B, r and r1 (7200B to 7214B, 7217B to 7220B, 7303B to 7314B, 7317B to 7320B), with Emerson Bearing's two lists as the independent check: all 33 Koyo rows match Emerson on d, D and B. Emerson also lists 7215B, 7216B, 7221B to 7226B, 7301B, 7302B, 7315B, 7316B and 7321B to 7328B; those rows have no r / r1 here because Koyo's pages read do not include them. The Koyo rows were matched to bearing numbers by page order; agreement with Emerson on d, D and B for all 33 rows confirms the match (r and r1 are from Koyo only). - r min and r1 min are the smallest allowed chamfer sizes (the standard's boundary values), not the drawn corner. The ring envelope files round both ring faces with these minimums (r on one face, r1 on the other); the real ring corner can be larger and the thrust-face assignment is not drawn. - Files: 23 ring envelopes (7200B to 7212B and 7303B to 7312B): one solid ring with the published bore, OD, width and rounded corners. No raceways, balls, cage or ring shoulders (the shoulder heights are mounting dimensions that were not read). Use them as the space the bearing takes in a design. - Left out: other contact angles (72xx C, 72xx A, 70xx, 719xx), universal / paired sets (DB, DF, DT), sealed and shielded variants (2RS, ZZ), the mounting dimensions (shoulder diameters), load ratings and limiting speeds, inch angular-contact bearings, four-point contact bearings. bearing contact angle bore d, mm OD D, mm width B, mm r min, mm r1 min, mm source 7200B 40° 10 30 9 0.6 0.3 Koyo + Emerson 7201B 40° 12 32 10 0.6 0.3 Koyo + Emerson 7202B 40° 15 35 11 0.6 0.3 Koyo + Emerson 7203B 40° 17 40 12 0.6 0.3 Koyo + Emerson 7204B 40° 20 47 14 1 0.6 Koyo + Emerson 7205B 40° 25 52 15 1 0.6 Koyo + Emerson 7206B 40° 30 62 16 1 0.6 Koyo + Emerson 7207B 40° 35 72 17 1.1 0.6 Koyo + Emerson 7208B 40° 40 80 18 1.1 0.6 Koyo + Emerson 7209B 40° 45 85 19 1.1 0.6 Koyo + Emerson 7210B 40° 50 90 20 1.1 0.6 Koyo + Emerson 7211B 40° 55 100 21 1.5 1 Koyo + Emerson 7212B 40° 60 110 22 1.5 1 Koyo + Emerson 7213B 40° 65 120 23 1.5 1 Koyo + Emerson 7214B 40° 70 125 24 1.5 1 Koyo + Emerson 7215B 40° 75 130 25 — — Emerson (d, D, B only) 7216B 40° 80 140 26 — — Emerson (d, D, B only) 7217B 40° 85 150 28 2 1 Koyo + Emerson 7218B 40° 90 160 30 2 1 Koyo + Emerson 7219B 40° 95 170 32 2.1 1.1 Koyo + Emerson 7220B 40° 100 180 34 2.1 1.1 Koyo + Emerson 7221B 40° 105 190 36 — — Emerson (d, D, B only) 7222B 40° 110 200 38 — — Emerson (d, D, B only) 7224B 40° 120 215 40 — — Emerson (d, D, B only) 7226B 40° 130 230 40 — — Emerson (d, D, B only) 7301B 40° 12 37 12 — — Emerson (d, D, B only) 7302B 40° 15 42 13 — — Emerson (d, D, B only) 7303B 40° 17 47 14 1 0.6 Koyo + Emerson 7304B 40° 20 52 15 1.1 0.6 Koyo + Emerson 7305B 40° 25 62 17 1.1 0.6 Koyo + Emerson 7306B 40° 30 72 19 1.1 0.6 Koyo + Emerson 7307B 40° 35 80 21 1.5 1 Koyo + Emerson 7308B 40° 40 90 23 1.5 1 Koyo + Emerson 7309B 40° 45 100 25 1.5 1 Koyo + Emerson 7310B 40° 50 110 27 2 1 Koyo + Emerson 7311B 40° 55 120 29 2 1 Koyo + Emerson 7312B 40° 60 130 31 2.1 1.1 Koyo + Emerson 7313B 40° 65 140 33 2.1 1.1 Koyo + Emerson 7314B 40° 70 150 35 2.1 1.1 Koyo + Emerson 7315B 40° 75 160 37 — — Emerson (d, D, B only) 7316B 40° 80 170 39 — — Emerson (d, D, B only) 7317B 40° 85 180 41 3 1.1 Koyo + Emerson 7318B 40° 90 190 43 3 1.1 Koyo + Emerson 7319B 40° 95 200 45 3 1.1 Koyo + Emerson 7320B 40° 100 215 47 3 1.1 Koyo + Emerson 7321B 40° 105 225 49 — — Emerson (d, D, B only) 7322B 40° 110 240 50 — — Emerson (d, D, B only) 7324B 40° 120 260 55 — — Emerson (d, D, B only) 7326B 40° 130 280 58 — — Emerson (d, D, B only) 7328B 40° 140 300 62 — — Emerson (d, D, B only) Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - JTEKT (Koyo), via AIMS Industrial: Single-row angular contact ball bearings (Cat.
