Airtac LSH Linear Guide Rail LSH30BK-F1N-H-B-M6
The AirTAC Airtac LSH Linear Guide Rail LSH30BK-F1N-H-B-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-H-B-M6
This listing is the carriage alone: one LSH30BK-F1N-H-B-M6 top-flange block for the AirTAC LSH30 profile rail series. No rail is included, and no preload position exists in this code. Inside the block, four rows of balls circulate through X-shaped arc raceways cut at 45 degrees, each ball touching at two points, so capacity is equal radially, laterally and in moment, and slight mounting-surface error is absorbed within the block instead of showing up as bind. The size code says 30 but the true rail width is 28 mm - lay out the mating face from the datasheet, not the code.
Per block, the catalogue gives 37.4 kN basic dynamic load C, 55.0 kN static C0, and moments of 0.66 kN.m MR, 0.67 kN.m MP and 0.67 kN.m My. Because a spare carriage costs roughly a quarter of a complete set, swapping the block on a sound rail is usually the cheapest way back to a running axis - provided you order by the pairing code B, which the rail must share.

Where the Airtac LSH Linear Guide Rail LSH30BK-F1N-H-B-M6 Is Used
CNC router Z-axis rebuild
A light industrial router table with a worn size 30 block under the spindle plate gets a like-for-like F1 carriage swap on the existing 28 mm rail, restoring smooth travel for about a quarter of the cost of a full set.
Electronics transfer lift
A top-flange block carries the rising platen of a small PCB transfer unit, where load arrives from below, above and sideways in turn - the four-row 45 degree geometry holds rating in every direction.
Vision station camera retrofit
Converting a PCB inspection camera travel from sliding bushings to a grade H recirculating-ball carriage on a pairing code B rail steadies the image without redesigning the base plate.
Is the Airtac LSH Linear Guide Rail LSH30BK-F1N-H-B-M6 the Right Guide?
Form comes first: if you are building a new axis, a complete LSH30 set with rail cut to length is the simpler order; this listing exists for replacing or upgrading the block on a rail you already have. The match checklist: same series and size, F1 top-flange drilling, standard length, grade H, M6 fitting, and the pairing code B shared with the rail. Size on load and moment together - 37.4 kN C and 0.66 kN.m MR answer different questions. If the duty is light and space tight, LRM steps down, though its load ratings are unpublished and we confirm them per job. If moment governs, take the long F1L block (45.7 kN, 0.88 kN.m) or LSH35, which we supply to order. For short travel where crossed-roller stiffness matters more than long recirculating runs, LGC is the cross-over pick.
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-H-B-M6 FAQ
Per carriage: basic dynamic load C 37.4 kN, static C0 55.0 kN, moments MR 0.66, MP 0.67 and My 0.67 kN.m. Grade H running parallelism spans 7-28 um depending on rail length. Rail mounting screws are M8, torqued to 3040 N.cm on steel, 2010 on cast iron, 1470 on aluminium. Grease is Mobilux EP2 or equivalent: 5.4 cm3 first charge, 1.7 cm3 top-up, repeated every 100 km of travel or every 3 to 6 months.
No. The box holds one top-flange carriage only - the BK in the code means block, not set. The trailing letter B is the pairing code, and the LSH30 rail you mount it on must carry the same letter. Within the LSH model range, any carriage fits any rail of that model and keeps its smoothness, preload and accuracy.
