Airtac LSH and LSD rail specifications and prices

Every figure below is generated from the same catalogue the rail calculator prices from, so it cannot drift. Prices are per rail in single quantity, including the $10.00 cut charge, and exclude freight and tax.

Any length is available, not only those shown. The mounting hole pattern follows L = (n−1)·P + S + E, where the last edge distance E is whatever the length leaves once whole pitches are counted, and must fall inside the permitted range for that rail.

Carriage blocks

Flange and square carriage blocks. A block fits only a rail of the same series and size.

Interchange

The LSH series shares every mounting dimension with the Hiwin HG profile — assembly height, block width, bolt pattern, rail section and mounting-hole pitch — at every size from 15 to 45 mm, so it fits designs built around that standard. Rails are cut with a 20 mm standard edge pitch, matching the HG hole pattern, so a replacement lands on the holes already in the machine without re-drilling. Load ratings differ between manufacturers even where dimensions are identical: compare the figures above against your application.

Paste a Hiwin part number into the interchange checker to see the Airtac equivalent.

How pricing works

Prices are Airtac list plus a 150% markup, with the $10.00 cut charge added as entered and never marked up. A rail is priced on the length actually cut, not a grid-snapped length. Volume and repeat orders are quoted lower — request pricing.
