Airtac LSH Linear Guide Rail LSH30BK-HN-N-C-M6
The AirTAC Airtac LSH Linear Guide Rail LSH30BK-HN-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-HN-N-C-M6
AirTAC part LSH30BK-HN-N-C-M6 is a single square carriage, standard length, normal (N) accuracy, with a side M6 lubrication port, sold on its own: the rail is NOT part of the deal and must be sourced separately under the same C pairing letter. Inside, four ball rows run in opposed 45 degree arc grooves; because each ball touches at two points, the carriage takes a moment about any axis and swallows small flatness errors in the mounting face rather than jamming. The size code says 30, but the rail it mates with is 28 mm wide - worth checking against an existing machine drawing.
Ratings per block: C 37.4 kN, C0 55.0 kN, moments 0.66 kN.m (MR) and 0.67 kN.m (MP and My). One size down, LSH25, manages only 0.44 kN.m MR - this block carries about 50 percent more overturning moment for a single size step, which is why one well-placed LSH30 carriage often beats adding a second smaller block. Interchangeability helps the buyer too: any LSH30 carriage fits any LSH30 rail of the same model and keeps its running smoothness, accuracy grade and internal preload.

Where the Airtac LSH Linear Guide Rail LSH30BK-HN-N-C-M6 Is Used
Vision inspection re-block
Replace the carriage under a camera stage on a PCB inspection machine, where N-grade accuracy and the self-aligning four-row geometry tolerate slight table imperfection.
Autosampler X-bridge
Fit as a spare for the sample-plate bridge of a laboratory autosampler - light loads, but the moment from the offset probe arm suits the 0.66 kN.m MR rating.
Tool-changer magazine slide
Renew the guide block that carries the swing-arm magazine on a machining centre; a single block handles the offset weight without adding a second rail.
Is the Airtac LSH Linear Guide Rail LSH30BK-HN-N-C-M6 the Right Guide?
Work the decision in three directions. Down: if loads are modest and space is scarce, LRM is the lighter family, but AirTAC publishes no load ratings for it, so we will confirm figures for your duty on request. Across: where travel is short and stiffness matters more than long life, LGC crossed-roller guides give a rigid alternative. Up: for cantilever or offset loads, either take the long LSH30 carriage or go a size larger - moment capacity, not C, usually sets the limit. Your checklist: set versus carriage-only form, size against both load and moment, body style (square here; F1 and F2 flanges exist), standard or long block, how many carriages per rail and rail length, N/H/P grade, preload and the tighter mounting tolerance it demands, grease fitting, and the pairing letter when replacing.
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-HN-N-C-M6 FAQ
You receive one square carriage with an M6 fitting and normal accuracy. No rail, no screws and no bolt caps come with it. The C is the pairing code - LSH30 rails carry the same letter and the two run as a matched pair, so a block ordered with the wrong letter will not seat properly on your rail. The code also holds no preload position; that selection exists only on complete sets.
Catalogue values per standard-length block: C 37.4 kN dynamic, C0 55.0 kN static, MR 0.66 kN.m, MP 0.67 kN.m, My 0.67 kN.m. Grade N parallelism runs 12-37 um depending on rail length. Fix the rail with M8 screws at 3040 / 2010 / 1470 N.cm for steel / cast iron / aluminium, keep the mounting-surface corner radius at or below 1 mm, and grease with 5.4 cm3 at fitting and 1.7 cm3 at each 100 km or 3 to 6 month service.
