Airtac LSH Linear Guide Rail LSH15RLX4000-P-E
The AirTAC Airtac LSH Linear Guide Rail LSH15RLX4000-P-E 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.

About the Airtac LSH Linear Guide Rail LSH15RLX4000-P-E
This code describes a precision-grade rail and nothing else: LSH15RLX4000-P-E supplies one 4000 mm LSH15 profile rail at accuracy grade P, with no carriage in the box and no preload of its own. A rail alone carries no load rating - that figure belongs to the carriage - so plan the build around the LSH15 carriage you will pair to it through the shared matching letter E. The rail width is 15 mm, matching the size code on this smallest LSH size, and the hardened raceways accept the four rows of balls of the mating carriage at 45 degrees, the pair then self-aligning within the allowable error limits.
Grade P is the tightest of the three LSH accuracy grades, with a running parallelism band of 3-21 um against 12-37 um for normal grade. The 4000 mm cut leaves only 40 mm of headroom under the 4040 mm size 15 maximum, so check the machine bed before ordering: straightness over a run this long is only meaningful if the mounting face is flat, the shoulder corner radius stays at or below 0.5 mm, and the M4 screws are drawn down progressively to 412 / 274 / 206 N.cm on steel / cast iron / aluminium.

Where the Airtac LSH Linear Guide Rail LSH15RLX4000-P-E Is Used
Photonics lab translation stage
A precision-grade rail with a 3-21 um parallelism band suits laser alignment benches, where beam drift over a 4 m travel must stay within tight optical tolerances.
Rebuilding a long measuring beam
When a 4 m inspection beam or edge-guide assembly is rebuilt, fitting a P-grade rail first re-establishes straightness before new carriages and sensors go on.
Stage upgrade in semiconductor test equipment
Integrators refreshing a wafer-handling or test stage order precision rail on its own so high-accuracy carriages can be paired onto freshly verified datum rails.
Is the Airtac LSH Linear Guide Rail LSH15RLX4000-P-E the Right Guide?
A rail this long is only as accurate as its mounting face, so before paying for grade P confirm the bed is flat and the M4 fixing holes are machined to the shoulder limits for size 15. If the duty turns out light and the envelope tight, AirTAC LRM may serve - its load ratings are not published, so we verify them for your case. If moment capacity is the binding constraint, move up a size or specify a long carriage on the pairing. For short travel where crossed-roller stiffness beats recirculating smoothness, LGC fits better than any LSH grade. Order checklist: rail-only form, 4000 mm cut, accuracy grade P, top-lock mounting, and pairing code E shared with the intended LSH15 carriage.
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 LSH15RLX4000-P-E FAQ
Rail-only, so no load ratings or grease data - the carriage owns those. Its own numbers: 4000 mm cut length, 40 mm under the 4040 mm maximum for size 15, 15 mm true rail width, precision grade with a running parallelism band of 3-21 um across the grade's length range, M4 screws torqued to 412 N.cm (steel), 274 N.cm (cast iron), 206 N.cm (aluminium), and a maximum mounting-shoulder corner radius of 0.5 mm.
No. The code is rail only: one 4000 mm precision-grade profile rail, and no carriage is included. A rail by itself has no load rating, no preload and no lubrication quantity. Buy an LSH15 carriage whose pairing code is also E, or order a complete LSH15 set if you want rail and carriage matched from the start - either way, read the letter off the part you are replacing first.
