  • Ready in 3–5 business days. That is the time we take to process the order and hand it to the carrier. Transit time after that depends on the destination.

About the AirTAC LSH20HN

The AirTAC LSH20HN is an LSH standard linear guide assembly: a size 20 rail (20 mm wide) with square blocks of standard length. Each block is rated C 18.6 kN dynamic and C0 28.6 kN static, with allowable static moments MR 0.27, MP 0.25 and MY 0.25 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 M5 bolts and are made up to 4040 mm in one piece; longer rails are spliced. This page lists 126 stocked assemblies; preload: none, light, medium; accuracy: normal, high, precision.

Where the LSH20HN Is Used

Transfer and handling units

Conveyors, pick-and-place units and small linear slides.

Machine tools

NC lathes, EDM machines, machining centres and tool guides.

Precision stages

XY tables, measuring equipment, semiconductor and robot axes.

Choosing the Right LSH20HN Configuration

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.

AirTAC LSH20HN FAQ

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.

Usually yes. Request a quote with the full order code and we will confirm price and lead time.

No. You can order a single LSH20HN item. Orders are processed and handed to the carrier within 3-5 business days.
