Airtac LSH Linear Guide Rail LSH30BK-F1L-N-B-M6
The AirTAC Airtac LSH Linear Guide Rail LSH30BK-F1L-N-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-F1L-N-B-M6
This listing is the carriage only - a single AirTAC LSH30BK-F1L long top-flange block for the LSH30 linear guide family. No rail is supplied with it. Inside, four rows of recirculating balls run in X-arranged arc raceways set at 45 degrees, two contact points per ball, so the block carries loads and overturning moments equally in all four directions and absorbs slight mounting-surface error instead of binding. Note that the true rail width for LSH30 is 28 mm, not 30.
The long body raises the ratings over a standard LSH30 carriage: 45.7 kN dynamic C and 73.1 kN static C0 per block, with moment limits of 0.88 kN.m MR, 0.91 kN.m MP and 0.91 kN.m My. The long body lifts MR about 33 percent over the standard carriage's 0.66 kN.m, which matters more than the 22 percent gain in C when the load hangs off a lever arm. Your rail must carry pairing code B.

Where the Airtac LSH Linear Guide Rail LSH30BK-F1L-N-B-M6 Is Used
CNC router gantry spindle plate
Swapping a worn standard block under a router's spindle mounting plate: the long F1 carriage's 0.88 kN.m MR absorbs the overturning moment a top-mounted cutting head creates, and bolting from above suits an aluminium gantry plate.
Palletiser lift-column slide
A case palletiser's vertical guide column takes the load offset of the clamp on every cycle; long top-flange carriages on the 28 mm LSH30 rail resist tipping along the travel, and a spare block keeps the line moving after a failure.
Optical inspection microscope stage
Upgrading the X-axis of a benchtop inspection station: normal-grade accuracy keeps running parallelism inside 12-37 um, enough for camera-based measurement, and the top flange bolts the stage plate down cleanly.
Is the Airtac LSH Linear Guide Rail LSH30BK-F1L-N-B-M6 the Right Guide?
Size the guide by load and moment together. If the duty is light and space is tight, the smaller LRM series may suffice, but its load ratings are not published, so ask us to confirm them against your duty cycle. If the moment governs - a cantilevered or overhung load - this long carriage is already the right move within LSH30, lifting MR 33 percent over the standard block; the next lever is stepping up to LSH35, which is available to order. For short travel where crossed-roller stiffness matters more than long recirculating runs, LGC is the alternative. Before ordering, tick off: form (carriage only), size by load AND moment, F1 top flange and L length, accuracy grade, grease fitting M6, and pairing code B to match your rail.
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-B-M6 FAQ
Per block: basic dynamic load C 45.7 kN, basic static C0 73.1 kN, allowable static moments MR 0.88, MP 0.91 and My 0.91 kN.m. Running parallelism at normal accuracy is 12-37 um depending on rail length. The matched rail uses M8 screws torqued to 3040 / 2010 / 1470 N.cm in steel / cast iron / aluminium. This long carriage takes 7.2 cm3 of grease first charge and 2.2 cm3 per top-up (Mobilux EP2 or equivalent), renewed every 100 km of travel or every 3 to 6 months.
No - this is the carriage only; the LSH30 RLX rail is a separate part. Rails and carriages are matched by a pairing code, the letter in this SKU: B. Buy a rail with the same code and the fit, running class and accuracy carry over; a rail with any other letter will not pair with it.
