Airtac LSH Linear Guide Rail LSH25HN2X580S20AN-M6
The AirTAC Airtac LSH Linear Guide Rail LSH25HN2X580S20AN-M6 is a standard-type profile linear guide on a 23 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 LSH25HN2X580S20AN-M6
Order code LSH25HN2X580S20AN-M6 breaks down as a size 25 complete set - one 580 mm rail, two standard-length square carriages, no preload (A), normal accuracy (N), M6 grease fittings - delivered as carriages running on their rail, not as loose parts. The ball circuit uses four rows of X-arranged raceways at a 45 degree contact angle; because each ball seats at two points, the carriage rides out small flatness or height errors in the machine bed by flexing internally rather than jamming.
Mounting quality decides the accuracy you actually get, whatever the grade. The LSH25 shoulder figures are H 6.5, H1 5 and H2 5 mm with a base corner radius of no more than 1 mm, and the M6 clamping screws want 1370 N.cm in steel, 921 in cast iron, 686 in aluminium - pulled flat against the datum face before final torque. Per-carriage ratings are C 26.9 kN and C0 39.4 kN with moment limits of 0.44 / 0.38 / 0.38 kN.m (MR / MP / My). The rail is 23 mm wide despite the 25 in the code, and the S20 offset puts the end-fixing holes 20 mm in from each rail end.

Model Code: Airtac LSH Linear Guide Rail LSH25HN2X580S20AN-M6
| LSH | LSH Series Linear Guide. |
|---|---|
| 25 | Size code — note the rail is 23 mm wide, not 25 mm. |
| H / F1 / F2 / F3 | Carriage style: square, or flange mounted from the top, bottom, or both. |
| N | Standard carriage. |
| 2X580 | 2 carriages on a 580 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. |
| N | N — normal grade. |
| -M4 / -M6 / -A01… | Grease nipple or tube-fitting type. Restricted by size: size 15 the M4 family, 20–35 the M6 family, 45 the PT1/8 family. |

Where the Airtac LSH Linear Guide Rail LSH25HN2X580S20AN-M6 Is Used
Pick-and-place over a biscuit line
A vacuum gripper shuttles biscuits from a conveyor onto trays along this 580 mm guide; the S20 end-fixing holes land on a standard 20 mm drilled pattern, and grade N accuracy is ample for tray pick positions.
PCB transfer unit in an SMT line
An edge-belt transfer module slides its conveyor section on this set between loader and reflow infeed; two blocks keep the 580 mm beam level under the offset weight of the drive motor.
Cartoning machine glue head
A hot-melt applicator tracks along the flap-folding station of a cartoner; the no-preload setting tolerates the slightly uneven aluminium base extrusion, and M6 fittings allow a grease top-up at each changeover.
Is the Airtac LSH Linear Guide Rail LSH25HN2X580S20AN-M6 the Right Guide?
If you are sizing from scratch, start with the trap: the size code 25 does not mean a 25 mm rail, the true width is 23 mm, so check your slot or shoulder layout first. Then size by load and moment together - for an off-centre or overhung mass, moment usually decides, and two carriages on this 580 mm rail already double the moment reach to 0.88 kN.m MR. Light duty in a small envelope points down to LRM (load ratings unpublished, we confirm them case by case); a heavier moment points up to LSH30 at MR 0.66 kN.m or to the long LSH25L block at MR 0.58 kN.m; short-travel work needing crossed-roller stiffness points across to LGC. Final checklist: complete set or spare part, size, carriage style and length, count, rail length, accuracy and preload with the mounting-tolerance trade-off in mind (no-preload allows 130 um height error at 500 mm spacing, medium preload only 70 um), M6 fitting, and the pairing code if you are buying a replacement block on its own.
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 LSH25HN2X580S20AN-M6 FAQ
Each LSH25 standard carriage is rated C 26.9 kN dynamic and C0 39.4 kN static, with MR / MP / My moments of 0.44 / 0.38 / 0.38 kN.m; with two carriages the moment reach doubles. Grade N running parallelism spans 12 to 37 um depending on rail length. Fasten the 23 mm rail with M6 screws torqued to 1370 / 921 / 686 N.cm on steel / cast iron / aluminium. Grease per carriage: 3.6 cm3 first charge, 1.1 cm3 top-up, refreshed every 100 km of travel or every 3 to 6 months.
You receive the complete set: one 580 mm rail with the two square carriages mounted and free to travel, plus the bolt caps for the mounting screw holes - drive every cap fully into its counterbore or swarf will reach the ball circuit. Because rail and carriages come together, no pairing code is needed now; keep the model code, though, since a future spare carriage ordered on its own must match the rail's pairing code.
