Airtac LSH Linear Guide Rail LSH30RLX2525-S22.5-N-E
The AirTAC Airtac LSH Linear Guide Rail LSH30RLX2525-S22.5-N-E is a standard-type profile linear guide on a 28 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 LSH30RLX2525-S22.5-N-E
This listing is a rail alone: one LSH size 30 profile rail, 2525 mm long, accuracy grade N, pairing code E, top-lock mounting, and explicitly no carriage, no preload and no grease fitting - a rail has none of those. Buyers choose the part form when carriages are already in hand or when a machine frame needs a cut length that standard sets do not offer. The rail surface is the hardened raceway for the carriage balls; the catalogue does not state the base material, so confirm anything material-related through an RFQ before specifying welding or coating.
At 2525 mm this rail uses about 63 percent of the 4030 mm maximum length for size 30, so a long axis can run as a single piece with no joint in the middle. The S22.5 end-hole offset places the first and last mounting holes just 22.5 mm from the rail ends - the tightest end overhang of the common offsets in this size - useful where end stops or machine plates crowd the stroke ends. Grade N parallelism for the size falls between 12 and 37 um over the finished length.

Where the Airtac LSH Linear Guide Rail LSH30RLX2525-S22.5-N-E Is Used
Tray conveyor guide run
A 2.5 m tray conveyor in a food plant carries its pusher gantry on this rail; the single-piece length avoids a joint under the washdown zone where a splice would trap residue.
Beam saw retrofit
Retrofitting a beam saw cross-cut carriage, the fitter reuses sound pairing-E blocks on a fresh 2525 mm rail instead of buying a whole guide, cutting the repair to roughly a quarter of the set price.
Modular fixture table
A modular welding fixture table takes this rail as the linear datum for a removable stop module; the small 22.5 mm end offset lets the module sit almost flush with the table edge.
Is the Airtac LSH Linear Guide Rail LSH30RLX2525-S22.5-N-E the Right Guide?
Pairing is the first check: this rail accepts only LSH30 carriages with pairing code E, and the letter is marked with the part, so read it off the old carriage before ordering a replacement rail. If the duty is lighter than the ratings suggest, LRM is the step down - we confirm its unpublished load figures against your application. If moment governs, step up: a long LSH30 carriage raises MR to 0.88 kN.m and LSH35 reaches 1.05 kN.m. Short-travel work wanting crossed-roller rigidity is LGC territory. Then confirm the rest: form (rail only here); size by load and moment together; carriage style, length and count; rail length; accuracy and preload, remembering that medium preload on this size cuts the allowable height error from 170 to 90 um; the grease fitting lives on the carriage; and the pairing code.
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 LSH30RLX2525-S22.5-N-E FAQ
Width 28 mm (true), length 2525 mm against a 4030 mm maximum for size 30, grade N parallelism 12-37 um, S22.5 end-hole offset, top-lock mounting. Fasten with M8 screws at 3040 N.cm (steel), 2010 N.cm (cast iron) or 1470 N.cm (aluminium); shoulders H 6.5, H1 5, H2 5 mm; corner radius 1 mm maximum. A rail carries no dynamic or static rating, no moment rating, no preload and no grease charge - read all of those from the carriage that runs on it.
The box holds one 2525 mm rail and its bolt caps - no carriage. Matching works by pairing code E: the carriage and the rail must both carry E for the rated smoothness, preload and accuracy. Carriage-only SKUs list the same letter in their code, so check it before buying a replacement block; a carriage with a different letter on this rail falls outside the guarantee. If the code is unreadable, quote the full SKU from your old part and we will identify the match.
