The AirTAC LSH25F1N is an LSH standard linear guide assembly: a size 25 rail (23 mm wide) with flange block, top mountings of standard length. Each block is rated C 26.9 kN dynamic and C0 39.4 kN static, with allowable static moments MR 0.44, MP 0.38 and MY 0.38 kN·m.
The rail uses an X-type (45° / -45°) arc groove with four rows of balls at a 45° contact angle, so the guide self-aligns, takes equal load in four directions and can be preloaded for rigidity. Blocks and rails of the same size are interchangeable. Rails are fixed with M6 bolts and are made up to 4040 mm in one piece; longer rails are spliced. This page lists 8 stocked assemblies; preload: none, light; accuracy: normal, high.

Start with the rail length. The S value is the distance from the rail end to the first mounting hole; if you need another length or end distance, request a quote.
Then choose how many blocks run on each rail: more blocks share the load and raise moment capacity.
Finally pick preload and accuracy. Preload A (none) suits light loads and smooth travel; B (light), C (medium) and D (heavy, sizes 25 to 45) add rigidity for overhung or vibrating loads. Accuracy N (normal), H (high) and P (precision) set running parallelism: about 12-37 µm, 7-28 µm and 3-21 µm depending on rail length.
A = no preload, B = light, C = medium, D = heavy (sizes 25 to 45 only). More preload means a stiffer guide but slightly more running resistance.
Yes. Blocks of the same size can be fitted to any LSH rail of that size and keep their smoothness, preload and accuracy, as long as the matching code is right.
