Helpful for Model Matching:
| Size / shape | Nominal sizes15/20/25/30/35/45 correspond to actual rail widths15/20/23/28/34/45 mm. H square;F1 flange top mount;F2 flange bottom mount;F3 flange top+bottom mount. N standard/L long block; size15 has noL. |
| Combined ordering | LSH [BB] [size] [H/F1/F2/F3] [N/L] [block count] X[rail length] S[first edge] [A/B/C/D preload] [N/H/P accuracy]-[fitting][-B][-T][-DD/ZZ/E]. Blank natural finish;BB black chrome. B separate packaging is not block type;T bottom-mount rail is not a joined-rail separator. |
| Preload / accuracy | A no preload/B light/C medium/D heavy;D only sizes25/30/35/45. N Normal/H High/P Precision. Accuracy and movement parallelism use mm/μm, not repeatability. Size-dependent tolerance and mounting tables retained as official drawings. |
| Fittings by size | 15:M4/AM6/LM6;20/25/30/35:M6/A01/AM8/L01/LM8/SM6;45:P01/A01/AM8/L01/LM8/SP01. Confirm elbow/straight fitting and surrounding clearance; nipple and tubing connector are different options. |
| Rail layout | Sizes15/20/25/30/35/45: pitch60/60/60/80/80/105mm; standard S/E40/40/40/55/55/67.5mm; min5/6/7/8/8/11; max55/54/53/72/72/94; maximum individual rail4040/4040/4040/4030/4030/4020mm. BB black chrome maximum3m per rail, longer needs consultation. |
| Hole-layout confirmation | L=(n−1)P+S+E. The half-pitch guidance differs from the listed standard/table margins. Confirm end distances against the size-specific table and installation drawing. Layouts with fewer than two holes or limited block space require drawing review; these are matching checks, not manufacturer prohibitions. Rail length is not travel. |
| Joined / separate parts | Joined code differs from Xlength/Sedge and needs group/joint-marking confirmation. Natural joined max12080mm for15/20/25;12030 for30/35;12000 for45;BB two rails6m/three9m, greater by consultation. Separate block BK and rail RL group codes alter preload; no random interchangeability. Uncut exampleX4000 differs from table max4040; confirm actual cut/layout. |
| Dynamic / static ratings | C/C0 in kN:15N11.3/17.9;20N18.6/28.6;20L22.2/37.6;25N26.9/39.4;25L32.9/53.0;30N37.4/55.0;30L45.7/73.1;35N50.8/72.3;35L61.9/96.1;45N80.7/110.3;45L98.5/146.9. Static moments are kN·m, not N·m or kg payload. Confirm actual force, moments, speed and required life. |
| Mounting torque | Table uses N·cm, not N·m. Iron/cast/aluminium:15 M4 412/274/206;20 M5 882/588/441;25 M6 1370/921/686;30/35 M8 3040/2010/1470;45 M12 11800/7840/5880. Parallelism/level error inμm assumes500mm rail spacing; actual spacing changes allowance. Verify datum chamfer/height. |
| Lubrication / service | Factory grease equivalent to Shell EP2; use matching lithium grease. First fill move at least three block lengths and repeat twice. Suggested replenishment100km or3–6months adjusted to service. Grease guidance applies speeds up to60m/min, not a universal series speed limit. Oil viscosity30–150cSt; higher-load/speed oil feeding and fitting clearance need confirmation. |
| Dust construction | DD dual scraper;ZZ scraper plus metal plate. Both increase total block length; do not substitute standard dimensions. Manufacturer dust-test conditions are not our customer case or universal life guarantee. |
| Self-lubricating construction | E reservoir/felt lubricator adds total length and5–7N drag. Reduced lubrication maintenance does not mean lifetime maintenance-free. Source LSH20 test30m/min,1200mm stroke,ISO VG680 uses20% oil after1000km; extrapolated4000km is conditional, not guaranteed refill interval. |
| Variant body length | Size/type: standard/DD/ZZ/E total C mm:15N60/67/64.5/75.5;20N76.5/84.5/81/93.5;20L90.5/98.5/95/107.5;25N83.5/91.5/88/100.5;25L105/113/109.5/122;30N95.5/103.5/100.5/112.5;30L118/126/123/135;35N109/118/114/126;35L134.5/143.5/139.5/151.5;45N132/141/137/152.5;45L164/173/169/184.5. Other dimensions must follow the matching shape drawing. |

AirTAC LSH standard linear guide family. Send the full code, label or drawing to confirm guide size, block shape/count, rail layout, preload, accuracy, lubrication and construction before quotation. Include required travel, load/moments, quantity and destination.
Standard is the family baseline. DD dual scrapers and ZZ scraper/metal plate are dust variants;E is reservoir/felt self-lubrication with increased length and drag. Match actual drawings. E reduces lubrication frequency;maintenance and service life depend on operating conditions. Send existing code or drawing for confirmation.
