Airtac LSH Linear Guide Rail LSH30BK-HN-N-B-M6
The AirTAC Airtac LSH Linear Guide Rail LSH30BK-HN-N-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-HN-N-B-M6
This listing is the carriage half of an AirTAC LSH30 guide: one square-type block in the standard length, normal accuracy grade, fitted with an M6 grease nipple and carrying the pairing letter B. NO RAIL IS INCLUDED - complete the axis by ordering an LSH30 rail under the same B code. The block rolls on four rows of recirculating balls seated in 45 degree arc raceways with two contact points per ball, so it carries load equally up, down and sideways and absorbs slight mounting-surface error inside the carriage instead of binding. Size 30 runs on a 28 mm wide rail - not 30 mm - so lay out the datum shoulders to 28 mm before drilling.
Per carriage the catalogue gives 37.4 kN basic dynamic load C, 55.0 kN static C0 and moment ratings of 0.66 / 0.67 / 0.67 kN.m for MR / MP / My. Note that C0 sits only about 47 percent above C: the static margin is not the runaway number some buyers assume, and it is C that governs travel life. As a spare part this block costs roughly a quarter of a complete LSH30 set, so when the rail still runs true a carriage swap is usually the economical repair.

Where the Airtac LSH Linear Guide Rail LSH30BK-HN-N-B-M6 Is Used
Carton palletiser pusher arm
Swap the worn square block under the layer-push plate of a palletising cell; the B letter must match the LSH30 rail already bolted to the pusher beam.
Bottling line guide rail
Re-block the bottle-diverter slide on a filling conveyor where washdown has stripped the original grease; the M6 nipple takes a standard grease gun coupler.
Nesting router Y-axis rebuild
Refresh the Y-axis of an MDF nesting table by replacing seized blocks one at a time, leaving the long 28 mm rail undisturbed on its M8 screws.
Is the Airtac LSH Linear Guide Rail LSH30BK-HN-N-B-M6 the Right Guide?
Before ordering, settle the form: a full set if the rail is scored or missing, this carriage alone if the rail is sound and you know the pairing letter. Size the part on moment as well as load - MR is 0.66 kN.m for the standard block and 0.88 kN.m with the long L carriage, a 33 percent gain that often decides a cantilevered duty where C climbs only around 22 percent. Step down to AirTAC LRM when the envelope is tight and the duty is light (its load ratings are not published, so we confirm them by RFQ), and step across to LGC when travel is short and you want crossed-roller rigidity rather than long recirculating runs. Order checklist: form, size checked against load and moment, square versus flange body, standard versus long length, carriage count and rail length, N/H/P accuracy, preload with its installation cost, M6-family fitting, and the pairing letter for a like-for-like swap.
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-HN-N-B-M6 FAQ
Per carriage in standard length: basic dynamic load C 37.4 kN, basic static load C0 55.0 kN, allowable static moments MR 0.66, MP 0.67 and My 0.67 kN.m. Accuracy grade N gives a running parallelism band of 12-37 um depending on rail length. Mount the rail with M8 screws torqued to 3040 N.cm in steel, 2010 in cast iron or 1470 in aluminium. Grease charge is 5.4 cm3 of Mobilux EP2 or equivalent, topped up with 1.7 cm3 every 100 km of travel or every 3 to 6 months.
No. This SKU is the carriage only - there is no rail, no mounting screws and no bolt caps, and the code carries no preload position. The final B is the pairing code: the block runs correctly only on an LSH30 rail whose code ends in the same letter, so read the letter off the original part or its delivery note before ordering.
