Airtac LSH Linear Guide Block LSH30BK-HL-P-C-M6
The AirTAC Airtac LSH Linear Guide Block LSH30BK-HL-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-HL-P-C-M6
The LSH30BK-HL-P-C-M6 is one replacement block: a long square carriage at precision accuracy, greased through an M6 nipple and paired to rails carrying the C code. Nothing else arrives - the rail is a separate purchase. Its four rows of balls seat in 45 degree X-arc grooves with two contact points per ball, giving equal capacity radially, laterally and in overturn, and letting the carriage self-align to small datum errors. Remember that LSH30 rides on a 28 mm rail, not a 30 mm one.
The precision grade holds running parallelism within a 3 to 21 um band across the rail length range. Ratings per block: C 45.7 kN, C0 73.1 kN, MR 0.88 kN.m. The static figure sits near 1.6 times the dynamic value on this size - size on C for travel life, and check C0 only against shock and static overload.

Where the Airtac LSH Linear Guide Block LSH30BK-HL-P-C-M6 Is Used
Die bonder stage overhaul
Rebuilding the part-feed stage of a semiconductor die bonder, where a precision-grade long carriage restores stage travel quality after years of duty cycles.
CT couch carriage swap
A hospital imaging service replacing the slide carriage on a CT patient couch, where smooth quiet travel matters and the couch frame already carries LSH30 rails.
Lab automation upgrade
An analytical instrument maker upgrading a liquid-handling deck axis with precision carriages to hold running parallelism inside the 3 to 21 um P-grade band.
Is the Airtac LSH Linear Guide Block LSH30BK-HL-P-C-M6 the Right Guide?
Start from the numbers, not the size code. Dynamic C 45.7 kN and MR 0.88 kN.m are per-carriage figures; two blocks on one rail roughly double capacity and resist tipping along the direction of travel. Lighter duty with a smaller envelope points down to LRM, whose ratings we confirm on request since none are published. Short-stroke axes needing crossed-roller stiffness fit LGC better. If C is borderline, step up to LSH35, which we also list to order.
Checklist for a like-for-like swap: form (this is a carriage only), size by load and moment, square long carriage, P accuracy, M6 fitting, and the C pairing code matching the rail. Tighter grades reward flat, well-torqued mounting - whether the rail sits pulled hard against its datum face decides how much of that 3 to 21 um band you actually see.
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-C-M6 FAQ
Each long block is rated C 45.7 kN dynamic and 73.1 kN static, with MR/MP/My of 0.88/0.91/0.91 kN.m. The P accuracy grade gives 3 to 21 um running parallelism depending on rail length. Mount the rail with M8 bolts at 3040/2010/1470 N.cm on steel/cast iron/aluminium. Lubrication is Mobilux EP2 or equivalent: 7.2 cm3 to charge, 2.2 cm3 to top up, on the 100 km or 3-to-6-month cycle.
Only if the rail carries the matching C pairing code - that letter is how separately ordered blocks and rails are matched, so quote the code from your original part when ordering. Within the LSH range, a carriage of a given model runs on a rail of the same model; nothing here implies use on another manufacturer's rail. No rail is supplied with this SKU - order a C-coded LSH30 rail separately or choose a complete-set code.
