Airtac LSH Linear Guide Rail LSH20HN1X450S15AN-M6
The AirTAC Airtac LSH Linear Guide Rail LSH20HN1X450S15AN-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 LSH20HN1X450S15AN-M6
A 450 mm profile rail with a 15 mm end-hole offset carrying one standard-length LSH20 square carriage at normal accuracy, no preload, M6 fitting: that is the whole of this order code. The size 20 rail is 20 mm wide. Inside the block, four rows of balls ride X-shaped raceways cut at 45 degrees, two contact points per ball, so downward, side and uplift loads all rate identically and small misalignment of the mating surfaces is absorbed within the carriage.
With 450 mm of rail, the standard carriage keeps most of the length as usable travel once its own footprint and the end clearances are deducted, so this is the code to pick when the axis has outgrown a 400 mm layout. Ratings per carriage: 18.6 kN dynamic, 28.6 kN static, moments 0.27 / 0.25 / 0.25 kN.m MR / MP / My. A single carriage on a long rail is a tipping risk for overhung loads along the travel; a second carriage on the same rail addresses that directly, and any carriage of this model runs on any rail of this model, keeping its preload and accuracy.

Where the Airtac LSH Linear Guide Rail LSH20HN1X450S15AN-M6 Is Used
Case erecting machine vacuum traverse
A case erecting machine pulls its vacuum head across the blank magazine; the 450 mm rail lets the head dwell clear of the stack between cycles.
Vision camera traverse over assembly line
A vision inspection camera riding a 350 mm traverse over an assembly belt stays square to the product thanks to the 12-37 um normal grade parallelism.
In-circuit test head positioning
An in-circuit test fixture positions its probe head over successive board nests; the 28.6 kN static rating holds the head steady during each press-down.
Is the Airtac LSH Linear Guide Rail LSH20HN1X450S15AN-M6 the Right Guide?
Work stroke out first: rail length minus carriage length and end clearances. If the load is tall or overhung along the travel, specify two carriages on this rail rather than stepping up a size, because a second carriage resists tipping, while moving to LSH25 instead raises MR from 0.27 to 0.44 kN.m, about 63 percent. Light duty in a tight envelope may suit LRM, whose ratings we confirm since they are not published; short travels needing roller rigidity suit LGC. Checklist: form (this is a set), load and moment sizing, carriage style and length, carriage count, rail length, accuracy and preload with the mounting trade-off, grease fitting, and the pairing code for replacements.
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 LSH20HN1X450S15AN-M6 FAQ
Per standard LSH20 carriage: 18.6 kN dynamic, 28.6 kN static, MR / MP / My of 0.27 / 0.25 / 0.25 kN.m, normal accuracy parallelism of 12-37 um by rail length. Rail screws are M5 at 882 / 588 / 441 N.cm on steel, cast iron and aluminium; mounting shoulder H is 4.3 mm with a corner radius of 0.5 mm maximum. Grease: 1.8 cm3 initial charge, 0.6 cm3 top-up, re-grease every 100 km of travel or every 3 to 6 months.
Keep one carriage for compact, centrally supported loads; it gives 18.6 kN dynamic and 0.27 kN.m MR. For tall or overhung loads, run two carriages on the same rail: they share the load, resist tipping at the ends of the stroke, and carriages of the same model are interchangeable on any LSH20 rail while keeping preload and accuracy. Order the second carriage as a carriage-only code quoting the pairing letter from this order.
