The AirTAC Airtac LSH Linear Guide Block LSH30BK-F2N-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.
This listing is the lubrication half of a linear guide pair: an AirTAC LSH30 F2 bottom-flange carriage, standard length, precision grade, delivered with an M6 grease nipple and pairing code E. It arrives alone - there is no rail in the consignment, and the rail it eventually runs on must be an LSH30, 28 mm wide, marked with the same E code. The block ships pre-filled with Mobilux EP2, and the M6 nipple accepts a standard grease gun for the 1.7 cm3 top-up. Four ball rows sit at 45 degrees in X-pattern arc raceways, giving equal capacity in all four directions and self-alignment against slight seat errors.
Per-carriage figures: 37.4 kN dynamic, 55.0 kN static, moments 0.66 / 0.67 / 0.67 kN.m. One catalogue caution bears directly on this configuration: side-mounted nipples and tube fittings are not recommended on flange-type carriages because the fitting can foul adjacent structure - check the clearance around the M6 nipple in your machine before fixing the block down, and remember a side tube fitting may sit flush with or above the carriage top.

Specifications follow the official AirTAC LSH catalogue. The catalogue page does not state the carriage or rail base material. Sizes 35 and 45 exist in the catalogue but are not stocked here; they are available to order. This item is a carriage only. Order a complete set if you also need a rail.

This is a carriage on its own. NO RAIL IS INCLUDED. If you are not sure which form you need, send us the machine or the original part number and we will confirm it before you order.
A bottling plant's star-wheel transfer slide suits this block: the M6 nipple lets maintenance crews grease the carriage every quarter without dismantling the guarding.
A mechanical press feeder cycling short strokes at high rate burns through its grease distance quickly; the 100 km interval arrives fast, so convenient top-up access earns its keep.
A tube straightener's pressure-die carriage runs slow, greasy and heavily loaded; replacing the block alone keeps the heavy rail in service and the existing grease schedule unchanged.
Choose by duty first: 37.4 kN dynamic and 55.0 kN static per block place this comfortably inside typical conveyor, feeder and handling loads, while a cantilever must be checked against the 0.66 kN.m MR value - a long carriage or the next size up answers moment more cheaply than oversizing the whole axis. If the stroke is short and roller stiffness beats recirculating travel, look at LGC; if the load is light and space tight, LRM, for which load ratings are not published and which we confirm per enquiry. Final checks: carriage-only form, size 30 by load and moment, F2 flange, standard length, one block, P accuracy, M6 nipple with its flange-clearance caveat, and pairing code E matched to the rail it will run on.
Quick checklist
C 37.4 kN, C0 55.0 kN, MR/MP/My 0.66 / 0.67 / 0.67 kN.m, P-grade running parallelism 3-21 um, mating-rail screws M8 at 3040 / 2010 / 1470 N.cm depending on steel, cast iron or aluminium. First grease fill 5.4 cm3, top-up 1.7 cm3, interval every 100 km of travel or 3 to 6 months, whichever comes first.
You receive one F2 bottom-flange carriage with an M6 nipple - no rail, no screws, no bolt caps. Rails and carriages are matched by a pairing letter, and both must read E. Take the letter from the end of your existing rail or the old block; if it is illegible, send us the original code and we will confirm the correct match by enquiry.
