   "Flanged linear bushings (flange linear bearings, flanged ball bushings) are an LM-type linear bushing with a flange on one end: the body drops into a bored plate and the flange screws to its face. LMF has a round flange, LMK a square flange, LMH an oval (two-flat) flange. The d column is the shaft diameter the ball set runs on (LM8 = 8 mm shaft); UU means a seal at each end; L after the number (LMF8LUU) is the long version. The numbers here are the Asian (JIS-style) LM series that Samick, THK, Misumi and the 3D-printer parts sold as LMF8UU, LMK10UU, LMF12UU follow. McMaster-Carr's 440C stainless flange-mounted bearings use the same sizes (see below).",
   "Sources and cross-checks: LMF numbers are Samick's catalogue and a second catalogue (DriveHQ, maker not named) with identical d, D, L, D1, H, PCD and hole columns for 6 to 60 mm. LMK numbers are Tuli's datasheet; its d, D, L, H and PCD equal the LMF columns for every size, and its K equals the square-flange column of the DriveHQ catalogue for sizes 6 to 30. McMaster's 440C flange-mounted metric bearings (round: 6, 8, 10, 12, 16, 20, 25, 30, 40 mm; square: 6 to 25 mm) agree on length, flange size, bolt circle and OD for every size where they overlap. THK's LMH table (flats K = the catalogue's W, hole pitch B and C = the catalogue's A and F) matches the DriveHQ catalogue for sizes 6 to 30; for 16 mm and up B × C is a rectangle whose diagonal equals the PCD.",
   "Disagreements, shown rather than averaged: LMF40LUU is 154 long and LMF60LUU 211 long (Samick, DriveHQ, WF International), but the square-flange LMK40LUU / LMK60LUU are 151 / 209 (Tuli, Misumi) and McMaster lists a 60 mm round-flange bushing at 209. THK's LMH10 flange is Ø39 where the LMF10 flange is Ø40. The LMK hole sizes (3.5 × 6 × 3.1 for 6 to 8 mm and so on) differ slightly from LMF's (3.4 × 6.5 × 3.3); both are as printed. LMH hole counts are not stated in the text: for LMH up to 13 mm only one pitch (= the PCD) is printed, from 16 mm a B × C rectangle on the PCD.",
   "Hole count: LMK has four mounting holes (Makerstore product text; Tuli's LMF page says a circular flange has 4 holes for fixing). The tables give hole Ø d1, counterbore Ø d2 and depth h as one 'd1 × d2 × h' column; the counterbore is on the outer flange face (the face the body does not stand out of) in the files, which is the usual way to screw a flange bushing to a plate, but the text tables do not say so. Square-flange LMK holes sit on the diagonals of the square (a hole on the axis would run off the edge for the small sizes).",
   "Files: 20 solids (LMF and LMK, UU and long LUU, for 8, 10, 12, 16 and 20 mm shafts): a body Ø D with the bore d, a flange at one end flush with the end face, four holes on the PCD with counterbores. No ball tracks, retainer, wiper seals or ring grooves (those numbers are on the LM..UU page and are not drawn). The bore is the nominal shaft diameter, the bore of the bushing before your clearance; the shaft is on the linear-shafts page. Pocket in the plate: body OD D (press or slide per the mating table), flange recess optional.",
   "Left out: the other sizes as files (6, 13, 25 to 80 mm are in the table only), LMH files (hole positions are only partly printed), steel-retainer (A) variants, load ratings, tilt/squareness tolerances, LMF80UU (Samick lists D1 164, H 18, PCD 142; a single source) and the inch (McMaster) sizes. LMEF / LMHP / LMFP (guided or elliptical flange) are different series and not covered."

 "sheet_text": "Flanged linear bushings LMF, LMK, LMH (and long LUU): bore, OD, length, flange size, bolt circle, hole + counterbore, 6 to 60 mm + STEP/STL (8 to 20 mm) — dimension sheet\nSource: Xem Studio, https://xemstudio.com/objects/flanged-linear-bushings-lmf-lmk-lmh/  (sheet CC BY 4.0)\nBasis: Samick LMF / LMF..L catalogue, Tuli LMK / LMK..LUU datasheets, THK LMH tables; cross-checked against a second catalogue, McMaster's flange-mounted bearings and each other; McMaster-Carr linked for CAD\nCatalog version: 2026-10-20\n\nSizes: see table below\n- Flanged linear bushings (flange linear bearings, flanged ball bushings) are an LM-type linear bushing with a flange on one end: the body drops into a bored plate and the flange screws to its face. LMF has a round flange, LMK a square flange, LMH an oval (two-flat) flange. The d column is the shaft diameter the ball set runs on (LM8 = 8 mm shaft); UU means a seal at each end; L after the number (LMF8LUU) is the long version. The numbers here are the Asian (JIS-style) LM series that Samick, THK, Misumi and the 3D-printer parts sold as LMF8UU, LMK10UU, LMF12UU follow. McMaster-Carr's 440C stainless flange-mounted bearings use the same sizes (see below).\n- Sources and cross-checks: LMF numbers are Samick's catalogue and a second catalogue (DriveHQ, maker not named) with identical d, D, L, D1, H, PCD and hole columns for 6 to 60 mm. LMK numbers are Tuli's datasheet; its d, D, L, H and PCD equal the LMF columns for every size, and its K equals the square-flange column of the DriveHQ catalogue for sizes 6 to 30. McMaster's 440C flange-mounted metric bearings (round: 6, 8, 10, 12, 16, 20, 25, 30, 40 mm; square: 6 to 25 mm) agree on length, flange size, bolt circle and OD for every size where they overlap. THK's LMH table (flats K = the catalogue's W, hole pitch B and C = the catalogue's A and F) matches the DriveHQ catalogue for sizes 6 to 30; for 16 mm and up B × C is a rectangle whose diagonal equals the PCD.\n- Disagreements, shown rather than averaged: LMF40LUU is 154 long and LMF60LUU 211 long (Samick, DriveHQ, WF International), but the square-flange LMK40LUU / LMK60LUU are 151 / 209 (Tuli, Misumi) and McMaster lists a 60 mm round-flange bushing at 209. THK's LMH10 flange is Ø39 where the LMF10 flange is Ø40. The LMK hole sizes (3.5 × 6 × 3.1 for 6 to 8 mm and so on) differ slightly from LMF's (3.4 × 6.5 × 3.3); both are as printed. LMH hole counts are not stated in the text: for LMH up to 13 mm only one pitch (= the PCD) is printed, from 16 mm a B × C rectangle on the PCD.\n- Hole count: LMK has four mounting holes (Makerstore product text; Tuli's LMF page says a circular flange has 4 holes for fixing). The tables give hole Ø d1, counterbore Ø d2 and depth h as one 'd1 × d2 × h' column; the counterbore is on the outer flange face (the face the body does not stand out of) in the files, which is the usual way to screw a flange bushing to a plate, but the text tables do not say so. Square-flange LMK holes sit on the diagonals of the square (a hole on the axis would run off the edge for the small sizes).\n- Files: 20 solids (LMF and LMK, UU and long LUU, for 8, 10, 12, 16 and 20 mm shafts): a body Ø D with the bore d, a flange at one end flush with the end face, four holes on the PCD with counterbores. No ball tracks, retainer, wiper seals or ring grooves (those numbers are on the LM..UU page and are not drawn). The bore is the nominal shaft diameter, the bore of the bushing before your clearance; the shaft is on the linear-shafts page. Pocket in the plate: body OD D (press or slide per the mating table), flange recess optional.\n- Left out: the other sizes as files (6, 13, 25 to 80 mm are in the table only), LMH files (hole positions are only partly printed), steel-retainer (A) variants, load ratings, tilt/squareness tolerances, LMF80UU (Samick lists D1 164, H 18, PCD 142; a single source) and the inch (McMaster) sizes. LMEF / LMHP / LMFP (guided or elliptical flange) are different series and not covered.\n\ndesignation  bore d (shaft Ø), mm  body OD D, mm  length L, mm  flange  flange thickness H, mm  bolt circle PCD, mm  hole Ø d1, mm  counterbore Ø d2 × depth h, mm\nLMF6UU  6  12  19  Ø28 round  5  20  3.4  Ø6.5 × 3.3\nLMF8SUU  8  15  17  Ø32 round  5  24  3.4  Ø6.5 × 3.3\nLMF8UU  8  15  24  Ø32 round  5  24  3.4  Ø6.5 × 3.3\nLMF10UU  10  19  29  Ø40 round  6  29  4.5  Ø8 × 4.4\nLMF12UU  12  21  30  Ø42 round  6  32  4.5  Ø8 × 4.4\nLMF13UU  13  23  32  Ø43 round  6  33  4.5  Ø8 × 4.4\nLMF16UU  16  28  37  Ø48 round  6  38  4.5  Ø8 × 4.4\nLMF20UU  20  32  42  Ø54 round  8  43  5.5  Ø9.5 × 5.4\nLMF25UU  25  40  59  Ø62 round  8  51  5.5  Ø9.5 × 5.4\nLMF30UU  30  45  64  Ø74 round  10  60  6.6  Ø11 × 6.5\nLMF35UU  35  52  70  Ø82 round  10  67  6.6  Ø11 × 6.5\nLMF40UU  40  60  80  Ø96 round  13  78  9  Ø14 × 8.6\nLMF50UU  50  80  100  Ø116 round  13  98  9  Ø14 × 8.6\nLMF60UU  60  90  110  Ø134 round  18  112  11  Ø17.5 × 10.8\nLMF6LUU (long)  6  12  35  Ø28 round  5  20  3.4  Ø6.5 × 3.3\nLMF8LUU (long)  8  15  45  Ø32 round  5  24  3.4  Ø6.5 × 3.3\nLMF10LUU (long)  10  19  55  Ø40 round  6  29  4.5  Ø8 × 4.4\nLMF12LUU (long)  12  21  57  Ø42 round  6  32  4.5  Ø8 × 4.4\nLMF13LUU (long)  13  23  61  Ø43 round  6  33  4.5  Ø8 × 4.4\nLMF16LUU (long)  16  28  70  Ø48 round  6  38  4.5  Ø8 × 4.4\nLMF20LUU (long)  20  32  80  Ø54 round  8  43  5.5  Ø9.5 × 5.4\nLMF25LUU (long)  25  40  112  Ø62 round  8  51  5.5  Ø9.5 × 5.4\nLMF30LUU (long)  30  45  123  Ø74 round  10  60  6.6  Ø11 × 6.5\nLMF35LUU (long)  35  52  135  Ø82 round  10  67  6.6  Ø11 × 6.5\nLMF40LUU (long)  40  60  154  Ø96 round  13  78  9  Ø14 × 8.6\nLMF50LUU (long)  50  80  192  Ø116 round  13  98  9  Ø14 × 8.6\nLMF60LUU (long)  60  90  211  Ø134 round  18  112  11  Ø17.5 × 10.8\nLMK6UU  6  12  19  22 × 22 square  5  20  3.5  Ø6 × 3.1\nLMK8UU  8  15  24  25 × 25 square  5  24  3.5  Ø6 × 3.1\nLMK10UU  10  19  29  30 × 30 square  6  29  4.5  Ø7.5 × 4.1\nLMK12UU  12  21  30  32 × 32 square  6  32  4.5  Ø7.5 × 4.1\nLMK13UU  13  23  32  34 × 34 square  6  33  4.5  Ø7.5 × 4.1\nLMK16UU  16  28  37  37 × 37 square  6  38  4.5  Ø7.5 × 4.1\nLMK20UU  20  32  42  42 × 42 square  8  43  5.5  Ø9 × 5.1\nLMK25UU  25  40  59  50 × 50 square  8  51  5.5  Ø9 × 5.1\nLMK30UU  30  45  64  58 × 58 square  10  60  6.6  Ø11 × 6.1\nLMK35UU  35  52  70  64 × 64 square  10  67  6.6  Ø11 × 6.1\nLMK40UU  40  60  80  75 × 75 square  13  78  9  Ø14 × 8.1\nLMK50UU  50  80  100  92 × 92 square  13  98  9  Ø14 × 8.1\nLMK60UU  60  90  110  106 × 106 square  18  112  11  Ø17 × 11.1\nLMK6LUU (long)  6  12  35  22 × 22 square  5  20  3.5  Ø6 × 3.1\nLMK8LUU (long)  8  15  45  25 × 25 square  5  24  3.5  Ø6 × 3.1\nLMK10LUU (long)  10  19  55  30 × 30 square  6  29  4.5  Ø7.5 × 4.1\nLMK12LUU (long)  12  21  57  32 × 32 square  6  32  4.5  Ø7.5 × 4.1\nLMK13LUU (long)  13  23  61  34 × 34 square  6  33  4.5  Ø7.5 × 4.1\nLMK16LUU (long)  16  28  70  37 × 37 square  6  38  4.5  Ø7.5 × 4.1\nLMK20LUU (long)  20  32  80  42 × 42 square  8  43  5.5  Ø9 × 5.1\nLMK25LUU (long)  25  40  112  50 × 50 square  8  51  5.5  Ø9 × 5.1\nLMK30LUU (long)  30  45  123  58 × 58 square  10  60  6.6  Ø11 × 6.1\nLMK35LUU (long)  35  52  135  64 × 64 square  10  67  6.6  Ø11 × 6.1\nLMK40LUU (long)  40  60  151  75 × 75 square  13  78  9  Ø14 × 8.1\nLMK50LUU (long)  50  80  192  92 × 92 square  13  98  9  Ø14 × 8.1\nLMK60LUU (long)  60  90  209  106 × 106 square  18  112  11  Ø17 × 11.1\nLMH6 (THK)  6  12  19  Ø28 with flats 18 apart  5  hole pitch 20 (one spacing printed)  3.4  Ø6.5 × 3.3\nLMH8S (THK)  8  15  17  Ø32 with flats 21 apart  5  hole pitch 24 (one spacing printed)  3.4  Ø6.5 × 3.3\nLMH8 (THK)  8  15  24  Ø32 with flats 21 apart  5  hole pitch 24 (one spacing printed)  3.4  Ø6.5 × 3.3\nLMH10 (THK)  10  19  29  Ø39 with flats 25 apart  6  hole pitch 29 (one spacing printed)  4.5  Ø8 × 4.4\nLMH12 (THK)  12  21  30  Ø42 with flats 27 apart  6  hole pitch 32 (one spacing printed)  4.5  Ø8 × 4.4\nLMH13 (THK)  13  23  32  Ø43 with flats 29 apart  6  hole pitch 33 (one spacing printed)  4.5  Ø8 × 4.4\nLMH16 (THK)  16  28  37  Ø48 with flats 34 apart  6  hole pitch 31 × 22  4.5  Ø8 × 4.4\nLMH20 (THK)  20  32  42  Ø54 with flats 38 apart  8  hole pitch 36 × 24  5.5  Ø9.2 × 5.4\nLMH25 (THK)  25  40  59  Ø62 with flats 46 apart  8  hole pitch 40 × 32  5.5  Ø9.2 × 5.4\nLMH30 (THK)  30  45  64  Ø74 with flats 51 apart  10  hole pitch 49 × 35  6.6  Ø11 × 6.5\n\nFiles elsewhere (not hosted by Xem Studio;
