Airtac LSH Linear Guide Block LSH30BK-F1N-P-E-M6
The AirTAC Airtac LSH Linear Guide Block LSH30BK-F1N-P-E-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 Block LSH30BK-F1N-P-E-M6
The BK in this AirTAC code means you are buying the block on its own: one LSH30 top-flange (F1) carriage, standard length, precision grade, with an M6 grease fitting and pairing letter E. No rail is included. Within the LSH series any carriage of a given model will run on any rail of that same model and keep its smoothness and accuracy - but the pairing letter still has to agree between the two, which is why E appears in this code and must appear on your rail. Size 30 carriages run on rails 28 mm wide.
Per carriage the catalogue lists 37.4 kN dynamic, 55.0 kN static and MR/MP/My moments of 0.66/0.67/0.67 kN.m. The M6 nipple belongs to the fitting family for sizes 20 to 35; on this flange carriage the side fitting may sit flush with, or stand slightly above, the top face, so lay any cover or bracket over the mounting position first and check for clash. Precision accuracy holds running parallelism within 3 to 21 um along the rail length.

Where the Airtac LSH Linear Guide Block LSH30BK-F1N-P-E-M6 Is Used
Robot gripper slide refit
Replacing the carriage under a robot gripper's servo slide: the F1 flange mounts from the top, keeping the underside of the 28 mm rail clear for the feed line.
Palletising pusher slide
A block replacement on the pusher slide of a palletiser running fast, short strokes, where precision grade keeps the push finger alignment stable across thousands of cycles per shift.
Parcel sorter divert slide
Renewing the divert-finger carriage on a parcel sorter, where the 3-21 um precision band keeps the finger tip tracking true so barcodes stay readable at line speed.
Is the Airtac LSH Linear Guide Block LSH30BK-F1N-P-E-M6 the Right Guide?
Know your code E and this is a fast way to revive a machine: carriage-only orders cost about a quarter of a full set, provided the rail itself is undamaged. For light loads in tight envelopes, step down to LRM - its ratings are unpublished, so we confirm them before quoting. If the cantilever moment at 0.66 kN.m is the limiter, choose the long LSH30L block at 0.88 kN.m MR or go up a size; adding a second block on the same rail instead addresses tipping along the travel. For short strokes wanting crossed-roller rigidity, cross to LGC. Checklist: carriage-only form, size 30 against load and moment, F1 flange, standard length, accuracy P, M6 fitting, and pairing code E off 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 Block LSH30BK-F1N-P-E-M6 FAQ
Load ratings per carriage: 37.4 kN dynamic (C) and 55.0 kN static (C0). Allowable moments: 0.66 kN.m MR, 0.67 kN.m MP, 0.67 kN.m My. Accuracy P runs at 3 to 21 um parallelism depending on rail length. The rail underneath is 28 mm wide and takes M8 mounting screws at up to 3040 N.cm in steel, 2010 in cast iron or 1470 in aluminium. Grease: 5.4 cm3 first charge, 1.7 cm3 top-up, every 100 km of travel or every 3 to 6 months.
No rail is included - this is a carriage-only order, and the BK code says so. You receive one precision-grade F1 top-flange block of standard length with an M6 fitting. Letter E is its pairing code, and it must match the letter on the LSH30RLX rail you run it on; a carriage and rail with different letters are not a factory-matched pair. If the marking is worn off, send us the stamped details from your rail and we will identify the code.
