Airtac LSH Linear Guide Block LSH30BK-HL-P-D-M6
The AirTAC LSH Linear Guide Block LSH30BK-HL-P-D-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-HL-P-D-M6
Ordered as LSH30BK-HL-P-D-M6, you receive one long square carriage for LSH30 at precision grade, with an M6 lubrication nipple and the D pairing code - and no rail. The X-pattern ball arrangement, four rows contacting arc raceways at 45 degrees, is what lets a single block take downward, side and overturn load alike, while self-alignment forgives minor machining error on the mounting face. The 30 in the code is the size, not the rail width; the rail is 28 mm wide.
Going long rather than standard is a moment decision: MR rises from 0.66 to 0.88 kN.m, about 33 percent, while dynamic C goes from 37.4 to 45.7 kN, about 22 percent - so a cantilevered or offset head benefits more than a plain one. Per-carriage figures: C 45.7 kN, C0 73.1 kN, MR/MP/My 0.88/0.91/0.91 kN.m.

Where the Airtac LSH Linear Guide Block LSH30BK-HL-P-D-M6 Is Used
Machine-tending arm base
A job shop fitting a long carriage under an offset robot-tending arm on an LSH30 rail; the 0.88 kN.m roll moment rating carries the reach a standard block would not.
Laser head gantry
A signage fabricator replacing the carriage that carries an offset laser head on a cutting gantry, where overturn moment from the head decides block length.
Fast pick-and-place head
An electronics assembler renewing carriages on a high-speed pick-and-place gantry whose cantilevered placement head needs moment headroom at speed.
Is the Airtac LSH Linear Guide Block LSH30BK-HL-P-D-M6 the Right Guide?
Size for moment first when the load hangs off the block. This long carriage raises MR 33 percent over the standard LSH30 block as one part; a second carriage on the same rail instead attacks tipping along the travel. If your envelope is small and duty light, LRM is the step down - ratings unpublished, so we verify them with you. Short travel needing roller rigidity is LGC territory, and LSH35 is the one-part step up, available to order.
Ordering checklist: confirm the form (carriage only, rail not supplied), size by load AND moment, square long style, precision grade, M6 nipple, and the D pairing code on your existing rail. Pull the letter from the original rail's ordering string; a mismatched code will not pair, and a worn rail means a complete set is the smarter order.
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-HL-P-D-M6 FAQ
One long carriage carries C 45.7 kN, C0 73.1 kN, and moment limits MR 0.88, MP 0.91, My 0.91 kN.m. Running parallelism at P grade spans 3 to 21 um. Fastening calls for M8 screws at 3040 N.cm (steel), 2010 (cast iron) or 1470 (aluminium). Grease per block: 7.2 cm3 initial, 2.2 cm3 replenishment, every 100 km of running or every 3 to 6 months, whichever comes first.
One long square carriage with an M6 grease nipple at precision accuracy grade - no rail, no mounting screws, and no preload segment, since that belongs to the complete-set part number. The D in the code is the pairing letter that must match your rail's code, so read it from the rail's own ordering string before you buy. The block alone is the economical repair only while the rail is straight and its raceways are clean.
