Airtac LSH Linear Guide Block LSH30BK-HN-P-C-M6
The AirTAC LSH Linear Guide Block LSH30BK-HN-P-C-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-HN-P-C-M6
This code buys the moving half of a size 30 guide and nothing else: one AirTAC LSH30 square block in the standard length, precision accuracy, M6 fitting, and no rail whatsoever. The geometry inside is four ball rows on 45 degree X-pattern arc raceways, two contact points per ball - equal capacity vertical, lateral and upside down, plus enough self-alignment to forgive small errors in the mounting face. The rail beneath it, the LSH30 profile, measures 28 mm across.
Where this block earns its keep is moment: MR 0.66 kN.m in roll, MP and My 0.67 kN.m in pitch and yaw, on top of 37.4 kN dynamic and 55.0 kN static. Mount two blocks per rail and a cantilevered load is shared between two ball circuits, which is the standard cure for tipping along the travel. The pairing letter on this carriage is C; your rail must show the same letter for the rated preload and precision grade to hold.

Where the Airtac LSH Linear Guide Block LSH30BK-HN-P-C-M6 Is Used
Tapping unit Z-slide
A self-reversing tapping head hung off a short Z-slide loads the carriage in pitch; the 0.67 kN.m pitch figure, not the 37.4 kN load rating, is what sizes the block for the job.
Lens cell assembly press
An optical bench press that seats lenses into cells needs the ram held square; this block's 0.67 kN.m yaw rating and self-aligning ball pattern keep the tool face true to the seat.
Carton diverter gate
A pusher gate that diverts cartons between two conveyor lanes slides on this block; equal capacity in all four directions absorbs the side thrust at each end of the stroke.
Is the Airtac LSH Linear Guide Block LSH30BK-HN-P-C-M6 the Right Guide?
Size 30 earns its place through moment: MR 0.66 kN.m here against 0.44 kN.m for LSH25 standard, about 50 percent more for one size of part, and the long LSH30 carriage lifts roll moment further to 0.88 kN.m if the standard length falls short. Downward, if the envelope is tight and the load modest, LRM is the small-footprint option - we confirm its unrated loads by enquiry. Across, if the travel is short and you need crossed-roller rigidity over long recirculating travel, check LGC instead. When ordering, tick off: carriage-only form, size set by load AND moment, square style and standard length, number of blocks and rail length for a full set, accuracy and preload plus the installation tolerance they cost you, grease fitting, and the pairing letter that ties block to 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-HN-P-C-M6 FAQ
The catalogue numbers for this LSH30 standard-length carriage are C 37.4 kN dynamic, C0 55.0 kN static, moments MR 0.66 / MP 0.67 / My 0.67 kN.m, precision-grade parallelism of 3-21 um, M8 rail screws torqued to 3040 / 2010 / 1470 N.cm on steel, cast iron and aluminium, and a grease charge of 5.4 cm3 with 1.7 cm3 top-ups every 100 km of travel or 3 to 6 months.
A single carriage, nothing else: no rail, no mounting screws, no bolt caps. The LSH system pairs blocks to rails by letter, and this carriage is code C. A C-block on a C-rail keeps its precision grade and factory preload; a C-block on any other letter will not. Replacement buyers should quote the code printed or stamped on the original part, or the full model number of the set it came from.
