Airtac LSH Linear Guide Rail LSH15HN1X195S37.5AN-M4
The AirTAC Airtac LSH Linear Guide Rail LSH15HN1X195S37.5AN-M4 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 LSH15HN1X195S37.5AN-M4
A complete LSH linear guide for short-stroke duty: 195 mm of profile rail, 15 mm true width, carrying one square carriage of standard length, all under a single code. The carriage rides on four recirculating ball rows set at 45 degrees in alternating directions, a geometry that balances capacity vertically and laterally and lets the block self-align to small imperfections in the machine deck. At S37.5 the outermost screw holes sit 37.5 mm in from each rail end, clearing clamps, brackets or rotating parts that overhang the stroke.
Ratings per carriage: 11.3 kN dynamic, 17.9 kN static, moments 0.12/0.12/0.12 kN.m (MR/MP/My). Lubrication timing matters more than most buyers expect on a rail this short: a 100 mm stroke cycling once per second covers the 100 km re-grease distance in about twelve days, so the calendar interval of 3 to 6 months never gets a chance to bind first. If the machine grows, the same model runs to a 4040 mm maximum rail length.

Model Code: Airtac LSH Linear Guide Rail LSH15HN1X195S37.5AN-M4
| LSH | LSH Series Linear Guide. |
|---|---|
| 15 | Size code. |
| H / F1 / F2 / F3 | Carriage style: square, or flange mounted from the top, bottom, or both. |
| N | Standard carriage. |
| 1X195 | 1 carriage on a 195 mm rail. |
| S… | End-hole offset from the rail end, in mm. |

Where the Airtac LSH Linear Guide Rail LSH15HN1X195S37.5AN-M4 Is Used
Vision inspection camera rail
Sliding a camera across PCB panels on an AOI bench; grade N parallelism, inside the 12-37 um band for this rail length, keeps the focal plane steady frame to frame.
High-cycle glue-dot head
A dispensing head repeating a short stroke many times a minute runs out its 100 km grease interval in days rather than months - schedule the 0.3 cm3 top-up by distance travelled.
Comparator gauge translation
Shifting a part between measuring positions on a comparator bench; the 37.5 mm end offset keeps the bench hold-down bolts clear of the outermost rail holes.
Is the Airtac LSH Linear Guide Rail LSH15HN1X195S37.5AN-M4 the Right Guide?
Lead with stroke and layout when choosing here. For a lighter, tighter package, LRM is the step down - its load ratings are not published, so we verify them against your duty before you commit. If the load overhangs, look up-size before up-count: LSH20 lifts MR to 0.27 kN.m, over twice this size. Where the travel is short and the job wants crossed-roller stiffness rather than long recirculating travel, LGC is the cross-grade alternative. A second carriage on this same rail resists tipping along the direction of motion. Buying checklist: confirm the form - this is a complete set; size by both load and moment; block style, length and count; rail length and the S37.5 hole offset; accuracy N with preload A (25 um parallelism and 130 um height error allowed per 500 mm of span); M4 lubrication fitting; pairing code when ordering a spare block alone.
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 LSH15HN1X195S37.5AN-M4 FAQ
Dynamic C 11.3 kN; static C0 17.9 kN; MR/MP/My 0.12/0.12/0.12 kN.m, all per carriage. Running parallelism for grade N spans 12-37 um according to rail length. Mount on M4 screws tightened to 412 N.cm (steel), 274 N.cm (cast iron) or 206 N.cm (aluminium). Grease with Mobilux EP2: 0.9 cm3 first fill and 0.3 cm3 top-ups, due every 100 km of travel or every 3 to 6 months, whichever arrives first.
The delivery comprises a matched set - the 195 mm rail, drilled with holes 37.5 mm from each end, and one square standard carriage with an M4 nipple, pre-filled with Mobilux EP2. No other carriages or rails are included. For the accuracy the grade promises, pull the rail fully against its datum face before final torquing; a rail left slightly gapped loses most of its running parallelism. After greasing, stroke the block at least three carriage-lengths and back, twice, and confirm an even film along the rail.
