Airtac LSH Linear Guide Rail LSH30F2N2X1080S20BP-M6
The AirTAC Airtac LSH Linear Guide Rail LSH30F2N2X1080S20BP-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 LSH30F2N2X1080S20BP-M6
The BP suffix marks this 1080 mm set as preloaded: code B applies a light preload to the ball circuit of both F2 carriages, removing the running clearance of the free version while keeping friction modest. The guide itself is the standard LSH30 profile rail, 28 mm true width, with four rows of balls seated in 45 degree X-shaped raceways - each ball touches its raceway at two points, and it is this contact the preload stiffens. The two bottom-flange carriages bolt up from beneath, so nothing projects above the carriage face where tooling would go.
Preload buys rigidity but narrows the installation window: at 500 mm rail spacing the allowable parallelism error falls from 40 um to 30 um and the allowable height error from 170 um to 110 um, both scaled to actual spacing. Per carriage the catalogue ratings hold at 37.4 kN dynamic, 55.0 kN static, and 0.66 / 0.67 / 0.67 kN.m of MR / MP / My. Split between the two carriages on one rail, load and tipping moment share the work along the travel.

Model Code: Airtac LSH Linear Guide Rail LSH30F2N2X1080S20BP-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. |
| N | Standard carriage. |
| 2X1080 | 2 carriages on a 1080 mm rail. |

Where the Airtac LSH Linear Guide Rail LSH30F2N2X1080S20BP-M6 Is Used
PCB test handler X-axis
A board test handler positions fixtures over probe fields on a 1080 mm span; light preload B removes running play so the same coordinates repeat on every indexing cycle.
Vision inspection camera rail
A camera carriage scans PCB panels along this rail; the P grade holds the optics parallel to the panel within the 3-21 um running band over the whole metre.
High-speed dispensing gantry
A glue head sweeps a metre-wide panel with direction reversals at each end; preload B stiffens the axis against the recoil, and re-grease falls due at every 100 km of accumulated travel.
Is the Airtac LSH Linear Guide Rail LSH30F2N2X1080S20BP-M6 the Right Guide?
If your mounting surfaces are machined flat and true, the light preload here rewards you with a stiffer, lower-play axis; if they are milled plates of uncertain flatness, the non-preloaded version of the same 1080 mm set forgives more installation error. Downsize to LRM for light duties in tight envelopes - we confirm its unpublished load ratings for you. Upsize to a long carriage, or to the next size which is available to order, when moment rather than dynamic load decides. Choose LGC when travel is short and crossed-roller stiffness beats long recirculating travel.
Before ordering, fix: the form (complete set, two carriages), size against load and moment, F2 mounting from below, standard carriage length, 1080 mm rail length, P accuracy grade, light preload B together with its tighter alignment call, M6 fitting, and the 20 mm end-hole offset.
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 LSH30F2N2X1080S20BP-M6 FAQ
Per carriage: C 37.4 kN dynamic, C0 55.0 kN static, static moments MR 0.66 / MP 0.67 / My 0.67 kN.m; P-grade running parallelism 3-21 um by rail length. With light preload B, installation at 500 mm rail spacing allows 30 um parallelism error and 110 um height error, proportional to actual spacing. Fasten the rail with M8 screws at 3040 / 2010 / 1470 N.cm for steel / cast iron / aluminium, with corner radius of 1 mm maximum (shoulders H 6.5, H1 5, H2 5 mm). Lubrication: 5.4 cm3 Mobilux EP2 per carriage initially, 1.7 cm3 top-ups every 100 km of travel or every 3-6 months.
You receive one 1080 mm rail with two preloaded F2 carriages already fitted, plus the bolt caps for the mounting holes - a complete matched assembly, not parts you have to pair up. If you later need a spare carriage on its own, order a carriage-only code and match its pairing letter to this rail; carriages of the same model interchange across rails and keep their smoothness and preload. Confirm the pairing code and current availability through an enquiry.
