Airtac LSH Linear Guide Rail LSH25F1N1X220S20AN-M6
The AirTAC Airtac LSH Linear Guide Rail LSH25F1N1X220S20AN-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 LSH25F1N1X220S20AN-M6
A single AirTAC LSH25 carriage in top-flange form rides a 220 mm rail in this assembly, sold under code LSH25F1N1X220S20AN-M6 with no preload and normal (N) accuracy. The 45 degree contact angle of the four-row ball set means the block carries downward, upward and side loads at equal ratings, and small errors in the mounting face are absorbed inside the carriage instead of forcing the balls to bind. Remember that size 25 means a 23 mm wide rail.
The figure to watch for a cantilevered tool or camera is the moment rating: MR 0.44 kN.m, alongside C 26.9 kN and C0 39.4 kN. One size up from LSH20 raises MR from 0.27 to 0.44 kN.m - about 63 percent - without adding a second carriage, which is why this block often wins on tipping loads. The 220 mm rail sits comfortably inside the 4040 mm maximum length for size 25, leaving room to re-spec a longer travel later on the same block.

Model Code: Airtac LSH Linear Guide Rail LSH25F1N1X220S20AN-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. |
| 1X220 | 1 carriage on a 220 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 LSH25F1N1X220S20AN-M6 Is Used
Gantry Z-axis lift column
A drilling or camera head hanging off the front of a vertical carriage loads MR directly; the 0.44 kN.m moment rating defines how far the head may stand proud of the block face.
UV curing lamp carrier
A curing lamp traverses 220 mm above a moving web on this carriage; the top flange accepts the lamp housing and reflector without a sub-plate.
Guide-rail adjuster slide
Packaging lines use short carriages like this to reposition forming guides between recipe sizes; the 220 mm travel covers most container width changes.
Is the Airtac LSH Linear Guide Rail LSH25F1N1X220S20AN-M6 the Right Guide?
Size the guide on the worst combination of load, lever arm and acceleration, not on C alone: a modest weight on a long bracket can exceed MR long before 26.9 kN is in play. Where the duty is genuinely light and compact, LRM steps down a class - its ratings are not published, so we verify them for your case. Where travel is short but stiffness per millimetre matters, LGC's crossed rollers are the alternative. When ordering, work through: set, carriage or rail; size by load and moment; carriage style and standard or long length; number of blocks and rail length; accuracy and preload weighed against achievable machining tolerance; grease fitting; pairing code for replacement parts.
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 LSH25F1N1X220S20AN-M6 FAQ
Per carriage: 26.9 kN dynamic, 39.4 kN static, moments 0.44 / 0.38 / 0.38 kN.m (MR / MP / My). Normal accuracy gives 12-37 um running parallelism. Rail fixing: M6 screws at 1370 N.cm (steel), 921 (cast iron), 686 (aluminium), with the supplied caps seated flush into the holes to keep swarf out of the ball circuit. Grease: 3.6 cm3 Mobilux EP2 on delivery, 1.1 cm3 top-up every 100 km of travel or every 3 to 6 months.
You receive a 220 mm rail and one fitted F1 top-flange carriage, plus bolt caps for the rail holes - drive them in below the rail top face or contamination will reach the balls. Any LSH25 carriage fits any LSH25 rail of the same model, so a replacement block ordered years later will still run true. For carriage-only or rail-only orders you must quote the pairing code, which links the part to its matching rail or block.
