Airtac LSH Linear Guide Block LSH30BK-HL-P-E-M6
The AirTAC LSH Linear Guide Block LSH30BK-HL-P-E-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-HL-P-E-M6
The LSH30BK-HL-P-E-M6 listing is a carriage on its own: a long, square AirTAC LSH30 block at precision accuracy, greased via an M6 nipple and matched by the E pairing code to a same-code rail. No rail ships with it. Inside, four ball rows circulate through X-shaped 45 degree raceways with two-point contact per ball, which balances capacity in every direction and lets the block ride out small mounting inaccuracies. True rail width for this size is 28 mm.
Each block arrives pre-filled with Mobilux EP2; the first charge is 7.2 cm3 and each top-up 2.2 cm3, on a 100 km or 3-to-6-month cycle. The distance binds sooner than it sounds: a 300 mm stroke cycling once per second covers 100 km in roughly two weeks of continuous running. Per-carriage ratings: C 45.7 kN, C0 73.1 kN, MR/MP/My 0.88/0.91/0.91 kN.m.

Where the Airtac LSH Linear Guide Block LSH30BK-HL-P-E-M6 Is Used
Filling line slide spare
A bottling plant holding this E-coded long carriage as the matching spare for the filler-head slide rails already installed along the line.
ASRS shuttle maintenance
A distribution centre's maintenance planner pairing this carriage with an E-code replacement rail for a storage-and-retrieval shuttle due its grease service.
Reject pusher slide
A food packer replacing the carriage on a belt-mounted reject pusher slide, keeping the same rail and avoiding a full-guide changeover on the packing line.
Is the Airtac LSH Linear Guide Block LSH30BK-HL-P-E-M6 the Right Guide?
A carriage-only buy makes sense as a planned spare when the rails in service are sound: keep one per axis, matched by pairing code, and the swap takes minutes instead of a rebuild. Light duty or tight space points down to LRM (ratings not published - we confirm by RFQ); short travel with a need for crossed-roller stiffness points across to LGC; a borderline dynamic load points up to LSH35, which is listed to order.
The pre-order checklist: form (carriage only), size by load and moment, square long block, precision accuracy, M6 grease fitting, and the E pairing code shared with your rail. Verify the mounting print against the real 28 mm rail width rather than the size name, and keep the shoulder figures in mind - H 6.5, H1 5, H2 5 mm with a corner radius of 1 mm maximum.
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-HL-P-E-M6 FAQ
Know the ratings: 45.7 kN dynamic C, 73.1 kN static C0, MR/MP/My of 0.88/0.91/0.91 kN.m per carriage, and a 3 to 21 um parallelism band at P grade. Rail fixing is M8, torqued 3040/2010/1470 N.cm for steel, cast iron and aluminium beds. For grease, inject 7.2 cm3 at first charge or 2.2 cm3 at top-up, then stroke the block at least three carriage-lengths twice and confirm an even film on the rail; repeat every 100 km or every 3 to 6 months.
The E in LSH30BK-HL-P-E-M6 is the pairing code. Rails ordered on their own carry the same letter system, and a block and rail must share it to be matched, so find the E (or other letter) in your existing rail's part number first. This SKU contains no rail at all - one carriage per order. If the original code is lost, send us the old part's details by RFQ and we will identify the correct match.
