About the AirTAC LSH20RL
These are LSH standard linear guide rails, size 20 (20 mm wide), sold without blocks. Rails are fixed with M5 bolts; one-piece rails go up to 4040 mm, and the 4000 mm full-length rail can be cut to size.
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. The matching code (D or E) decides which block codes give which preload on this rail.

Where the LSH20RL 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 LSH20RL Configuration
Start with the length: a 4000 mm full-length rail to cut yourself, or a cut rail where S is the distance from the rail end to the first mounting hole.
Then pick the accuracy, N (normal) or H (high).
Finally check the matching code. Blocks are paired to D or E rails; the block page lists which block code gives each preload.
AirTAC LSH20RL FAQ
Yes. The full-length rail is meant to be cut to the length you need; pair it with blocks of the matching code.
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 LSH20RL item. Orders are processed and handed to the carrier within 3-5 business days.
