Airtac LSH Linear Guide Rail LSH20HN2X700S20AN-M6
The AirTAC Airtac LSH Linear Guide Rail LSH20HN2X700S20AN-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 LSH20HN2X700S20AN-M6
The AirTAC LSH20HN2X700S20AN-M6 code describes a complete guide assembly: a 700 mm profile rail in size 20 - exactly 20 mm wide - with two standard-length square carriages running on it, each fitted with an M6 grease nipple. Inside every carriage, four rows of balls recirculate through X-pattern arc raceways set at 45 degrees, carrying load equally in all four directions; because the raceway geometry is symmetric, small mounting-surface faults are soaked up by the carriage instead of becoming hard spots in the travel.
Two carriages on one rail change the mechanics: the pair shares the applied load so each block sees half of it, and the assembly resists tipping about the travel axis far better than a single block. Per carriage the ratings are C 18.6 kN, C0 28.6 kN and 0.27 / 0.25 / 0.25 kN.m of moment in the MR/MP/My directions. The 700 mm length still leaves over 3300 mm of headroom below the 4040 mm Lmax for size 20, so the same guide can be extended later without resorting to a spliced rail.

Model Code: Airtac LSH Linear Guide Rail LSH20HN2X700S20AN-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. |
| 2X700 | 2 carriages on a 700 mm rail. |

Where the Airtac LSH Linear Guide Rail LSH20HN2X700S20AN-M6 Is Used
Benchtop CNC router Y axis
A 700 mm Y-travel carrying a router spindle plate; two carriages share the cutting loads and resist lift-off during aggressive plunge moves.
Parcel diverter arm guide
A divert arm sweeping parcels off a warehouse sorter; the pair of blocks takes the moment as the arm reaches across the belt.
Cable traverse on a spooling machine
The traverse that lays wire evenly across a drum reciprocates constantly, so the 100 km re-grease distance arrives long before the calendar interval.
Is the Airtac LSH Linear Guide Rail LSH20HN2X700S20AN-M6 the Right Guide?
Keep three exits open when sizing. Light duty in a cramped envelope: the LRM series is smaller, but its load ratings are not published and must be confirmed per application. Moment-heavy duty: go up a size rather than sideways - LSH25 lifts MR from 0.27 to 0.44 kN.m (about 63 percent) for one part, while the long LSH20L carriage captures about 30 percent of that benefit; a second carriage, already fitted to this set, instead answers tipping along the rail. Short travel with high stiffness demand: crossed-roller LGC is the closer match than a recirculating guide. Order checklist for this SKU: complete set form, size 20, two square standard carriages, 700 mm rail, preload A, accuracy N, M6 fitting, and confirm the 20 mm end-hole offset matches your stop positions.
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 LSH20HN2X700S20AN-M6 FAQ
Per carriage: C 18.6 kN dynamic, C0 28.6 kN static, moments 0.27 (MR), 0.25 (MP) and 0.25 (My) kN.m; two carriages split the applied load between them. Parallelism bands: N 12-37 um, H 7-28 um, P 3-21 um. Mounting: M5 screws at 882 / 588 / 441 N.cm into steel, cast iron and aluminium, shoulder H 4.3 mm, corner radius R max 0.5 mm. Grease: 1.8 cm3 charge, 0.6 cm3 top-up, every 100 km of travel or every 3 to 6 months.
You receive the 700 mm rail with both square carriages fitted, plus the bolt caps that must be seated flush into the screw holes - a raised cap lets swarf into the ball circuit. The code carries no preload (A) and N accuracy. Spare carriages are listed separately under LSH20BK codes: any LSH20 carriage fits any LSH20 rail and keeps its preload and accuracy, and a replacement carriage costs roughly a quarter of a complete set, so a worn block rarely justifies scrapping a sound rail.
