Airtac LSH Linear Guide Rail LSH20HN1X260S10AP-M6
The AirTAC Airtac LSH Linear Guide Rail LSH20HN1X260S10AP-M6 is a standard-type profile linear guide on a 20 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 LSH20HN1X260S10AP-M6
LSH20HN1X260S10AP-M6 specifies a full LSH20 guide: one compact square carriage of standard length riding a 260 mm profile rail of true 20 mm width, with the mounting holes set 10 mm in from the rail ends (the S10 offset) - worth checking against your stroke end stops before drilling the bed. Four rows of balls engage 45 degree X-shaped arc raceways with two contact points each, so loads are equal in all four directions and slight mounting misalignment is absorbed inside the carriage. Accuracy grade is P (precision), preload A (none), grease point M6.
The P grade is the headline: running parallelism of 3-21 um over this rail, the tightest band size 20 offers. Per-carriage ratings are 18.6 kN dynamic C and 28.6 kN static C0, with moments of 0.27 / 0.25 / 0.25 kN.m for MR / MP / My. Two cautions from the maker shape the install: the self-aligning property covers only slight mounting error within its published allowance, and the accuracy you measure depends heavily on seating the rail flat and torquing every M5 screw correctly - P grade on a mediocre surface wastes money.

Where the Airtac LSH Linear Guide Rail LSH20HN1X260S10AP-M6 Is Used
Metrology positioning stage
A dial-indicator or laser-autofocus traverse in a lab jig: P grade holds 3-21 um of running parallelism, tight enough for repeatable probe positioning over the full 260 mm rail.
Gauge fixture for machined housings
A camera sweeping a cast housing bore on a checking fixture; the 10 mm S10 end offset lets the stroke start closer to the fixture edge, and 28.6 kN static capacity absorbs clamping preload.
High-speed dispensing head
A glue nozzle shuttling across PCB panels; grease lubrication supports travel up to 60 m/min where no cooling effect is needed, and P grade keeps the bead line straight stroke after stroke.
Is the Airtac LSH Linear Guide Rail LSH20HN1X260S10AP-M6 the Right Guide?
For a precision slide, match the grade to what the machine actually measures, not to the best number on the page. If N grade parallelism (12-37 um on this size) already satisfies the application, save the difference. Step down to LRM only when the envelope is tight and the duty light - its load ratings are not published, so we confirm those with you first. If a cantilevered optics head drives the moment, a long LSH20 L block or a move to LSH25 buys moment capacity faster than load; for short travel needing crossed-roller rigidity rather than recirculating smoothness, LGC fits better. Check before ordering: complete set form; size 20 by load and moment; square standard carriage, one off; 260 mm rail; P accuracy; preload A; M6 grease point. Adding preload C would stiffen the system but tightens the fit-up: allowable height error falls from 130 to 50 um and parallelism from 25 to 18 um per 500 mm of spacing, so surface quality must rise with it.
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 LSH20HN1X260S10AP-M6 FAQ
The size 20 standard carriage is rated 18.6 kN dynamic (C) and 28.6 kN static (C0), with moment limits MR 0.27, MP 0.25 and My 0.25 kN.m. P grade running parallelism is 3-21 um on this 260 mm rail. Rail fixing: M5 screws at 882 / 588 / 441 N.cm in steel / cast iron / aluminium. Lubricate with Mobilux EP2 - 1.8 cm3 first charge and 0.6 cm3 per top-up, repeated every 100 km of travel or every 3 to 6 months.
Two habits matter most. First, seat the rail hard against its datum and torque every M5 screw correctly - the maker states this has a large effect on the accuracy achieved. Second, respect the mounting allowance: with this SKU's no-preload A grade, size 20 tolerates 130 um height error and 25 um parallelism per 500 mm of spacing; a preloaded version narrows those windows to 85 or 50 um and 20 or 18 um. Also drive the supplied bolt caps fully flush into the rail holes - a proud cap admits swarf to the ball circuit.
