Airtac LSH Linear Guide Block LSH30BK-HN-P-D-M6
The AirTAC LSH Linear Guide Block LSH30BK-HN-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-HN-P-D-M6
LSH30BK-HN-P-D-M6 is the carriage element of the AirTAC LSH range, ordered on its own: square style, standard length, precision grade accuracy, M6 lubrication fitting. The box contains one block and no rail. Inside the block, four rows of balls recirculate through arc raceways set at 45 degrees in an X layout, two points of contact each, giving the same load rating in every direction and a self-aligning action that absorbs minor machining error in the mounting surface. Its rail, the LSH30 profile, is 28 mm wide.
Precision grade holds running parallelism to a 3-21 um band, the tightest the LSH series publishes, and this block keeps its grade when mated to a rail ordered to the same grade and the same pairing letter, D. Ratings are 37.4 kN dynamic, 55.0 kN static and 0.66-0.67 kN.m in the three moment axes per block. Mixed pairing letters are the classic ordering mistake; they will not preserve preload or accuracy.

Where the Airtac LSH Linear Guide Block LSH30BK-HN-P-D-M6 Is Used
Granite table laser scanner
A laser line scanner traversing a calibrated granite table holds beam registration over a metre of travel because precision grade keeps running parallelism inside 3-21 um.
Float-glass camera bar
A camera bar flying over float glass on the inspection line rides on this precision block, so pixel scale does not wander as the scan advances along the ribbon.
Desktop dispensing robot
A dispensing robot looping a 400 mm circuit at speed keeps path height constant on a precision-grade carriage - and at that duty the 100 km re-grease mark arrives fast, so fit the M6 nipple where it can be reached.
Is the Airtac LSH Linear Guide Block LSH30BK-HN-P-D-M6 the Right Guide?
Precision grade is the tightest LSH offers, and it changes how you must build around it: on a complete set at 500 mm rail spacing, medium preload cuts allowable parallelism error to 20 um and height error to 70 um for this size, figures that shrink in proportion to actual spacing. That is the trade to weigh before choosing preload when you later order the rail. If the application is lighter and the envelope smaller, step down to LRM and let us confirm its unpublished ratings; if travel is short and stiffness matters more than stroke, LGC's crossed rollers are the cross-check. Confirm before ordering: this is carriage only, size chosen on load and moment, square standard-length style, block count and rail length for a set, accuracy and preload grades, grease fitting, and the matching pairing code.
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-D-M6 FAQ
Yes. This LSH30 square standard carriage is rated 37.4 kN dynamic and 55.0 kN static per block, with moment limits of MR 0.66 kN.m, MP 0.67 kN.m and My 0.67 kN.m. Precision grade running parallelism spans 3-21 um depending on rail length. Mounting screws for the rail are M8, tightened to 3040 N.cm in steel, 2010 in cast iron, 1470 in aluminium. Grease: 5.4 cm3 first charge, 1.7 cm3 per top-up, interval 100 km of travel or 3 to 6 months.
It is a carriage only - there is no rail in the box and no way to mount it alone. To complete the axis you need an LSH30 rail ordered to the same precision grade and, critically, the same pairing letter, D in this case. The letter is AirTAC's way of guaranteeing that a given block and rail were lapped as a pair; cross-lettered parts lose their preload and accuracy. Quote the letter from your old carriage or existing rail when you enquire.
