Airtac LSH Linear Guide Rail LSH15F1N4X475S17.5CN-AM6
The AirTAC Airtac LSH Linear Guide Rail LSH15F1N4X475S17.5CN-AM6 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 LSH15F1N4X475S17.5CN-AM6
This LSH15 code differs from a standard build in two places: the end-hole offset is 17.5 mm rather than the usual 20, and preload grade C applies medium interference to the ball circuit. You receive one 475 mm profile rail with four F1 top-flange carriages as a single assembly. Each carriage runs four ball rows in X-arranged 45 degree arc raceways with two-point contact per ball - the source of both its equal capacity in all four directions and its self-alignment on imperfect seats. The 15 size code equals a true rail width of 15 mm.
Rigidity at grade C is real but paid for at the mounting interface: at 500 mm spacing the allowable height error drops from 130 um with no preload to 35 um here - nearly four times tighter - and parallelism from 25 to 13 um. Load ratings stay at 11.3 kN dynamic, 17.9 kN static and 0.12 kN.m per axis per carriage. Before machining the base, lay the 17.5 mm end offset against your hole pattern: a drawing laid out for the standard S20 spacing will miss the first hole by 2.5 mm. Fixing is M4 screws at 412 N.cm into steel.

Where the Airtac LSH Linear Guide Rail LSH15F1N4X475S17.5CN-AM6 Is Used
Dovetail slide retrofit
Converting a worn dovetail slide on a jig or fixture to rolling contact: medium preload C replaces stiction with stiff, play-free motion, and the F1 flange bolts onto the existing top face.
Optical head trim stage
A fine-position stage carrying a sensor or lens inside an inspection unit: grade C preload removes the play that would otherwise appear as backlash in the positioning loop.
Router table guide upgrade
A small woodworking router table or drilling jig where a worn plain slide binds under cutting forces: four carriages on the 475 mm rail share the thrust, and the 17.5 mm end offset should be checked against the existing holes first.
Is the Airtac LSH Linear Guide Rail LSH15F1N4X475S17.5CN-AM6 the Right Guide?
This is a complete set - rail and four carriages together - so confirm that before ordering it as a spare. Where the duty is light and the envelope slim, AirTAC LRM is the step down, though its load ratings are not published and need confirming with us. If vibration or lost motion is the complaint, medium preload C like this is the right lever; if moment is the constraint instead, go up a size, since LSH25 raises MR to 0.44 kN.m against 0.12 here. For short travels wanting crossed-roller stiffness rather than long recirculating travel, LGC is the alternative. Work the checklist: complete-set form, size against both load and moment, F1 top-flange standard carriage, four blocks, 475 mm rail, accuracy N, preload C and its 35 um height allowance, AM6 fitting, and the pairing letter off any part being replaced.
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 LSH15F1N4X475S17.5CN-AM6 FAQ
Per carriage at size 15 standard length: C 11.3 kN dynamic, C0 17.9 kN static, and MR, MP and My each 0.12 kN.m. N grade rail parallelism runs 12-37 um across the length bands. Rail screws are M4 at 412, 274 and 206 N.cm on steel, cast iron and aluminium. Grease is 0.9 cm3 per carriage at first charge and 0.3 cm3 per top-up, repeated every 100 km of travel or every 3 to 6 months. Because preload C is fitted, also respect the tighter installation allowances: 13 um parallelism and 35 um height error at 500 mm spacing.
Preload C raises rigidity and removes play, but the maker's installation table tightens accordingly: allowed height error falls to 35 um at 500 mm rail spacing versus 130 um for the no-preload version, and parallelism to 13 um, scaled to your real spacing. Self-alignment absorbs only errors inside those figures - it is not unlimited. The delivery is one complete assembly: the 475 mm rail with four F1 carriages fitted, plus screws and bolt caps. Remember the 17.5 mm end offset places the first mounting hole 2.5 mm closer to the rail end than on a standard S20 rail.
