Airtac LSH Linear Guide Rail LSH20HN1X145S10AN-M6
The AirTAC Airtac LSH Linear Guide Rail LSH20HN1X145S10AN-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 LSH20HN1X145S10AN-M6
This listing is the complete set LSH20HN1X145S10AN-M6: a 145 mm LSH20 profile rail with a single square (H) standard-length carriage matched to it, so you receive one working guide rather than separate parts. Four rows of balls run in X-arranged arc raceways at a 45 degree contact angle, giving the size 20 carriage equal capacity up, down and sideways, plus enough self-alignment to absorb slight mounting-surface error instead of binding. Size 20 really is 20 mm of rail width; the trap only starts at size 25.
Per carriage the catalogue rates this configuration at 18.6 kN dynamic (C) and 28.6 kN static (C0), roughly a 1.5 ratio, so size on C for travel life and treat C0 as the margin, not the headline. The S10 end offset puts the first M5 bolt hole just 10 mm from the rail end, which helps when a machine wall or stop sits close to the stroke limit. At 145 mm this rail sits far below the 4040 mm maximum for size 20, so the same carriage can later move onto a longer rail if the machine grows.

Where the Airtac LSH Linear Guide Rail LSH20HN1X145S10AN-M6 Is Used
Pick-and-place head slide
A small XYZ pick-and-place moving SMD trays between feeder and test nest: the 145 mm rail gives a short, accurate shuttle and the square block carries the gripper downforce with equal capacity on the return stroke.
Vision camera traverse
Riding an inspection camera over PCBs on an AOI bench, the block's four-row 45 degree geometry keeps the image plane steady whether the load presses down or a bracket overhangs the side.
Carton pusher on a packaging line
A pusher slide that diverts small cartons between conveyor lanes, cycling thousands of times a shift; the 100 km grease interval and the Mobilux EP2 charge keep maintenance predictable.
Is the Airtac LSH Linear Guide Rail LSH20HN1X145S10AN-M6 the Right Guide?
Decide the duty first. If the payload is light and the envelope tight, step down to AirTAC's LRM miniature series and let us confirm its ratings against your load - LRM figures are not published the way LSH's are. If instead a cantilevered or offset load is what limits you, the moment is the number to watch: one step up to LSH25 N raises MR from 0.27 to 0.44 kN.m, about 63 percent for a single part, while a second carriage on this rail tackles tipping along the travel rather than sideways moment. Where travel is short and the job needs crossed-roller stiffness rather than long recirculating travel, compare the LGC series. Before ordering, tick off: the form (this is a complete rail-plus-carriage set), size chosen by load AND moment, carriage style and length, block count and rail length, accuracy grade and preload remembering tighter preload means a tighter mounting tolerance, the grease fitting (the M6 family suits sizes 20 to 35), and the pairing code only if you are replacing a single part.
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 LSH20HN1X145S10AN-M6 FAQ
Per carriage: dynamic (C) 18.6 kN, static (C0) 28.6 kN, allowable moments MR 0.27 / MP 0.25 / My 0.25 kN.m. N-grade running parallelism is 12 to 37 um over the length band. Rail fixing is M5 screws at 882 N.cm into steel, 588 N.cm into cast iron, 441 N.cm into aluminium. The block leaves the works with 1.8 cm3 of Mobilux EP2; top up 0.6 cm3 every 100 km of travel or every 3 to 6 months, whichever comes first, then stroke the block at least three lengths and check for an even film on the rail.
Preload B or C raises rigidity but shrinks the installation window. On LSH20 the allowable height error between rails falls from 130 um with no preload to 85 um at preload B and 50 um at preload C, per 500 mm of spacing, and the parallelism tolerance drops from 25 to 20 to 18 um. This SKU is preload A (none), the forgiving choice - keep it unless your axis genuinely needs the extra stiffness against vibration or reversal shock.
