Airtac LSH Linear Guide Rail LSH20HN1X480S15AN-M6
The AirTAC Airtac LSH Linear Guide Rail LSH20HN1X480S15AN-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 LSH20HN1X480S15AN-M6
This order is a complete slide: a 480 mm LSH20 profile rail with a 15 mm end-hole offset, carrying one standard-length square carriage at normal accuracy with no preload and an M6 fitting. The size 20 rail measures 20 mm wide. Four ball rows contact X-arranged arc raceways at 45 degrees, two points per ball, which equalises capacity in all four directions and lets the carriage absorb slight mounting errors without binding.
Lubrication is the figure to watch at this travel: the carriage ships with 1.8 cm3 of Mobilux EP2, takes 0.6 cm3 per top-up, and needs re-greasing every 100 km of travel or every 3 to 6 months, whichever comes first. At a 20 m/min average traverse, 100 km arrives after roughly 83 running hours, so a fast duty hits the distance limit well before the calendar does. Ratings per standard carriage: 18.6 kN dynamic, 28.6 kN static, 0.27 / 0.25 / 0.25 kN.m MR / MP / My.

Where the Airtac LSH Linear Guide Rail LSH20HN1X480S15AN-M6 Is Used
Bottling line indexing table
A bottling line indexing table advances bottles one pitch per cycle; the 100 km re-grease mark falls neatly on the plant's quarterly maintenance window.
High-speed pick-and-place base axis
A pick-and-place base axis sweeping several hundred millimetres at up to 20 m/min reaches the 100 km grease mark within days of continuous running, so the M6 nipple is placed for gun access.
Sliding-table panel saw retrofit
Retrofitting the fence carriage of a sliding-table panel saw, the 480 mm rail covers the fence traverse and the plain finish suits a dusty woodshop on a regular greasing routine.
Is the Airtac LSH Linear Guide Rail LSH20HN1X480S15AN-M6 the Right Guide?
Match the series to duty cycle as well as load. For long continuous traverses, a recirculating ball guide with its 100 km grease interval is the right shape of product; for light, slow duty in a compact envelope, look at LRM, whose ratings are not published and which we confirm for you; for short strokes where crossed-roller stiffness matters more than long travel, look at LGC. If the moment governs, the long LSH20 carriage reaches 0.35 kN.m MR and LSH25 reaches 0.44 kN.m. Checklist: form (this is a set), size by load and moment, carriage style and length, count, rail length, accuracy and preload trade-off, grease fitting, and the pairing code if replacing a part.
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 LSH20HN1X480S15AN-M6 FAQ
Per standard carriage: 18.6 kN dynamic, 28.6 kN static, moments 0.27 / 0.25 / 0.25 kN.m (MR / MP / My); normal accuracy running parallelism 12-37 um across the rail length band. Rail mounting: M5 screws at 882 N.cm steel, 588 N.cm cast iron, 441 N.cm aluminium. Lubrication: 1.8 cm3 Mobilux EP2 first charge, 0.6 cm3 top-up, re-greased every 100 km of travel or every 3 to 6 months, whichever comes first.
No. Preload sets rigidity, not grade accuracy. This set is normal accuracy, 12-37 um running parallelism, with no preload, which is the most forgiving to install: 130 um height error and 25 um parallelism error allowed at 500 mm rail spacing. Choosing light or medium preload would tighten those allowances to 85 / 50 um and 20 / 18 um in exchange for a stiffer slide, so specify preload only when your mounting surfaces are known to be good.
