Airtac LSH Linear Guide Rail LSH20HN1X750S15AN-M6
The AirTAC Airtac LSH Linear Guide Rail LSH20HN1X750S15AN-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 LSH20HN1X750S15AN-M6
This listing is a complete LSH linear guide set: one LSH20 standard-length square carriage running on a 750 mm profile rail, supplied assembled and pre-greased. Nothing pneumatic is involved - it is a pure mechanical rolling guide. Four rows of recirculating balls ride in X-arranged arc raceways at a 45 degree contact angle with two contact points per ball, so the carriage carries equal load up, down and sideways and absorbs slight mounting-surface error internally instead of binding. Size 20 means a rail that is 20 mm wide.
Per carriage the catalogue gives a dynamic rating C of 18.6 kN and a static C0 of 28.6 kN, with allowable moments MR 0.27, MP 0.25 and My 0.25 kN.m. C0 sits roughly one and a half times above C across the range; size on C, not the bigger static figure, when predictable travel life is the goal. Grade H running parallelism spans 7-28 um over the length band, and 750 mm leaves wide headroom under the 4040 mm maximum for size 20 rails if you later extend the stroke.

Where the Airtac LSH Linear Guide Rail LSH20HN1X750S15AN-M6 Is Used
Long-stroke pick-and-place gantry
A 750 mm rail gives roughly 650 mm of usable travel for a pick-and-place unit shifting housings between two conveyor lanes; the square carriage keeps the gripper plate flat under mixed vertical and side loads.
Packaging line glue head
Traversing a hot-glue or labelling head across cartons on a packaging conveyor suits one carriage on a mid-length rail - a single block aligned against a machined datum strip keeps the install simple.
Quick-change fixture slide
On an assembly bench that swaps fixtures between stations, this set carries the sliding plate; grade H parallelism of 7-28 um keeps fixture pins tracking true at every stop along the 750 mm run.
Is the Airtac LSH Linear Guide Rail LSH20HN1X750S15AN-M6 the Right Guide?
Work the checklist before ordering: form (this is a full set, rail and carriage together), size by load AND moment, carriage style (H square here, F1 or F2 flange if you mount through the top or from below), carriage length, count, rail length, accuracy grade, preload and grease fitting. If the duty is light and the envelope tight, step down to the LRM series - its load ratings are not published, so we confirm them by RFQ. If moment governs instead, a long LSH20 carriage lifts MR from 0.27 to 0.35 kN.m, about 30 percent, against only a 19 percent gain in C, so cantilevered loads usually follow the moment figure. For short travel that needs crossed-roller rigidity rather than long recirculating travel, look across to LGC. This code carries no preload, grade H accuracy, an S15 end offset and an M6 grease fitting.
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 LSH20HN1X750S15AN-M6 FAQ
Per carriage: dynamic rating C 18.6 kN, static C0 28.6 kN, allowable moments MR 0.27, MP 0.25 and My 0.25 kN.m. Grade H running parallelism is 7-28 um over the length band. Rail fixing uses M5 screws torqued to 882 N.cm into steel, 588 N.cm into cast iron and 441 N.cm into aluminium. Each carriage ships pre-filled with about 1.8 cm3 of Mobilux EP2; top up 0.6 cm3 every 100 km of travel or every 3 to 6 months, whichever comes first.
No preload (code A) gives the most installation latitude: at 500 mm rail spacing the allowable parallelism error is 25 um and the allowable height error 130 um, scaling with actual spacing. Ordering a B or C preload code instead tightens those windows to 20/85 um and 18/50 um respectively - the carriage runs stiffer, but your machined mounting surface has to earn it. For a 750 mm general-duty slide, the unloaded fit is normally the right call.
