Airtac LSH Linear Guide Rail LSH30BK-F1L-H-C-M6
The AirTAC Airtac LSH Linear Guide Rail LSH30BK-F1L-H-C-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-F1L-H-C-M6
One carriage, no rail: the LSH30BK-F1L-H-C-M6 is a single long top-flange block for the 28 mm LSH30 rail, built to high accuracy grade H and fitted with an M6 lubrication point, pairing letter C. Its four ball rows sit in X-pattern raceways machined at 45 degrees with two contact points per ball, so push, pull, lift and side loads all meet the same capacity, and small errors in the mounting face are absorbed inside the block instead of locking the slide. AirTAC machines every carriage of a model to interchange, so this block runs on any correct rail of the same series.
Grade H holds running parallelism within 7 to 28 um across the catalogue rail-length bands - a real step up from normal grade for a slide that must not wander. Two things outside the part decide how much of that accuracy you actually get: the mating shoulder corner radius must stay at or below 1 mm on size 30, and the rail has to be pulled squarely onto its datum face and torqued correctly before the running quality is judged.

Where the Airtac LSH Linear Guide Rail LSH30BK-F1L-H-C-M6 Is Used
Inspection microscope stage
A coordinate inspection bench whose stage travel has developed stick-slip gets a fresh H-grade block, restoring the 7-28 um parallelism class the optical measurements depend on.
SMT glue dispenser axis
On a surface-mount dispenser the head slide must return to the same pad every cycle; swapping in a high accuracy long flange carriage removes the play a worn standard block developed.
Guided straightening press
A workshop straightening press for shafts rides its ram on profile rails; fitting a new top-flange block on the code C rail restores the self-aligning take-up of slight frame misalignment.
Is the Airtac LSH Linear Guide Rail LSH30BK-F1L-H-C-M6 the Right Guide?
Start by confirming what you actually need: this is a carriage only, so it suits a repair or a build where rails already exist. Match load and moment to the ratings (C 45.7 kN and C0 73.1 kN per block here), then settle style - F1 bolts down through the top flange, which spreads the fixing pattern wider than the body and helps against overturning - and length L for the larger moment figures. Accuracy comes next: H costs more than N but tightens parallelism to 7-28 um, and remember that preloaded complete sets trade installation tolerance for rigidity, so a replacement block should match what the machine was originally built with. Choose the grease point your maintenance routine expects - M6 on this part - and record pairing code C, which the rail must share. Lighter, smaller duties step down to LRM (ratings unpublished; we confirm them per application); short-travel work needing roller stiffness steps across to LGC; heavier moment duties step up to LSH35, available to order.
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-F1L-H-C-M6 FAQ
Design per block on C 45.7 kN dynamic, C0 73.1 kN static, and moment limits of MR 0.88, MP 0.91 and My 0.91 kN.m; the long body earns about a third more moment than the standard LSH30 carriage. Grade H running parallelism spans 7-28 um. Its rail is clamped by M8 screws at 3040, 2010 and 1470 N.cm on steel, cast iron and aluminium respectively. Lubrication is 7.2 cm3 Mobilux EP2 as the first fill and 2.2 cm3 at each top-up, repeated every 100 km or every 3 to 6 months.
No rail is supplied; the part is the block alone. Provided your rail is the same LSH30 model and carries pairing code C, the carriage bolts on without fitting or shimming work, because carriages of a model are built to interchange and keep their smoothness and accuracy on any rail of that model. If the letter on your rail is different, that rail belongs to another carriage - match the letter so the pair keeps the accuracy grade it was matched for.
