Airtac LSH Linear Guide Rail LSH25HN2X1020S30AN-M6
The AirTAC Airtac LSH Linear Guide Rail LSH25HN2X1020S30AN-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 LSH25HN2X1020S30AN-M6
The LSH25HN2X1020S30AN-M6 is a complete linear guide set: one 1020 mm rail with two standard-length square carriages already matched and fitted, grade N accuracy, no preload, an M6 grease fitting in each block and the first rail hole 30 mm from the end. Inside every carriage, four rows of recirculating balls run on X-shaped arc raceways at a 45 degree contact angle, two-point contact per ball, so uplift, side thrust and downward load all meet the same rating while slight mounting-surface error is absorbed inside the block instead of binding the slide.
Per block the catalogue gives 26.9 kN dynamic and 39.4 kN static, with moment ratings of 0.44 (MR), 0.38 (MP) and 0.38 (My) kN.m, and the two blocks on this rail double those figures for the pair - the standard answer to a load that would tip a single carriage. The 1020 mm length leaves 3020 mm below the 4040 mm maximum rail length for size 25, and layout work should note the rail is 23 mm wide, not 25 mm.

Model Code: Airtac LSH Linear Guide Rail LSH25HN2X1020S30AN-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. |
| 2X1020 | 2 carriages on a 1020 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 LSH25HN2X1020S30AN-M6 Is Used
PCB placement gantry
A twin-rail bridge moving a placement head across a PCB panel: two blocks per rail share the overhung head mass, and equal capacity in all four directions holds the bridge down against uplift on fast Z-lifts.
Cartoning machine pusher
A product pusher on a cartoning line strokes a few hundred mm per cycle; two blocks on one rail stop the pusher plate from nodding as it meets carton resistance at the end of each stroke.
Vision inspection slide
A camera travelling along a glass inspection line rides grade N rails; the 12-37 um running parallelism band keeps the lens-to-part distance repeatable enough for autofocus to hold throughout the pass.
Is the Airtac LSH Linear Guide Rail LSH25HN2X1020S30AN-M6 the Right Guide?
Match the guide to both numbers: the load and the moment. A cantilevered tool often outgrows the moment rating first - the long LSH25 carriage raises MR to 0.58 kN.m, and a single step to LSH30 reaches 0.66. For light duties in a tight envelope, step down to LRM; its load ratings are not published, so we confirm them for your duty before you commit. If the travel is short and the job needs crossed-roller rigidity rather than long recirculating travel, step across to LGC. Ordering checklist: complete set form, size 25 chosen by load and moment together, square standard carriages, two per rail, 1020 mm rail with 30 mm end offset, accuracy N, preload A, M6 fitting. If you are repairing a machine instead of building one, the pairing code off the original part is what identifies the piece you need.
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 LSH25HN2X1020S30AN-M6 FAQ
Per standard-length block: dynamic C 26.9 kN, static C0 39.4 kN, moment ratings MR 0.44, MP 0.38 and My 0.38 kN.m. Accuracy N gives a running parallelism band of 12-37 um across the rail. Rail fixing screws are M6 at 1370 N.cm into steel, 921 into cast iron, 686 into aluminium. Lubrication: 3.6 cm3 first charge per block, 1.1 cm3 top-ups, repeated every 100 km of travel or every 3 to 6 months.
A complete guide, not parts: the 1020 mm rail with both square carriages fitted and the bolt caps for the mounting holes. Seat each cap fully in its counterbore, lay a flat plate over it and tap vertically with a plastic mallet, then clean the rail - a cap left standing above the rail top face lets swarf into the ball circuit. Carriage base material, weight and full dimensions are not stated in the catalogue; request the datasheet via RFQ for those.
