Notes

• 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.
