Airtac LSH Linear Guide Block LSH15BK-HN-P-D-M4
The AirTAC LSH Linear Guide Block LSH15BK-HN-P-D-M4 is a standard-type profile linear guide on a 15 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 LSH15BK-HN-P-D-M4
Lubrication is where most LSH15 blocks actually fail, so this precision grade carriage is written with upkeep in mind. It is the block alone - one square, standard-length carriage for the 15 mm wide LSH15 rail, pairing code D, with an M4 nipple on the body and Mobilux EP2 already inside from the factory; no rail comes with it. The running principle is the standard one for this series: four rows of balls circle through X-arranged raceways set at 45 degrees, so the block reacts vertical, side and lift-off loads equally and tolerates slight mounting-surface error without binding.
Plan the grease schedule around distance, not the calendar. First charge is 0.9 cm3 and each top-up 0.3 cm3, due every 100 km of travel or every 3 to 6 months - and 100 km arrives fast: a 300 mm stroke cycling once a second covers it in about two weeks of continuous running, so the distance binds before the clock does. Mechanically the block is rated 11.3 kN dynamic, 17.9 kN static and 0.12 kN.m of moment per axis, with precision grade running parallelism in the 3-21 um band.

Where the Airtac LSH Linear Guide Block LSH15BK-HN-P-D-M4 Is Used
Semiconductor test handler axis
Test handlers cycle sockets millions of times, so their guide blocks live or die by the grease schedule. A pre-filled precision block coded D, re-greased on the 100 km counter, keeps contact resistance readings stable.
Parcel hub sorter divert arm
The divert arm that pushes parcels off a sorter belt slides on short guide rails all shift. Grease top-ups through the M4 nipple between campaigns stop the block from drying out and flatspotting.
Cable-dressing slide in a laser marking cell
The cable carrier support on a galvo laser marker travels with the head. A precision carriage keeps the dress height constant, and its factory EP2 charge means the first service is a 0.3 cm3 top-up, not a rebuild.
Is the Airtac LSH Linear Guide Block LSH15BK-HN-P-D-M4 the Right Guide?
If your duty cycle is high, decide the lubrication route first. Grease suits speeds to 60 m/min where no cooling effect is needed; oil from 30 to 150 cSt handles all loads and speeds but is consumed faster and dislikes high temperature, with a first charge of 0.6 cm3 fed at 0.2 cm3/h for size 15. Then run the rest of the checklist: form (this code is carriage only - the rail is separate), size chosen on load AND moment together, block style and length, carriage count and rail length, accuracy grade matched carriage-to-rail, preload grade with the reminder that tighter preload shrinks the allowable mounting error, grease fitting limited at this size to the M4 family (M4, AM6, LM6), and pairing code D off the original part. Where the frame is very compact and the duty light, compare LRM (ratings unpublished - we confirm them); where travel is short and crossed-roller stiffness beats long recirculating travel, compare LGC.
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 LSH15BK-HN-P-D-M4 FAQ
Per carriage: basic dynamic load rating 11.3 kN; basic static load rating 17.9 kN; allowable static moments MR 0.12, MP 0.12, My 0.12 kN.m. Precision grade running parallelism spans 3 to 21 um over the rail length. Rail fixing is M4 screws at 412 N.cm into steel, 274 N.cm into cast iron, 206 N.cm into aluminium. Lubrication: Mobilux EP2 pre-filled, 0.9 cm3 first charge, 0.3 cm3 top-up, interval 100 km of travel or 3 to 6 months, whichever comes first.
It contains one carriage only - square type, standard length, precision accuracy, M4 nipple, grease already inside. There is no rail in the box and the price covers the block alone. D is the pairing code: your rail must carry the same letter in its own part number for the two to be matched. Replacing a worn block? Take D off the original carriage's code; if you only have the rail to hand, read the letter off the rail's code instead.
