The AirTAC Airtac LSH Linear Guide Rail LSH15HN2X200S8CH-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.
LSH15HN2X200S8CH-M4 is a complete size 15 linear guide ordered with medium preload C: a 200 mm rail with an 8 mm end-hole offset, carrying two square standard-length carriages in one set. Four rows of balls recirculate through X-shaped raceways set at 45 degrees and meet each raceway at two points, so capacity is equal in every direction; the C preload removes internal clearance, stiffening the blocks under reversing loads and vibration. The rail is 15 mm wide.
Per carriage the ratings are 11.3 kN dynamic, 17.9 kN static and 0.12 kN.m on each moment axis, unchanged by preload. What preload changes is the installation budget: with grade H running parallelism at 7-28 um, the mounting surface must now hold height error S to 35 um and parallelism error P to 13 um per 500 mm of rail spacing, versus 130 and 25 um for a set without preload. That is the price of the stiffer feel, and it pays off only where the machining can back it up.

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.
A light engraving spindle traverses 200 mm over the workpiece; medium preload damps the play that would otherwise show as chatter on the surface at each direction change.
A shuttle carries small electronic modules between load and test stations on a 200 mm stroke; preload C holds the payload steady through the acceleration reversals of a fast cycle.
The test probe advances onto the spring and retracts; with no clearance left in the ball circuit, the measured deflection is not masked by guide play.
Preload does not raise the catalogue load ratings, so size on the same basis as ever: 0.12 kN.m of moment per block means a cantilevered tool often forces a step up to LSH20 (MR 0.27 kN.m) rather than a heavier preload grade. If the duty is light and space scarce, LRM is the smaller series, but its load ratings are not published and we would confirm them; if the travel is short and crossed-roller rigidity is what you need, LGC serves that brief instead.
Before ordering, confirm: complete-set form, size by load and moment, square standard carriages, two per rail, 200 mm length and 8 mm end offset, grade H accuracy, preload C with its tighter 35 um height tolerance, and the M4 grease fitting.
Quick checklist
Per standard square carriage: 11.3 kN basic dynamic C, 17.9 kN basic static C0 and 0.12 kN.m allowable static moment in each of MR, MP and My. Grade H running parallelism: 7-28 um by rail-length band. Fixing: M4 screws torqued to 412 N.cm (steel), 274 N.cm (cast iron) or 206 N.cm (aluminium). Lubrication: 0.9 cm3 Mobilux EP2 first charge, 0.3 cm3 top-up through the M4 fitting, repeated every 100 km of travel or every 3 to 6 months.
It removes internal clearance but tightens the installation window sharply: at 500 mm rail spacing the catalogue allows only 13 um of parallelism error P and 35 um of height error S, against 25 and 130 um for a preload-A set, scaled to your actual spacing. The rail must be pulled squarely onto its datum face and fully torqued, and the corner radius at the shoulder must stay within 0.5 mm. If your base plate cannot be machined that accurately, order the AN version of the same set instead.
