Airtac LSH Linear Guide Rail LSH15HN1X340S20AN-M4
The AirTAC Airtac LSH Linear Guide Rail LSH15HN1X340S20AN-M4 is a standard-type profile linear guide on a 15 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 LSH15HN1X340S20AN-M4
On this LSH15HN1X340S20AN-M4, the 340 mm hardened rail and its single square standard-length block ship as one set. The block's ball circuit runs over four rows of arc raceways angled at 45 degrees in an X pattern, two contact points per ball, so downward load, uplift and side thrust all draw on the same capacity, and slight misalignment of the mounting face is taken up inside the block rather than showing up as rough travel. End mounting holes sit 20 mm inboard (code S20), the accuracy grade is normal and the fit carries no preload.
A 340 mm rail leaves enormous headroom: the LSH15 series runs to 4040 mm maximum length, so a longer stroke can be ordered in one piece if the machine grows. Ratings per block are 11.3 kN dynamic, 17.9 kN static and 0.12 kN.m on each moment axis. One consequence worth acting on: a single block has limited resistance to tipping along the travel, so where the load overhangs, a second block on the same rail is the cheapest way to steady it - specify the code with 2 blocks.

Where the Airtac LSH Linear Guide Rail LSH15HN1X340S20AN-M4 Is Used
Bottling line gate slide
A gate that swings into the bottle path needs a slide that shrugs off the sideways hit of a misaligned bottle. Equal capacity in all four directions and 17.9 kN static rating handle the abuse; normal grade keeps the cost down.
Panel edge-guiding fixture
In sheet-metal work, a guide carriage running along a 340 mm edge keeps a panel square during folding or welding, and the block's self-alignment tolerates a welded base frame's minor distortion.
Small parcel diverter rail
Sortation stations use short slides to kick parcels between belts. This 340 mm set gives the stroke, and the 0.12 kN.m moment axes carry the offset pusher force without overloading the ball circuit.
Is the Airtac LSH Linear Guide Rail LSH15HN1X340S20AN-M4 the Right Guide?
This is the complete form: rail and block together, ready to bolt down. If you are repairing rather than building, check whether the old rail is reusable - if so, a carriage-only LSH15BK part with the correct pairing letter costs around a quarter of a full set. Size against both load and moment: 11.3 kN and 0.12 kN.m suit compact slides; where an overhung load dominates the calculation, the LSH20 size raises the moment rating to 0.27 kN.m, while a long LSH15 block or a second block on this rail each address tipping in their own way. Below this size, the LRM miniature series fits small envelopes, though its load ratings are unpublished and need confirming. Where the stroke is short and crossed-roller rigidity beats long-travel smoothness, LGC is the alternative. Final checks: form, size by load and moment, carriage style and length, block count and rail length, accuracy grade and preload weighed against mounting tolerance, grease fitting, and pairing code for part-only orders.
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 LSH15HN1X340S20AN-M4 FAQ
One block: dynamic C 11.3 kN, static C0 17.9 kN, moments MR 0.12, MP 0.12, My 0.12 kN.m. N grade running parallelism 12-37 um. Fix the rail with M4 screws at 412 N.cm (steel), 274 N.cm (cast iron) or 206 N.cm (aluminium), and respect the 3.5 mm mounting shoulder with corner radii no greater than 0.5 mm. Grease per block: 0.9 cm3 first charge, 0.3 cm3 top-up, every 100 km of travel or 3 to 6 months.
The rail covers a 340 mm envelope with holes 20 mm from each end, and the series itself stretches to 4040 mm if you later need more travel. One block, though, has limited anti-tipping capacity along the direction of travel: if the load overhangs, either order a two-block version of this same code or move to a long block. For moment-led sizing, remember the step to LSH20 more than doubles MR, from 0.12 to 0.27 kN.m.
