Airtac LSH Linear Guide Rail LSH15RLX1180-S20-H-E
The AirTAC Airtac LSH Linear Guide Rail LSH15RLX1180-S20-H-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 LSH15RLX1180-S20-H-E
High accuracy is the whole point of this part: LSH15RLX1180-S20-H-E is a bare 1180 mm profile rail of 15 mm width, S20 end offset, ground to the H grade and carrying pairing code E. It arrives without any carriage - the recirculating block, its load rating and its lubrication are separate line items. On the H grade the running parallelism tightens to a 7-28 um band, roughly half the drift you would accept from the normal grade.
Over a baseline this long, that figure earns its keep: an 1180 mm straight edge holding 7-28 um keeps a travelling camera or probe from sweeping in and out of its working window. The cut sits comfortably inside the 4040 mm maximum length for size 15, and M4 fixing screws pulled down to 412 N.cm on steel - 274 on cast iron, 206 on aluminium - determine how much of the ground straightness reaches the machine.

Where the Airtac LSH Linear Guide Rail LSH15RLX1180-S20-H-E Is Used
Coordinate measuring fixture rail
A touch-probe slide on a small CMM-style fixture runs on this H-grade rail, where a 7-28 um parallelism band keeps probe repeatability inside the tolerance stack.
PCB AOI camera rail
Automated optical inspection of circuit boards needs the camera bar to track dead straight; the H grade holds the lens line across an 1180 mm panel scanner.
Flying laser marking bridge
A marking bridge sweeping small parts at pace runs on this rail; straightness at H grade keeps spot placement consistent along the full 1180 mm stroke.
Is the Airtac LSH Linear Guide Rail LSH15RLX1180-S20-H-E the Right Guide?
Choose the H grade rail when the machine specification demands straightness that the N grade cannot sign off - metrology fixtures, optical benches, inspection gantries. The trade is cost, not fit: width, section and pairing code are identical to the normal-grade 15 mm rail, so an existing E carriage runs on either. Downshift to LRM when the load is trivial and space scarce (its ratings are unpublished, so we verify them for you); if the moment governs, one step to LSH25 or a long LSH15 carriage adds moment capacity faster than extra blocks; for short strokes wanting roller stiffness, LGC is the cross-over. Confirm before ordering: rail-only form, 15 mm true width, 1180 mm length, S20 offset, H grade, and the code E read from the carriage you intend to run.
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 LSH15RLX1180-S20-H-E FAQ
H grade running parallelism spans 7-28 um over the length. Fixing is by M4 screws torqued to 412 N.cm on steel, 274 N.cm on cast iron or 206 N.cm on aluminium, seating into H 3.5, H1 3 and H2 4 mm shoulders with a maximum 0.5 mm corner fillet. The 1180 mm length sits well under the 4040 mm maximum for size 15. No load figures appear on this page: dynamic and static ratings are properties of the carriage, not of the track.
The box holds one 1180 mm LSH15 rail at high accuracy grade, with bolt caps for the M4 holes - no carriage of any kind. To pair it, take the pairing letter from the carriage you plan to use; both parts must read E. Any LSH15 E-coded block will run on this rail and retain its preload and rated accuracy, an interchangeability that applies within the LSH family only, never across other makers' rails. Seat the supplied caps flush with a flat plate and a plastic mallet before running the axis.
