Airtac LSH Linear Guide Block LSH30BK-F2L-P-C-M6
The AirTAC LSH Linear Guide Block LSH30BK-F2L-P-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 Block LSH30BK-F2L-P-C-M6
A single precision-grade carriage from the AirTAC LSH30 series, supplied as the block alone: the rail is NOT part of this SKU. This is the F2 flange block, long body, mounting from below through the flange so the machined top face can carry the load plate undisturbed. Four rows of balls run at 45 degrees in X-arranged arc grooves, two points of contact per ball, which is what lets the block even out small errors in the mounting surface rather than jamming on them. The size code says 30 but the rail it runs on is 28 mm wide - worth checking before you cut the mounting pad.
Precision grade P is the headline: running parallelism sits in a 3 to 21 um band, the tightest of the three LSH grades. Ratings per block are 45.7 kN dynamic (C) and 73.1 kN static (C0), with moment limits MR 0.88, MP 0.91 and My 0.91 kN.m. Static runs about 1.6 times dynamic across this range - size the axis on C for travel life and treat C0 only as a shock and contamination check.

Specifications follow the official AirTAC LSH catalogue. The catalogue page does not state the carriage or rail base material. Sizes 35 and 45 exist in the catalogue but are not listed here; they are available to order. This item is a carriage only. Order a complete set if you also need a rail.

This is a carriage on its own. NO RAIL IS INCLUDED. If you are not sure which form you need, send us the machine or the original part number and we will confirm it before you order.
Where the Airtac LSH Linear Guide Block LSH30BK-F2L-P-C-M6 Is Used
Optical inspection camera slide
A precision-grade block on a 28 mm rail suits a camera carriage for lens and PCB inspection, where 3-21 um running straightness is the point.
Surface grinder infeed slide retrofit
Swapping an older grinding slide to this precision-grade long block tightens up the vertical feed without redesigning the machine base.
Adhesive dispensing gantry
Consistent bead placement needs repeatable guidance; the bottom-flange F2 body fixes up under the dispensing head plate with no fasteners on top.
Is the Airtac LSH Linear Guide Block LSH30BK-F2L-P-C-M6 the Right Guide?
Check both directions before you settle: for light duty in a small envelope LRM is the smaller step, though its load ratings are unpublished and need confirming case by case; for short travel where crossed-roller rigidity matters more than long recirculating travel, compare LGC. If neither load nor moment fits, the next lever is a size step to LSH35 (available to order) rather than more blocks. This long F2 body already buys about 22 percent more dynamic rating and about 33 percent more roll moment than the standard LSH30 block.
The order checklist: confirm the form (this is carriage only - no rail in the box), size against both load and moment, carriage style and length, block count and rail length for the axis, accuracy grade - P here, with the machining cost that implies - preload grade on the matching set code, grease fitting, and the pairing code letter, which is C on this block and must 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 Block LSH30BK-F2L-P-C-M6 FAQ
Per block: C 45.7 kN dynamic, C0 73.1 kN static, allowable moments MR 0.88 / MP 0.91 / My 0.91 kN.m. Precision grade P running parallelism: 3 to 21 um across the rail length range. Companion rail screws are M8, torqued to 3040 / 2010 / 1470 N.cm on steel / cast iron / aluminium. Lubrication: 7.2 cm3 first fill of Mobilux EP2 or equivalent, 2.2 cm3 top-ups, repeated every 100 km of travel or 3 to 6 months, whichever comes first.
One carriage only. There is no rail in this delivery and the block cannot run without one. LSH rails and carriages carry a pairing code - a single letter - and only matching letters work together; this block is coded C. If you are building new, either order a complete LSH30 set or add an LSH30RLX rail coded C.
