Airtac LSH Linear Guide Rail LSH20HN2X2600S40AN-M6
The AirTAC Airtac LSH Linear Guide Rail LSH20HN2X2600S40AN-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 LSH20HN2X2600S40AN-M6
Order LSH20HN2X2600S40AN-M6 and you receive one continuous 2600 mm profile rail - 20 mm wide, normal (N) accuracy - carrying two standard square carriages. That single-code delivery matters on long axes: the hardened rail arrives as one piece with its end-hole offset set at 40 mm, ready to be screwed down along its full length. The four-row, 45 degree X raceway layout gives the carriage equal capacity downward, upward, sideways and against uplift, and lets the assembly self-align to small errors in a base plate 2.6 m long that is unlikely to be perfect.
Dynamic rating is 18.6 kN per carriage and static 28.6 kN, with moment limits of 0.27 / 0.25 / 0.25 kN.m (MR / MP / My). The 2600 mm length leaves 1440 mm of headroom under the 4040 mm maximum single-rail length for size 20, so a longer variant or a re-cut remains possible. Over a span this long, achieved straightness is dominated less by the N grade band of 12-37 um and more by whether the base is pulled flat: M5 screws torqued to 882 N.cm into steel, tightened along the rail in sequence, do much of the accuracy work.

Where the Airtac LSH Linear Guide Rail LSH20HN2X2600S40AN-M6 Is Used
CNC router gantry feed
A light-production CNC router runs its Y-axis beam on twin blocks over 2.6 m of travel, crossing full sheet stock in one pass without repositioning the workpiece.
Carton transfer pusher
A distribution-line pusher spans a wide conveyor, sliding on the 2600 mm rail to divert cartons across the belt with no mid-span support under the guideway.
Panel saw edge fence
A cabinet shop's panel saw uses the long rail as a moving fence held parallel to the blade line; the two carriages resist the fence tipping as sheet stock bears against it.
Is the Airtac LSH Linear Guide Rail LSH20HN2X2600S40AN-M6 the Right Guide?
For a 2.6 m axis, first decide whether the load sits between the carriages or cantilevers past them - the 0.27 kN.m MR limit per block governs the second case, and either one size up to LSH25 (MR 0.44 kN.m) or the long LSH20 carriage (MR 0.35 kN.m) buys moment more cheaply than adding blocks. If 18.6 kN dynamic per carriage is far beyond the actual load, LRM in a smaller envelope is worth a look; its ratings are not published, so ask us to confirm them against your duty. Where the real travel is short and the requirement is crossed-roller rigidity, LGC fits better than a long recirculating rail. Before ordering, tick off: form (this is a complete set), size versus load and moment, carriage style and length, number of blocks, rail length and end offset, accuracy grade, preload balanced against its mounting-tolerance cost, grease fitting - and the pairing code on the original part if this is a like-for-like 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 LSH20HN2X2600S40AN-M6 FAQ
Each standard carriage provides 18.6 kN dynamic (C) and 28.6 kN static (C0), with moment ratings MR 0.27, MP 0.25 and My 0.25 kN.m. N-grade running parallelism falls in the 12-37 um band. Rail fixing is M5 screws: 882 N.cm in steel, 588 N.cm in cast iron, 441 N.cm in aluminium. Lubrication is 1.8 cm3 of Mobilux EP2 per carriage at first fill and 0.6 cm3 top-ups, refreshed every 100 km of travel or 3 to 6 months - on a long axis the kilometres accumulate quickly, so build a greasing point into the maintenance plan.
The A grade in this code leaves the widest installation window: at 500 mm spacing, height error S up to 130 um and parallelism P up to 25 um, scaled to your actual span. Every step of preload narrows it - B to 85/20 um, C to 50/18 um - and holding a 50 um height band across a 2.6 m base plate is a serious machining job in itself. If your duty genuinely needs the rigidity of grade C, plan the tighter geometry first, then order the preload.
