Pillow block units UCP204–UCP210, UCF204–UCF210, UCFL204–UCFL209: bore, centre height, bolt spacing, slots — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/pillow-block-units-ucp-ucf-ucfl/ (sheet CC BY 4.0) Basis: FYH catalogue (via Misumi) and Ignera's catalogue for UCP, agreeing on the key columns; UCF from Ignera, UCFL from FYH; McMaster-Carr linked for CAD Catalog version: 2026-10-20 Sizes: see table below - UCP, UCF and UCFL are mounted ball bearing units: a UC insert bearing (spherical OD, set-screw bore) in a cast-iron housing. UCP is the two-bolt pillow block (foot mounts to a surface), UCF a four-bolt square flange, UCFL a two-bolt rhombic (oval) flange. The first digits are the bore: UCP204 = 20 mm shaft, UCP205 = 25, 206 = 30, 207 = 35, 208 = 40, 209 = 45, 210 = 50; small 8 to 17 mm printer blocks (KP08, KFL08) are on the bearing-housings page. - UCP numbers: the FYH catalogue (via Misumi, headings d H L A J N N1 H1 H2 L1 B S) and Ignera's catalogue (headings d H1 A E P S1 S2 H2 H B F) agree on the shaft d, centre height, length, bolt spacing J, base width A, slot N, bearing width B and S for 204 to 209; UCP210 is Ignera's row, confirmed on the key columns by an FYH scan (H 57.2, L 206, J 159, A 60, N 20, H1 21, H2 113, B 51.6, S 19). Differences are shown in the cells: base thickness H1 (14 / 15 against 16 for UCP204 / 205), total height H2 (UCP205 70 against 71, UCP207 95 against 93, UCP208 98 against 100). N1 (FYH 18 to 21, Ignera 19 to 23) disagrees on every row and is left out. - UCF numbers are Ignera's table (headings d A E C G L S Z B F, bolt size); the letters differ between catalogues and are not defined in the text, so they are kept as printed, with only the unambiguous ones read: A is the flange side, E the bolt spacing, S the hole, B the bearing width (it equals the UCP and UCFL B column on every size). FYH's scrambled UCF page agrees on the 204 / 205 rows (86 / 95 side, 64 / 70 bolt spacing, 33.3 / 35.8). C (flange thickness) and G are single-source and ambiguous against the FYH columns, so G is left out. - UCFL numbers (204 to 209) are the FYH table via Misumi; the UCFL205 row equals the FYH page via AIMS Industrial. B equals the UCP B column on every size. The bolt column is the bolt the slot / hole N takes. - McMaster-Carr's pillow blocks and block bearings are linked as the per-part CAD source; the category page was readable only as inch filter values, so none of its numbers are mixed in. - Files: none. The cast housings have a spherical bore pocket, a grease boss and a web whose outline is not in the tables; a solid from these numbers would be invented. - Left out: UCP201 to 203 (12 to 17 mm), UCP211 and larger, UCPH high-base, UCPA tapped base, UCT take-up, KP / KFL 000 to 005 (the tables read were unlabelled), UCFC round flange, grease fitting, load ratings, mass. unit shaft d, mm centre height H, mm length L, mm bolt spacing J, mm base width A, mm bolt slot N, mm base thickness H1, mm total height H2, mm L1, mm bearing width B, mm S, mm bolt size UCP204 20 33.3 127 95 38 13 16 (Ignera 14) 65 36 31 12.7 M10 UCP205 25 36.5 140 105 38 13 16 (Ignera 15) 70 (Ignera 71) 38 34.1 14.3 M10 UCP206 30 42.9 165 121 48 17 17 84 48 38.1 15.9 M14 UCP207 35 47.6 167 127 48 17 18 95 (Ignera 93) 47 42.9 17.5 M14 UCP208 40 49.2 184 137 54 17 18 98 (Ignera 100) 53 49.2 19 M14 UCP209 45 54 190 146 54 17 20 106 55 49.2 19 M14 UCP210 50 57.2 206 159 60 20 21 113 60 (FYH via AIMS) 51.6 19 M16 UCF204 (square flange) 20 A 86 square bolt spacing E 64 C 15 L 25.5 S 12 (hole) Z 33.3 B 31 F 12.7 — — M10 UCF205 (square flange) 25 A 95 square bolt spacing E 70 C 16 L 27 S 12 (hole) Z 35.8 B 34.1 F 14.3 — — M10 UCF206 (square flange) 30 A 108 square bolt spacing E 83 C 18 L 31 S 12 (hole) Z 40.2 B 38.1 F 15.9 — — M10 UCF207 (square flange) 35 A 117 square bolt spacing E 92 C 19 L 34 S 14 (hole) Z 44.4 B 42.9 F 17.5 — — M12 UCF208 (square flange) 40 A 130 square bolt spacing E 102 C 21 L 36 S 16 (hole) Z 51.2 B 49.2 F 19 — — M14 UCF209 (square flange) 45 A 137 square bolt spacing E 105 C 22 L 38 S 16 (hole) Z 52.2 B 49.2 F 19 — — M14 UCF210 (square flange) 50 A 143 square bolt spacing E 111 C 22 L 40 S 16 (hole) Z 54.6 B 51.6 F 19 — — M14 UCFL204 (rhombic flange) 20 H 113 L 60 A 25.5 J 90 N 12 A1 11 A2 15 A0 33.3 B 31 S 12.7 M10 UCFL205 (rhombic flange) 25 H 130 L 68 A 27 J 99 N 16 A1 13 A2 16 A0 35.8 B 34.1 S 14.3 M14 UCFL206 (rhombic flange) 30 H 148 L 80 A 31 J 117 N 16 A1 13 A2 18 A0 40.2 B 38.1 S 15.9 M14 UCFL207 (rhombic flange) 35 H 161 L 90 A 34 J 130 N 16 A1 14 A2 19 A0 44.4 B 42.9 S 17.5 M14 UCFL208 (rhombic flange) 40 H 175 L 100 A 36 J 144 N 16 A1 14 A2 21 A0 51.2 B 49.2 S 19 M14 UCFL209 (rhombic flange) 45 H 188 L 108 A 38 J 148 N 19 A1 15 A2 22 A0 52.2 B 49.2 S 19 M16 Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - FYH catalogue (via Misumi): Pillow block units UCP: d, H, L, A, J, N, N1, H1, H2, L1, B, S (page 84) — web — Publisher's page; dimensions are facts — https://mx.c.misumi-ec.com/en/book/FYH1_SEA_01/pdf/0084.pdf - Ignera (mounted units catalogue): UCP pillow blocks 204 to 210: d, H1, A, E, P, S1, S2, H2, H, B, F — web — Publisher's page; dimensions are facts — https://www.ignera.lt/image/catalog/product/UCP-cx.pdf - Ignera (mounted units catalogue): UCF square flange units 204 to 210: d, A, E, C, G, L, S, Z, B, F — web — Publisher's page; dimensions are facts — https://www.ignera.lt/image/catalog/product/UCF-cx.pdf - FYH catalogue (via Misumi): UCFL rhombic flange units 201 to 209: d, H, L, A, J, N, A1, A2, A0, B, S (page 176) — web — Publisher's page; dimensions are facts — https://mx.c.misumi-ec.com/en/book/FYH1_SEA_01/pdf/0176.pdf - FYH catalogue (via AIMS Industrial): UCP / UCFL / UCF pages 82 to 113 (used only to cross-check UCP210, UCFL204 and UCFL205) — web — Publisher's page; dimensions are facts — https://aimsindustrial.com.au/cdn/shop/files/FYH-Mounted-Bearing-Units-Catalogue-Pages-84-88.pdf - FYH catalogue (via AIMS Industrial): UCFL pages 110-113 (UCFL205 row used as a cross-check) — web — Publisher's page; dimensions are facts — https://aimsindustrial.com.au/cdn/shop/files/FYH-Mounted-Bearing-Units-Catalogue-Pages-110-113.pdf - McMaster-Carr: Pillow blocks (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/pillow-blocks/ - McMaster-Carr: Block (mounted) bearings (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/block-bearings No true-size file yet: the published figures do not fix the whole shape; a measured scan is planned.
