Airtac LSH Linear Guide Rail LSH30BK-F2L-N-D-M6
The AirTAC Airtac LSH Linear Guide Rail LSH30BK-F2L-N-D-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 LSH30BK-F2L-N-D-M6
The F2 in LSH30BK-F2L-N-D-M6 is the headline: a bottom-flange, long-body carriage in size 30 at normal accuracy, M6 lubricated, pairing D, supplied as the block alone - no rail, and no preload position in the code, since preload is set by the mating rail. Mounting through the flange from underneath leaves the carriage's top face completely flush, which is why bottom-flange blocks are chosen wherever a machine table, guard or workpiece must pass over the guide. The series rides a 28 mm wide rail; size code 30 does not equal width. Inside, four rows of balls at 45 degree X-arc raceways, two-point contact per ball, give equal capacity in all four directions and self-align against slight mounting error.
Per-carriage capacity is 45.7 kN dynamic, 73.1 kN static, with 0.88 / 0.91 / 0.91 kN.m of MR / MP / My. The long body earns these over the standard block - roughly 22 percent more dynamic rating and a third more moment. One assembly caution from the catalogue: side-mounted grease nipples and tube fittings are not recommended on flange-type carriages because the fitting can foul the carriage, so verify clearance around the M6 point before fixing neighbouring structure.

Where the Airtac LSH Linear Guide Rail LSH30BK-F2L-N-D-M6 Is Used
Overhead gantry runner
On a shop-floor overhead gantry, trolleys run on guides fixed above head height. A bottom-flange block keeps the runner's underside flat and snag-free, and the long body's moment rating copes with the swing of a suspended load.
Conveyor reject-gate overhaul
Reject gates on a bottling line divert product off the belt thousands of times a day. Replacing the tired guide carriages during a maintenance window - pairing D to match the existing rail - removes the notchy travel that mis-diverts bottles.
Grinder guard-side slide
On a surface grinder, the slide nearest the guarding sees swarf and coolant splash. A sound long carriage with fresh grease, bolted from below so the guard plate sits flush, restores that axis of travel without exposing the ball circuit to grit.
Is the Airtac LSH Linear Guide Rail LSH30BK-F2L-N-D-M6 the Right Guide?
Plan the mounting surface around the flange. Because F2 bolts from below, the substrate needs tapped holes positioned for the flange overhang, and the corner radius at the rail shoulders must not exceed 1 mm on this size. If your duty is light and space is tight, LRM steps down - we confirm its unpublished ratings with you. If the job needs crossed-roller rigidity over a short stroke, step across to LGC. If moment, not load, is the governing figure, either this long body or one size up (LSH35, orderable) is the answer. Checklist: carriage-only form, size by load AND moment, F2 bottom flange, long body, accuracy N, M6 fitting, pairing D to match the rail.
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 LSH30BK-F2L-N-D-M6 FAQ
Dynamic rating C 45.7 kN; static C0 73.1 kN; moments MR 0.88, MP 0.91, My 0.91 kN.m, all per carriage. Running parallelism at grade N spans 12 to 37 um depending on rail length. The rail it mates with uses M8 screws at 3040 N.cm torque in steel, 2010 in cast iron, 1470 in aluminium. Grease: 7.2 cm3 of Mobilux EP2 in the block as supplied, 2.2 cm3 at each top-up, interval 100 km of travel or 3 to 6 months, whichever comes first.
There is no rail - this is the carriage only, sold under pairing code D. Preload does not appear in a carriage-only code because it is established by the carriage-and-rail combination: order an LSH30RLX rail with code D to complete the guide, or a full set if you want preload specified in the order. Match the letter exactly, and confirm the flange-side fitting clearance before final assembly.
