Airtac LSH Linear Guide Rail LSH30BK-F1N-N-D-M6
The AirTAC Airtac LSH Linear Guide Rail LSH30BK-F1N-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-F1N-N-D-M6
This is a single AirTAC LSH30 carriage, size 30, F1 flange with top-face bolt holes, standard length, normal accuracy, pairing code D, M6 fitting. It is sold as the block alone - NO RAIL IS SUPPLIED with this code. Balls run in four rows of 45 degree X-profile raceways, so the block carries the same rating in every direction and soaks up small mounting errors rather than binding on them. Because the flange bolts down from the top, keep the mating face flat and the corner radii at or below the 1 mm maximum for this size; how firmly the mating rail is pulled flat and torqued has a large bearing on the accuracy the pair actually achieves. The rail beneath is 28 mm wide.
Installation latitude is finite even with self-alignment. At 500 mm rail spacing the catalogue allows 40 um of parallelism error for pairs without preload or with light preload, tightening to 27 um at medium preload, and 170 um of height error tightening to 90 um - values that scale with actual spacing. That is the frame this 37.4 kN dynamic / 55.0 kN static block drops into; treat self-alignment as absorption of slight error within these numbers, never as a substitute for machining the surface.

Where the Airtac LSH Linear Guide Rail LSH30BK-F1N-N-D-M6 Is Used
Extruder die-change cart
A heavy die carriage rolled out on size 30 rails for tool changes puts its weight straight down through the flange bolts; fitting a fresh F1 block - pairing code D - restores the low-friction roll without altering the cart's bolt pattern.
Body-in-white fixture rail
Automotive fixture slides that position clamping units bolt the carriage down from the top into a machined fixture plate; this top-flange replacement keeps the fasteners accessible for periodic torque checks on a line that runs shift after shift.
Shaft straightening press table
The support table of a straightening press travels under point loads that stress the block in pure vertical direction; a size 30 top-flange carriage with matching pairing letter carries the 55.0 kN static figure such renewals are sized on.
Is the Airtac LSH Linear Guide Rail LSH30BK-F1N-N-D-M6 the Right Guide?
Start from the mounting surface you have: on an unmachined plate with generous corner radii, a square carriage or a lighter LRM guide may be more forgiving, though LRM's load ratings are not published and we confirm them at RFQ; short-travel jigs needing crossed-roller rigidity point to LGC instead. If the duty is moment-heavy, remember the pattern: a long LSH30 block, or one step up to LSH35 where MR goes from 0.66 to 1.05 kN.m, buys far more moment capacity than extra load rating.
Ordering checklist: this is carriage-only, so pairing code D must match your rail; size 30 verified against both load and moment; F1 top-flange, standard length; accuracy N; no preload segment in this code; M6 nipple from the size 20 to 35 family - and note the catalogue does not recommend side-mounted fittings on flange-type carriages, so confirm the fitting position and clearance against the drawing before machining access.
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-F1N-N-D-M6 FAQ
For this size 30 standard-length block: dynamic C 37.4 kN, static C0 55.0 kN, moments MR/MP/My 0.66/0.67/0.67 kN.m; grade N running parallelism 12-37 um across rail lengths; M8 rail screws at 3040/2010/1470 N.cm for steel, cast iron and aluminium; grease 5.4 cm3 initial charge, 1.7 cm3 top-up, interval 100 km of travel or 3 to 6 months.
One carriage, nothing else: no rail, no bolts, and no preload selection in the code. The D is the pairing letter - rails and carriages must share it to run correctly, so lift it from the old block or the rail end and quote it back through the RFQ if you are unsure. While the block is off, check that the rail's bolt caps sit flush in their counterbores; caps standing proud or missing let swarf into the ball circuit.
