Airtac LSH Linear Guide Rail LSH30BK-F2L-H-B-M6
The AirTAC Airtac LSH Linear Guide Rail LSH30BK-F2L-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-F2L-H-B-M6
This listing is the carriage only: one AirTAC LSH30 bottom-flange block, F2 style with the long body, high accuracy, M6 grease fitting and pairing code B. NO RAIL IS INCLUDED and this code contains no rail segment - order a mating LSH30 rail carrying the same pairing letter, or read the letter off the part you are replacing. The block runs on four rows of recirculating balls seated in X-shaped arc raceways cut at 45 degrees, two contact points per ball, so it carries equal load up, down and sideways and absorbs slight mounting-surface error inside itself instead of binding. Despite the 30 in the code, the rail it rides on is 28 mm wide.
Because the body is the long version, its moment ratings climb faster than its load ratings: dynamic rating goes from 37.4 kN on the standard block to 45.7 kN, about 22 percent, while MR rises from 0.66 to 0.88 kN.m, about 33 percent. Static rating is 73.1 kN. For a cantilevered or overhung load, MR is usually the figure that decides whether the block survives, so the long body earns its extra length there first.

Where the Airtac LSH Linear Guide Rail LSH30BK-F2L-H-B-M6 Is Used
Stone bridge saw cross-slide
A bridge saw trimming granite slabs carries its cutting head on a cantilevered arm, so MR decides block survival. Swapping in this long F2 body lifts moment capacity from 0.66 to 0.88 kN.m over the standard block.
Palletizer arm joint
End-of-arm tooling on a case palletizer tips the carriage outward on every lift. A long-body block with 0.88 kN.m MR and a bottom flange keeps the bolt line under the load path.
Aluminum-profile inspection gantry
When building a camera gantry from profile, bolting the F2 flange from below leaves the block's top face free for the camera bracket and cable chain.
Is the Airtac LSH Linear Guide Rail LSH30BK-F2L-H-B-M6 the Right Guide?
Work through the checklist in order. Form: this is a carriage only, so confirm you need a replacement block and not a complete set. Size: check load AND moment - if the duty is light and the envelope tight, LRM may do the job in a smaller footprint, though its load ratings are not published and we will confirm them with you; if MR governs and this long F2 body still falls short, stepping up a size buys more moment than adding another carriage. Travel character: for short strokes needing crossed-roller rigidity rather than long recirculating travel, ask about LGC instead. Then fix carriage style (F2 bottom flange here), length (long), count, rail length, accuracy grade (H), grease fitting (M6, correct for size 30) and, because you are buying a part, the pairing code - it must match the 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-F2L-H-B-M6 FAQ
Per carriage: basic dynamic load rating C 45.7 kN, basic static C0 73.1 kN, allowable static moments MR 0.88, MP 0.91, My 0.91 kN.m (long body; the standard LSH30 block is 37.4 kN, 55.0 kN and 0.66 / 0.67 / 0.67 kN.m). High accuracy grade running parallelism falls in a 7 to 28 um band across the rail-length range. The mating LSH30 rail is 28 mm wide and uses M8 mounting screws at 3040 N.cm in steel, 2010 in cast iron, 1470 in aluminium. Grease: first charge 7.2 cm3, top-up 2.2 cm3, re-grease every 100 km of travel or every 3 to 6 months.
No rail is included. The BK in the code marks this as a carriage only - one long F2 block, high accuracy, M6 fitting. There is no rail segment in the part number and no preload position either. AirTAC LSH carriages and rails carry a pairing letter, and this block must be fitted to an LSH30 rail of the same model bearing the letter B to preserve its smoothness, preload and accuracy. If you are replacing an old block, copy the letter from its code; if it is unreadable, send us the code and we will match it.
