Airtac LSH Linear Guide Rail LSH30BK-F1L-N-C-M6
The AirTAC Airtac LSH Linear Guide Rail LSH30BK-F1L-N-C-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 LSH30BK-F1L-N-C-M6
One AirTAC LSH30BK-F1L carriage, pairing code C, normal accuracy - and nothing else, because the RLX rail is ordered separately. This long flange block rides the 28 mm wide LSH30 profile rail on four ball rows angled at 45 degrees; each ball touches its raceway twice, giving balanced capacity up, down and sideways plus a measure of self-alignment on imperfect mounting faces.
The block arrives pre-filled with Mobilux EP2 - 7.2 cm3 first charge for this long LSH30 carriage, 2.2 cm3 per top-up - and the M6 fitting takes the size-30 grease family. Budget for re-greasing every 100 km of travel or every 3 to 6 months, whichever comes first; a 500 mm stroke running 30 cycles a minute covers that distance in roughly six days, so the calendar rarely binds first. Ratings per block: 45.7 kN dynamic, 73.1 kN static.

Where the Airtac LSH Linear Guide Rail LSH30BK-F1L-N-C-M6 Is Used
Bottling line gate actuator guide
A filler's bottle-diverter gate cycles millions of short strokes; topping up through the M6 fitting every 100 km - a distance reached in days at high cycle rates - keeps the 45.7 kN-rated carriage turning smoothly through humid, sticky conditions.
Panel-saw fence carriage service
Sawdust is the enemy of a ball circuit; when the old block starts to notch, fit this long F1 carriage, drive the rail's bolt caps fully home so swarf stays out, and stroke it three carriage-lengths after greasing to distribute the new film.
PCB test fixture press head
A fixture that presses probe boards hundreds of times a shift needs even, quiet travel; the long body's 73.1 kN static rating shrugs off press-in shock, and the code-C block drops onto the existing LSH30 rail without touching the frame.
Is the Airtac LSH Linear Guide Rail LSH30BK-F1L-N-C-M6 the Right Guide?
Choose by duty: for light loads in a compact envelope, step down to LRM (we confirm its unpublished ratings case by case); for short strokes needing crossed-roller rigidity, cross over to LGC; stay with this LSH30 long carriage when travel is long and the moment arm is real. A checklist covers the rest: carriage-only form, size 30 checked against both load and moment, F1 flange with long body, accuracy N, the M6 fitting for grease, and pairing code C. If your old block ran dry, a re-grease schedule of 100 km or 3 to 6 months - with at least three carriage-lengths of stroking after charging to spread the film evenly - brings back smooth travel.
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 LSH30BK-F1L-N-C-M6 FAQ
Per carriage: dynamic rating C 45.7 kN, static rating C0 73.1 kN, static moment limits 0.88 kN.m MR, 0.91 kN.m MP and 0.91 kN.m My. Accuracy is normal grade, with running parallelism of 12-37 um across the rail length bands. The mating LSH30 rail mounts on M8 screws at 3040 / 2010 / 1470 N.cm (steel / cast iron / aluminium). Lubrication: 7.2 cm3 first charge, 2.2 cm3 top-up, Mobilux EP2 or equivalent, refreshed every 100 km or 3 to 6 months.
It is not. The box holds one LSH30BK-F1L long top-flange carriage - no rail, no screws, no bolt caps. The letter C in the code is the pairing key: order an LSH30 RLX rail bearing the same C and the two parts will match; a different letter means they will not.
