Airtac LSH Linear Guide Block LSH30BK-F2L-P-E-M6
The AirTAC Airtac LSH Linear Guide Block LSH30BK-F2L-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-F2L-P-E-M6
Lubrication is where this SKU starts: a long, bottom-flange F2 carriage from the AirTAC LSH30 series with an M6 grease nipple, shipped pre-filled with Mobilux EP2. It is sold as the carriage alone - NO RAIL IS INCLUDED. One caution from the maker: side-mounted nipples and tube fittings are not recommended on flange-type blocks because the fitting can foul the machine structure, so plan the grease access direction before you design the mount. The block runs on a rail 28 mm wide even though the size code reads 30.
Mechanically it is the four-row, 45 degree X-raceway ball design with two contact points per ball, self-aligning against slight mounting error. Ratings per block: 45.7 kN dynamic (C), 73.1 kN static (C0), moments MR 0.88 / MP 0.91 / My 0.91 kN.m. Precision grade P gives a 3 to 21 um running parallelism band. At high cycle rates the 100 km re-grease distance arrives before the calendar does - a 300 mm stroke cycling once per second covers it in about two weeks of continuous running.

Where the Airtac LSH Linear Guide Block LSH30BK-F2L-P-E-M6 Is Used
High-cycle indexing station
A 300 mm stroke cycling once per second covers the 100 km re-grease distance in about two weeks, so an M6 nipple on a fast indexing axis is not optional.
Bottling line bottle pusher
Bottom-flange mounting under a pusher head on a filling line keeps the carriage top face clear and the grease route away from the product zone.
Planned maintenance route design
This block suits a plant that greases by distance log: 2.2 cm3 top-ups every 100 km of travel or every 3 to 6 months, whichever comes first.
Is the Airtac LSH Linear Guide Block LSH30BK-F2L-P-E-M6 the Right Guide?
Work down the match list: form first - this is carriage only, so you either own a matching LSH30 rail or you order an LSH30RLX rail with the same pairing letter; then size against both load and moment; then style (F2 bolts from below) and length (long, for the moment figure); then block count and rail length; then accuracy grade and, on the matching set code, preload - the tighter the preload, the less mounting error the guide forgives; finally the grease fitting, M6 in this size family. For light duty in a small envelope, step down to LRM and we will confirm its unpublished ratings; for short-travel crossed-roller duty, check LGC; if moment still binds, LSH35 (available to order) is the size step.
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-E-M6 FAQ
Long LSH30 block: dynamic C 45.7 kN, static C0 73.1 kN, allowable moments 0.88 (MR), 0.91 (MP) and 0.91 (My) kN.m; precision grade P parallelism 3 to 21 um; companion rail uses M8 screws torqued to 3040, 2010 or 1470 N.cm on steel, cast iron or aluminium; grease Mobilux EP2, 7.2 cm3 first fill, 2.2 cm3 top-up every 100 km of travel or 3 to 6 months.
One carriage, nothing else: no rail, no screws, no bolt caps. The LSH30 rail it runs on is 28 mm wide and must carry the same pairing code as this block, which is E - read the code off your existing rail before ordering. Rail-only LSH30RLX items and complete sets are listed separately.
