Airtac LSH Linear Guide Rail LSH20HN1X600S20AN-M6
The AirTAC Airtac LSH Linear Guide Rail LSH20HN1X600S20AN-M6 is a standard-type profile linear guide on a 20 mm wide rail. Four rows of balls contact X-shaped raceways at a 45° angle, so the guide carries load equally in all four directions and absorbs small mounting errors inside the carriage instead of binding.

About the Airtac LSH Linear Guide Rail LSH20HN1X600S20AN-M6
The LSH20HN1X600S20AN-M6 arrives as one assembled unit: a 600 mm profile rail, 20 mm wide, carrying a single compact square block of standard length. Balls circulate through four raceways set at 45 degrees in an X pattern, giving the same load capacity in every direction and letting the carriage take up small alignment faults in the mounting face.
Dynamic rating is 18.6 kN and static is 28.6 kN per carriage; moment ratings sit at 0.27 / 0.25 / 0.25 kN.m. Each block leaves the factory charged with 1.8 cm3 of Mobilux EP2, and the schedule is 0.6 cm3 top-ups every 100 km of travel or every 3 to 6 months - on a short-stroke machine cycling steadily, the distance rule tends to bite before the calendar does.

Model Code: Airtac LSH Linear Guide Rail LSH20HN1X600S20AN-M6
| LSH | LSH Series Linear Guide. |
|---|---|
| 20 | Size code. |
| H / F1 / F2 / F3 | Carriage style: square, or flange mounted from the top, bottom, or both. |
| N | Standard carriage. |
| 1X600 | 1 carriage on a 600 mm rail. |
| S… | End-hole offset from the rail end, in mm. |
| A | A — no preload — higher preload raises rigidity and tightens how flat the mounting surface must be. |

Where the Airtac LSH Linear Guide Rail LSH20HN1X600S20AN-M6 Is Used
Fastener-feed escapement gate
Guides the escapement gate on a bolt-feeding station, where 0.6 cm3 grease top-ups every 100 km keep lubrication inside the maintenance shift plan.
Straightening-press worktable
Moves a short worktable under a manual straightening press; the 28.6 kN static rating carries clamping loads with the axis parked between strokes.
Parcel-sorter diverter arm
Replaces a worn guide on a diverter arm above a parcel sorter; the complete 600 mm set is mounted and aligned as one unit, sparing a two-part build.
Is the Airtac LSH Linear Guide Rail LSH20HN1X600S20AN-M6 the Right Guide?
Duty first: if 18.6 kN dynamic and 0.27 kN.m of moment feel generous for the job, the smaller AirTAC LRM series may carry it in a tighter envelope - its ratings are not published, so ask us to confirm them. If the load hangs off the block, remember that a long carriage lifts the moment rating faster than the load rating, and one size up to LSH25 lifts MR further still. Where the stroke is short and the priority is crossed-roller stiffness over long recirculating travel, LGC is the sensible cross-grade.
Before ordering, tick off: set or spare part, size 20 against both load and moment, square standard carriage, one block on a 600 mm rail, accuracy N with no preload, and the M6 side fitting (a choice worth double-checking for clearance on flange blocks, though this square body takes it cleanly). Carriage-only spares share the LSH20 model prefix, so a worn block can be renewed without re-laying the rail.
Quick checklist
- ✓ Complete set, carriage only, or rail only?
- ✓ Worst-case moment, not just straight load
- ✓ Travel length and mounting space
- ✓ Accuracy grade and preload
- ✓ Mounting surface ground or finish-milled
- ✓ Pairing code, if replacing a part
Installation & Maintenance Notes
- check Mounting surface must be ground or finish-milled.
- check Torque the rail screws per the recommended figures, in sequence.
- check Keep the mounting corner radius inside the stated R maximum.
- check Do not angle the carriage onto the rail; balls can drop out.
- check Drive the supplied bolt caps into the mounting holes.
- check Re-grease every 100 km of travel or every 3–6 months.
- check Installation by qualified personnel per AirTAC docs.
Airtac LSH Linear Guide Rail LSH20HN1X600S20AN-M6 FAQ
Size 20, standard-length carriage: dynamic load rating C 18.6 kN, static C0 28.6 kN, moment ratings MR 0.27 / MP 0.25 / My 0.25 kN.m, grade N parallelism band 12 to 37 um, M5 fixing screws at 882 / 588 / 441 N.cm for steel, cast iron and aluminium beds, and lubrication of 1.8 cm3 at first charge followed by 0.6 cm3 every 100 km or 3 to 6 months.
One assembled linear guide: a 600 mm rail and its factory-matched square carriage, plain finish, no preload. AirTAC LSH carriages and rails of the same model are interchangeable - any block fits any rail of that model and keeps its smoothness, preload and accuracy - so a spare carriage ordered later under the same prefix will run on this rail without re-matching.
