Airtac LSH Linear Guide Rail LSH20HN1X1380S30AH-M6
The AirTAC Airtac LSH Linear Guide Rail LSH20HN1X1380S30AH-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 LSH20HN1X1380S30AH-M6
The LSH20HN1X1380S30AH-M6 ships as one complete guide assembly: a 1380 mm rail of true 20 mm width, drilled with the first mounting hole 30 mm in from each end, carrying a single standard-length square block. Four ball rows run at 45 degree contact angle in crossed arc grooves, giving the same load capacity in every direction and enough self-alignment to soak up small flatness errors in the machine bed.
At 1380 mm this rail sits comfortably inside the 4040 mm maximum length for LSH20, so longer cuts remain available in the same series. High accuracy is the grade here, so the running parallelism sits in the 7 to 28 um band. Ratings are 18.6 kN dynamic and 28.6 kN static per carriage with MR of 0.27 kN.m. Plan lubrication by distance, not by the calendar: at a 1000 mm stroke cycled every ten seconds the block covers 100 km in about twelve days, so the grease interval falls due well before the three-month mark.

Where the Airtac LSH Linear Guide Rail LSH20HN1X1380S30AH-M6 Is Used
Benchtop router gantry
A 1380 mm rail carries the Y-axis of a light benchtop router or foam cutter, where the square block resists cutting forces arriving from any direction.
Gantry pick over a conveyor
Spanning a 1.2 m conveyor with a vacuum pick needs a rail of about this length; a second block, orderable in the series, would add tipping resistance along the travel.
Label applicator traverse
A print-and-apply labeller sweeping its head across cartons uses roughly this stroke; the M6 fitting sits in the block side for fast top-ups through long production runs.
Is the Airtac LSH Linear Guide Rail LSH20HN1X1380S30AH-M6 the Right Guide?
For a 1380 mm span, check the moment first when the load overhangs: an L-long carriage raises MR about 30 percent against a 19 percent gain in C, and a second block on the rail (orderable in this series) resists tipping along the travel. Downsize to LRM only where loads are light and the housing is small - we verify its unpublished ratings for you. Where the stroke is short and the priority is crossed-roller rigidity, compare LGC instead. Before ordering, settle the checklist: set versus carriage-only versus rail-only, size against both C and MR, block style and length, block count and rail length, accuracy and preload remembering that tighter preload demands a truer mounting surface, grease fitting, and the pairing code if matching to existing parts. After mounting, drive the supplied bolt caps fully into the rail holes, seated flush, so swarf cannot reach the ball circuit.
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 LSH20HN1X1380S30AH-M6 FAQ
Per standard-length carriage: C 18.6 kN, C0 28.6 kN and moments of 0.27 (MR), 0.25 (MP) and 0.25 (My) kN.m; a rail on its own has no rating. This high-accuracy rail runs parallel within 7-28 um. Fasten with M5 screws - 882 N.cm in steel, 588 in cast iron, 441 in aluminium. Lubricate with 1.8 cm3 at first charge and 0.6 cm3 at each top-up through the M6 fitting, every 100 km or three to six months.
This set is preload A (none), which allows 130 um of height error and 25 um of parallelism per 500 mm of rail spacing - the most forgiving combination. Light preload B tightens those to 85 and 20 um, medium C to 50 and 18 um. Over a 1380 mm span the machining and shimming effort to hold grade C grows quickly, so choose preload only when the rigidity gain is genuinely needed. The grade is fixed in the order code, so specify it at ordering rather than trying to adjust it afterwards.
