Airtac LSH Linear Guide Rail LSH25RLX880-S20-H-E
The AirTAC Airtac LSH Linear Guide Rail LSH25RLX880-S20-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 LSH25RLX880-S20-H-E
This is an 880 mm LSH25 profile rail supplied alone, ground to high (H) accuracy - one grade above normal - with the S20 end-hole offset. The order of the day is precision, not payload: a rail has no load rating of its own, and no carriage comes with it. The rail is 23 mm wide, a detail that matters when you machine the seat to a tight datum.
High grade tightens the running parallelism to the 7-28 um band, against 12-37 um for grade N - worthwhile when a carriage must track dead-true along nearly a metre of travel. The cut still leaves generous headroom below the 4040 mm Lmax for this size. Match your carriage by the E pairing code; a block with another letter will not carry the factory-matched running quality.

Where the Airtac LSH Linear Guide Rail LSH25RLX880-S20-H-E Is Used
Laboratory dosing stage
An analytical-instrument builder moves a sampling head across eight reagent stations on this 880 mm grade-H rail; the tighter parallelism band keeps the dosing nozzle height constant from station 1 to station 8.
Vision-inspection camera track
A factory QA cell slides its camera on a rail above a conveyor; at high grade the image stays in focus along the whole travel without re-focusing, and the 23 mm rail width fits the shallow extrusion frame.
Large-format 3D printer gantry
A wide-bed resin printer uses this rail as one gantry member; grade H parallelism keeps the build plate gap uniform edge to edge, which a normal-grade axis could not hold over 880 mm.
Is the Airtac LSH Linear Guide Rail LSH25RLX880-S20-H-E the Right Guide?
Pick this high-grade rail when the axis feeds a measuring device, an optical path or a cutting head where a few tens of microns of wander are visible in the result. If your duty is lighter and more compact, the LRM family steps down - though its load ratings are not published, so we verify them for you. For short strokes needing crossed-roller rigidity, step across to LGC instead of lengthening recirculating travel.
Order with this checklist: form is rail only (carriage separate), size set by load AND moment of the chosen block, carriage style and length, count per axis, accuracy grade H here with a suitable preload on the block - remembering tighter preload narrows the allowable mounting error - grease fitting, and the pairing code E when replacing a part. Confirm unstated dimensions from the datasheet via RFQ.
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 LSH25RLX880-S20-H-E FAQ
Accuracy H: running parallelism 7-28 um across the length. Fixing: M6 screws torqued to 1370 N.cm on steel, 921 on cast iron, 686 on aluminium. Shoulder heights H 6.5 mm, H1 5, H2 5; counterbore corner radius max 1 mm. Installation allowance at 500 mm spacing (no preload): 30 um parallelism and 130 um height error, proportional to real spacing. LSH25 maximum rail length is 4040 mm. No load rating is quoted for a rail-only item - it belongs to the carriage.
One 880 mm hardened profile rail at H grade, S20 end-hole offset, with bolt caps supplied for the mounting holes - seat each cap flush in its counterbore and tap it home with a plate and plastic mallet, or swarf will work into the ball circuit once a carriage runs. No carriage, preload or lubrication is included. Any LSH25 carriage you order must carry pairing code E to match this rail; the code links a specific block and rail for guaranteed running quality.
