Airtac LSH Linear Guide Rail LSH30HL1X500S10BH-M6
The AirTAC Airtac LSH Linear Guide Rail LSH30HL1X500S10BH-M6 is a standard-type profile linear guide on a 28 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 LSH30HL1X500S10BH-M6
LSH30HL1X500S10BH-M6 is an AirTAC LSH complete set: one long square carriage on a 500 mm rail, lightly preloaded, ground to high accuracy, lubricated through an M6 fitting. The rail is 28 mm wide - the size code exaggerates it - and the four-row, 45 degree ball geometry carries equal load in every direction while absorbing slight mounting error inside the carriage. The pairing of light preload with H grade is the usual choice for an axis that must run without play, but whose mounting surfaces are machined rather than ground.
Rigidity is not free. Preload B cuts the allowable mounting height error at 500 mm spacing from 170 um with no preload to 110 um here, and medium preload would tighten it further to 90 um; parallelism error falls from 40 to 30 um. In return, the carriage runs without visible play against a 0.88 kN.m MR rating, backed by 45.7 kN dynamic and 73.1 kN static per block. High grade holds running parallelism to a 7-28 um band, and 500 mm leaves 3530 mm of the 4030 mm maximum rail length unused if the axis is ever lengthened.

Model Code: Airtac LSH Linear Guide Rail LSH30HL1X500S10BH-M6
| LSH | LSH Series Linear Guide. |
|---|---|
| 30 | Size code — note the rail is 28 mm wide, not 30 mm. |
| H / F1 / F2 / F3 | Carriage style: square, or flange mounted from the top, bottom, or both. |
| L | Long carriage. |
| 1X500 | 1 carriage on a 500 mm rail. |

Where the Airtac LSH Linear Guide Rail LSH30HL1X500S10BH-M6 Is Used
Tool presetter slide
A presetting gauge carriage moving over 500 mm must not rock under its dial-indicator arm; light preload removes play while the long body carries the overturning moment.
Laser alignment axis
Aligning a laser to a workpiece on a 500 mm slide demands repeatable straightness; the 7-28 um high-grade band plus light preload keeps the beam path consistent shot after shot.
Assembly cell feed axis
A screwdriver spindle feeding fasteners in a compact assembly cell rides this preloaded set, where zero play keeps the driver bit seated on the screw head every cycle.
Is the Airtac LSH Linear Guide Rail LSH30HL1X500S10BH-M6 the Right Guide?
Pay for preload only when your machining can support it: if the mating surface is milled to a general tolerance, the tightening from preload B - 170 down to 110 um of allowable height error on this size - may cost more in surface preparation than the added rigidity returns. High accuracy suits most machine-built axes; move up to precision grade only when the application actually measures along the travel. Down-size to AirTAC LRM for light duties in a small envelope - ratings are not published there, so we verify them with you before ordering - and step across to LGC for short travel where crossed-roller rigidity beats long recirculating travel. Before ordering, confirm every line: form, size by load and moment, carriage style and length, block count and rail length, accuracy and preload versus your installation tolerance, grease fitting family, and the pairing code if this joins existing parts.
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 LSH30HL1X500S10BH-M6 FAQ
Per long-body carriage: C 45.7 kN dynamic, C0 73.1 kN static, and moment ratings MR 0.88, MP 0.91 and My 0.91 kN.m. High accuracy holds running parallelism to a 7-28 um band. Mount the 28 mm rail with M8 screws at 3040 / 2010 / 1470 N.cm in steel / cast iron / aluminium. Grease is Mobilux EP2 or equivalent: 7.2 cm3 first fill and 2.2 cm3 top-up per carriage, renewed every 100 km of travel or every 3 to 6 months, whichever comes first.
Preloaded balls press against the raceways, so any twist in the mounting surface is felt directly as extra friction or binding. On this size, at 500 mm rail spacing, no preload tolerates 40 um of parallelism error and 170 um of height error; light preload cuts that to 30 um and 110 um. If your plates are milled rather than ground, either improve the surface or drop to preload A. And remember the rail must be pulled flat against its datum face and fully torqued, or the high-grade figures will not be achieved in practice.
