Airtac LSH Linear Guide Rail LSH30HL2X1320S20AN-M6
The AirTAC Airtac LSH Linear Guide Rail LSH30HL2X1320S20AN-M6 is a standard-type profile linear guide on a 28 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 LSH30HL2X1320S20AN-M6
LSH30HL2X1320S20AN-M6 is a matched complete set: one 1320 mm LSH profile rail with two long square carriages factory-fitted to it. Four rows of balls sit in 45 degree X-arranged arc raceways with two-point contact per ball, so loads from above, below, the side or as moments all find the same capacity, and small machining errors in the mounting face are taken up inside the carriage rather than causing binding. Size 30 is a code, not a width - the rail is 28 mm across, and a layout drawn from the size number alone will be 2 mm out.
At 1320 mm this rail uses about a third of the 4030 mm maximum length available in size 30, leaving room to order a longer axis later without changing series or tooling. Per long carriage the ratings are C 45.7 kN, C0 73.1 kN and MR/MP/My of 0.88 / 0.91 / 0.91 kN.m. Static capacity runs roughly 1.6 times dynamic on this size, but travel life is governed by the dynamic figure, so size the axis on 45.7 kN rather than on the larger static number.

Model Code: Airtac LSH Linear Guide Rail LSH30HL2X1320S20AN-M6
| LSH | LSH Series Linear Guide. |
|---|---|
| 30 | Size code — note the rail is 28 mm wide, not 30 mm. |
| H / F1 / F2 / F3 | Carriage style: square, or flange mounted from the top, bottom, or both. |
| L | Long carriage. |
| 2X1320 | 2 carriages on a 1320 mm rail. |
| S… | End-hole offset from the rail end, in mm. |
| A | A — no preload — higher preload raises rigidity and tightens how flat the mounting surface must be. |
| N | N — normal grade. |
| -M4 / -M6 / -A01… | Grease nipple or tube-fitting type. Restricted by size: size 15 the M4 family, 20–35 the M6 family, 45 the PT1/8 family. |

Where the Airtac LSH Linear Guide Rail LSH30HL2X1320S20AN-M6 Is Used
Assembly cell lift axis
A vertical lift axis in an automated assembly cell reverses under load every cycle; 73.1 kN static per long carriage holds the stopped position, and the 1320 mm rail covers the full lift stroke.
Press feeder table
The feed table of a bar or tube straightening press pushes work against eccentric loads; moment ratings of 0.88 / 0.91 / 0.91 kN.m per carriage absorb the offset without twisting the slide.
Palletiser lift column
An end-of-line palletiser raises its gripper on two guide columns; two carriages per rail share the payload and resist tipping along the lift direction at two separated points.
Is the Airtac LSH Linear Guide Rail LSH30HL2X1320S20AN-M6 the Right Guide?
Plan the axis length first: at 1320 mm this rail sits well inside the 4030 mm maximum for size 30, so a future longer stroke can stay in the same series and mounting practice. If the real duty is light and the envelope small, LRM is the smaller step - its load ratings are not published, so ask us and we will confirm them against your duty. If travel is short and the job wants crossed-roller stiffness rather than long recirculating travel, LGC fits better than any recirculating guide.
Match checklist: form (a complete set here - rail plus two long square carriages), size chosen on load AND moment, accuracy N, preload A for the widest mounting tolerance, M6 nipple. For spare-part buying, the same rail and carriages also exist as separate carriage-only and rail-only codes linked by a pairing letter - get that letter off the original part before ordering.
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 LSH30HL2X1320S20AN-M6 FAQ
Per long carriage, catalogue ratings are C 45.7 kN dynamic, C0 73.1 kN static and moments MR 0.88, MP 0.91, My 0.91 kN.m; the set carries two carriages, so a rigidly bridged load can call on both. Accuracy N running parallelism is 12-37 um depending on rail length. Mounting: M8 screws at 3040 N.cm in steel, 2010 in cast iron, 1470 in aluminium, shoulder corner radius max 1 mm. Lubrication: 7.2 cm3 Mobilux EP2 pre-filled per carriage, 2.2 cm3 top-up every 100 km of travel or every 3 to 6 months.
Preload clamps the ball rows against their raceways, so any mounting error pushes back harder. On this size, allowable parallelism error P at 500 mm rail spacing falls from 40 um (preload A, this listing) to 30 um at light B and 27 um at medium C, while allowable height error S falls from 170 um to 110 and then 90 um. The self-aligning feature absorbs only error within these limits, and whether the rail is pulled flat to its datum and torqued correctly has a large effect on the accuracy you actually achieve. Decide the preload grade before cutting the mounting surface.
