Airtac LSH Linear Guide Rail LSH25RLX1080-S30-H-E
The AirTAC Airtac LSH Linear Guide Rail LSH25RLX1080-S30-H-E is a standard-type profile linear guide on a 23 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 LSH25RLX1080-S30-H-E
The LSH25RLX1080-S30-H-E delivers one 1080 mm length of LSH25 profile rail in high accuracy grade H, with the outermost mounting hole set 30 mm in from each rail end. That is all the box contains - there is no carriage, so the block's load ratings, preload and lubrication schedule are not quoted here. The rail is the fixed half of the guide: a hardened raceway track along which four rows of balls in the paired carriage circulate at 45 degree contact, giving equal capacity in every direction and absorbing slight mounting errors. Size 25 measures 23 mm true rail width - drill the seat from the datasheet, never from the code.
The 30 mm end offset, 10 mm deeper than the standard 20 mm, pushes the first bolt further inboard - useful when a stop, limit switch or carriage overrun must sit clear of the end holes. Grade H parallelism is 7-28 um; at 1080 mm nearly 3000 mm of headroom remains under the 4040 mm Lmax for size 25. M6 screws at 921 N.cm in cast iron (1370 in steel, 686 in aluminium) hold the grade only when the rail is seated hard against its datum.

Where the Airtac LSH Linear Guide Rail LSH25RLX1080-S30-H-E Is Used
Lens edging X-feed rebuild
An optical lab's lens edging machine feeds the blank on a short X-axis; a worn rail is swapped for this 1080 mm grade H length, restoring the 7-28 um straightness the grind quality depends on.
Dispensing module rail
A benchtop fluid dispensing robot's X-module takes this rail, with the 30 mm end offset leaving clean space at each end for the home sensor and hard stop.
Checking fixture slide
A production measurement fixture for machined housings slides its dial probe on a code E carriage over this rail; the fitter torques the M6 screws to 686 N.cm in the aluminium base.
Is the Airtac LSH Linear Guide Rail LSH25RLX1080-S30-H-E the Right Guide?
Start by asking whether LSH25 is even the right frame. Light duty in a tight envelope may suit the smaller LRM series - we confirm its load figures with you, because they are not published. Short travel with a premium on rigidity points to crossed-roller LGC instead. If LSH25 stands, check off: form (rail only on this page), the paired carriage sized on load AND moment, carriage style and length, number of carriages and rail length, accuracy and preload with their installation trade-off, the grease fitting on the carriage, and the pairing letter - both parts must be E. Replacing an old rail? Lift the code straight off the original rather than guessing.
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 LSH25RLX1080-S30-H-E FAQ
Length 1080 mm; accuracy grade H with 7-28 um running parallelism across the band; end holes 30 mm from each rail end; Lmax for size 25 is 4040 mm. Fixing is M6: 1370 N.cm in steel, 921 N.cm in cast iron, 686 N.cm in aluminium. Shoulders H 6.5, H1 5, H2 5 mm, corner radius max 1 mm. No load rating, preload or grease figure applies to the rail itself - those live on the carriage datasheet.
Exactly one thing: the 1080 mm grade H rail. No carriage is included and this is not a complete set. Each rail and carriage in the series carries a pairing letter - this one is E - and only parts sharing that letter are matched for accuracy and preload class. Order the carriage separately under an E-coded part number, or read the letter off your existing component before ordering a replacement.
