The AirTAC Airtac LSH Linear Guide Rail LSH15HN1X1200S30AN-M4 is a standard-type profile linear guide on a 15 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.
LSH15HN1X1200S30AN-M4 is a complete linear guide set from AirTAC's LSH range: one square, standard-length (H, N) carriage supplied on a 1200 mm length of profile rail, with an M4 grease fitting on the carriage side. Size 15 runs on a rail that is genuinely 15 mm wide, so the code and the mounting width agree. Four rows of recirculating balls ride X-arranged arc raceways cut at 45 degrees, so the carriage carries load equally upward, downward and sideways, and small flatness or alignment faults in the mounting face are taken up inside the carriage rather than showing up as binding.
The single standard carriage is rated at 11.3 kN dynamic and 17.9 kN static, with a 0.12 kN.m static moment limit about each of MR, MP and My. Accuracy is normal grade, so running parallelism sits in the 12-37 um band for this rail length. At 1200 mm the rail uses well under half of the 4040 mm maximum for size 15, leaving room to lengthen the axis later. One carriage means any overhung load must respect that 0.12 kN.m moment along the travel; adding a second carriage on the same rail is the usual fix.

Rail and carriage(s) supplied together, matched as a set. If you are not sure which form you need, send us the machine or the original part number and we will confirm it before you order.
Carries a lightweight cutting head across a metre or more of travel. The 11.3 kN dynamic rating is generous for the head weight; keep an overhanging lens barrel within the 0.12 kN.m moment or add a second carriage.
A vision camera traverses 1.1 m across printed circuit boards on this rail. Normal-grade parallelism of 12-37 um is adequate for autofocus, and equal capacity in all four directions handles the reversals at each panel end.
A glue or solder-paste valve rides the carriage with its cable chain alongside. The M4 side fitting lets maintenance re-grease without disassembly - check the fitting does not stand proud enough to foul the chain.
Start from the duty, not the code. If the load is a few kilograms and the envelope is tight, LRM may do the job for less; its load ratings are not published, so we confirm suitability with you before you order. Where the travel is short and the priority is rigidity over run length, LGC crossed-roller guides are the stiffer choice. Stay on LSH15 when you want long recirculating travel at low friction. For heavier or overhung loads, check the 0.12 kN.m moment limit first - moving to a long carriage or up to LSH20 buys more moment capacity than a second small carriage does. Checklist before ordering: confirm the form (this is a complete set), size by both load and moment, carriage style and length, number of carriages and rail length, accuracy and preload against your installation tolerance, the grease fitting, and the pairing code if you are matching parts to an existing rail.
Quick checklist
Per standard-length carriage: dynamic rating C 11.3 kN, static rating C0 17.9 kN, and static moment ratings of 0.12 kN.m each about MR, MP and My. Normal-grade running parallelism falls between 12 and 37 um depending on rail length. Mount with M4 screws at 412 N.cm into steel, 274 N.cm into cast iron or 206 N.cm into aluminium. Each carriage ships with about 0.9 cm3 of Mobilux EP2; re-grease with 0.3 cm3 every 100 km of travel or every 3 to 6 months, whichever comes first.
With no preload this set is the most forgiving in the range: at 500 mm rail spacing you may allow 25 um of parallelism error and 130 um of height difference between rails, scaled to your actual spacing. Light preload B tightens that to 18 and 85 um, and medium C to 13 and 35 um - nearly four times stricter on height than this zero-preload version. Rigidity is bought at the cost of installation precision, and the self-aligning behaviour only absorbs errors within these limits, not unlimited ones.
