Airtac LSH Linear Guide Block LSH15BK-HN-P-C-M4
The AirTAC LSH Linear Guide Block LSH15BK-HN-P-C-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-C-M4
When an LSH15 axis starts to feel rough, the rail is usually still sound - it is the block that has worn. This listing answers exactly that case: a precision grade, standard-length square carriage for the 15 mm wide LSH15 rail, pairing code C, M4 nipple fitted, and no rail in the box. The economics are the point: a carriage alone costs roughly a quarter of a complete set, so replacing the block is normally the economical repair. Inside, four rows of balls recirculate through X-arranged 45 degree arc raceways, holding the load equally in four directions and absorbing slight mounting-surface error within the catalogue's limits.
Two numbers deserve a second look before you order. Static rating C0 is 17.9 kN against a dynamic rating C of 11.3 kN - static sits at roughly one and a half times dynamic across this range, but C is the figure that governs travel life, so size on it; keep C0 in reserve for shock and stationary loads. Moment capacity is 0.12 kN.m per axis on this standard-length block, and precision grade running parallelism spans 3 to 21 um.

Where the Airtac LSH Linear Guide Block LSH15BK-HN-P-C-M4 Is Used
SMT feeder shuttle overhaul
Pick-and-place feeders shuttle thousands of cycles a day on short guide rails. When the shuttle starts to notch at stroke ends, a precision block coded C replaces the worn one and the feeder is back in the magazine within minutes.
Cartoning machine pusher slide
The pusher that folds cartons on a packaging machine slides on small profile rails. Blocks wear from dust-laden board; replacing only the carriage keeps the spare parts bill at a fraction of a full set.
Robot end-effector slide rebuild
A servo gripper slide on a handling robot uses a short LSH15 rail. A scored block shows up as angular play at the fingertips; a precision grade replacement with matching C code removes it without touching the robot calibration.
Is the Airtac LSH Linear Guide Block LSH15BK-HN-P-C-M4 the Right Guide?
Before committing, inspect the rail: run a finger along the raceway for scoring or pitting, and check the mounting holes are still torqued flat. A sound rail justifies a carriage-only order; a damaged rail means a complete set, because a new block on a bad rail never recovers its accuracy. If the replacement still fails the duty, work outward from here: LRM suits compact light-duty frames though its ratings are unpublished and need our confirmation; LGC suits short travels wanting crossed-roller stiffness; one size up to LSH20, or a long carriage on the same rail pitch, buys moment headroom beyond 0.12 kN.m. Order checklist: form (carriage only), size verified against load and moment, block style and length, carriage count and rail length, accuracy and preload grades with their installation trade-off, a grease fitting from the size 15 M4 family, and pairing code C read off the original part.
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-C-M4 FAQ
Standard-length size 15, precision grade: dynamic load rating 11.3 kN, static 17.9 kN, allowable static moments 0.12 kN.m on all three axes, running parallelism within the 3-21 um band. The mating rail clamps down with M4 screws at 412 N.cm (steel), 274 N.cm (cast iron) or 206 N.cm (aluminium). Lubrication from new is Mobilux EP2, 0.9 cm3 first fill, 0.3 cm3 top-ups, refreshed every 100 km of travel or 3 to 6 months.
One carriage only - square, standard length, precision grade, with its M4 nipple. No rail, no screws, no bolt caps are included. Fit is guaranteed by the pairing code C: every LSH15 carriage and rail carries a matching letter, and any LSH15 carriage fits any LSH15 rail of the same model. Take the letter from the end of the old part's code; if only the rail code survives, its letter is the one to order against.
