Airtac LSH Linear Guide Rail LSH20HN2X3060S30AN-M6
The AirTAC Airtac LSH Linear Guide Rail LSH20HN2X3060S30AN-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 LSH20HN2X3060S30AN-M6
A complete long-travel LSH20 set: a single 3060 mm profile rail carrying two square standard-length carriages, both pre-filled with Mobilux EP2 and served by M6 fittings. The ball circuit uses four rows of balls on 45 degree X raceways, giving the same rating whether the load presses down, lifts, or pushes the block sideways, and small flatness faults in the machine bed are taken up inside the carriage. The 20 in the size code is honest here: the rail really is 20 mm wide.
At 3060 mm this rail sits 980 mm below the 4040 mm maximum length for size 20, so there is room to re-spec a longer drop-in rail later if the machine grows. Each block carries 18.6 kN dynamic and 28.6 kN static; the pair, spaced widely along a rail of this length, is the standard answer to a load that wants to tip as it travels. N-grade running parallelism spans 12 to 37 um, so a long straight datum under the rail does more for travel accuracy than any accuracy upgrade at this grade.

Where the Airtac LSH Linear Guide Rail LSH20HN2X3060S30AN-M6 Is Used
Laser marking bridge
A flying-mark head sweeping 3 m over sheet stock needs the long travel of this rail and the twin-block spacing to keep the head square at speed.
Carton divert line
A pusher swinging cartons off a 3 m conveyor runs its guide at low block load but a very high cycle count, which suits the 100 km grease clock.
Pallet labelling gantry
A print-apply head riding a 3060 mm rail beside a palletising line sees sideways loads when a label misfires, taken equally by the four-row ball geometry.
Is the Airtac LSH Linear Guide Rail LSH20HN2X3060S30AN-M6 the Right Guide?
Choose this set when travel, not load, defines the axis - conveyors, sliding doors, long shuttles. If the envelope is small or the duty light, the slimmer LRM is an option, but we must confirm its load figures with the factory since they are not published. Where the load is cantilevered, compare the moment route: the LSH20 long carriage raises MR to 0.35 kN.m, and LSH25 to 0.44 kN.m, against 0.27 here. Short-travel jobs needing crossed-roller stiffness belong to LGC instead. Your checklist: matched-set form, size by both load and moment, carriage style and length, two blocks on one 3060 mm rail, N accuracy with no preload for the widest mounting tolerance, M6 grease fitting, and a pairing code only for part replacement.
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 LSH20HN2X3060S30AN-M6 FAQ
Per square standard block: C 18.6 kN dynamic, C0 28.6 kN static, MR 0.27 / MP 0.25 / My 0.25 kN.m. N grade gives 12 to 37 um running parallelism. Rail screws are M5, torqued to 882 N.cm on steel, 588 on cast iron, 441 on aluminium. Lubricate with Mobilux EP2: 1.8 cm3 per block at first charge, 0.6 cm3 top-ups, every 100 km run or 3 to 6 months, whichever comes first. Over a 3060 mm rail that distance accumulates quickly, so log the metres.
It can, but this SKU is preload A (none) for a reason. Over a 3060 mm span the mounting surface is the accuracy limit: without preload you may run 25 um parallelism and 130 um height error between rails at 500 mm spacing, while light preload B cuts the height allowance to 85 um and medium C to 50 um. Rigidity is bought with installation precision. Fit the rail dead flat against its datum, torque every M5 screw, and seat every bolt cap flush so swarf cannot enter the ball circuit on a rail this long.
