Airtac LSH Linear Guide Rail LSH30BK-F1N-N-C-M6
The AirTAC Airtac LSH Linear Guide Rail LSH30BK-F1N-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-F1N-N-C-M6
Pairing code C marks this AirTAC LSH30 replacement carriage - one top-flange block, size 30, standard length, normal accuracy, with an M6 grease nipple. This is a carriage-only sale: the 28 mm profile rail it runs on is NOT part of the package and must be bought separately under an RLX code or a complete-set code. Balls recirculate through four rows of X-shaped 45 degree raceways, giving the block identical capacity in every direction plus enough self-alignment to forgive small datum errors within the catalogue's limits.
The standard-length size 30 block is rated 37.4 kN dynamic and 55.0 kN static, with allowable moments of 0.66 kN.m in the rolling direction and 0.67 kN.m in both tipping directions. For a cantilevered load the moment number usually picks the size, not C: the long carriage raises MR about 30 percent (0.66 to 0.88 kN.m) while dynamic rises only about 22 percent, so overhung tools and spindles gain more from the long body than from raw load.

Where the Airtac LSH Linear Guide Rail LSH30BK-F1N-N-C-M6 Is Used
Machining-centre conveyor slide
The indexing slide that carries swarf out of a vertical machining centre runs continuously and wears its blocks first; a single F1 carriage with matching pairing letter C brings the motion back without touching the rail alignment.
Welding-table clamp slide
Fixture clamps that stroke across a profile rail on a welding table see impact loads at every clamp cycle; bolting this top-flange block down onto the existing carriage pad restores the running clearance the clamp was set up with.
Solar laminate inspection gantry
A camera carrier traversing above laminated panels needs repeatable, play-free travel; replacing a fatigued size 30 block - pairing code C - keeps the lens at its calibrated height without re-shimming the whole gantry.
Is the Airtac LSH Linear Guide Rail LSH30BK-F1N-N-C-M6 the Right Guide?
Size on both axes of duty: if the load is light and space is tight, LRM is the compact alternative, but its ratings are unpublished and must be confirmed case by case; if travel is short and you need crossed-roller stiffness rather than long recirculating runs, LGC fits better. Within LSH, a second carriage on the same rail addresses tipping along the travel, while a size step up or a longer block addresses moment across it.
Before ordering, check off: carriage-only form (no rail in the box), pairing code C shared with your rail, size 30 verified against load and moment, F1 top-flange pattern and standard length, accuracy N, no preload written into this carriage code (preload is selected only when a matched complete set is specified), and the M6 fitting suited to sizes 20 through 35.
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-F1N-N-C-M6 FAQ
Dynamic rating 37.4 kN, static 55.0 kN; moments 0.66 / 0.67 / 0.67 kN.m for MR, MP and My. Running parallelism for grade N spans 12 to 37 um by rail length. Fix the rail with M8 screws torqued to 3040, 2010 or 1470 N.cm on steel, cast iron or aluminium. Grease first charge is 5.4 cm3 per block with 1.7 cm3 top-ups, on a 100 km or 3-to-6-month cycle.
The package holds one F1 top-flange carriage and nothing else - no rail, no bolt caps, no mounting screws. The letter C here is the pairing code that ties carriage to rail; it is not preload C and not accuracy P. Preload is only written into complete-set order codes, and accuracy appears separately as the N in this part number. To match, your existing rail must carry the same pairing letter.
