Airtac LSH Linear Guide Rail LSH20RLX580-S20-N-E
The AirTAC Airtac LSH Linear Guide Rail LSH20RLX580-S20-N-E is a standard-type profile linear guide on a 20 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.

About the Airtac LSH Linear Guide Rail LSH20RLX580-S20-N-E
Order this code and you receive one 580 mm length of LSH20 profile rail at normal accuracy grade, drilled for top-lock mounting with the S20 end-hole offset. It is the track only - a carriage is a separate part and must carry the same E pairing code to run on it. The rail is 20 mm wide, matching its size number exactly, and its hardened raceway profile forms X-shaped 45 degree arc grooves for four rows of recirculating balls.
Normal grade running parallelism spans 12-37 um depending on the finished rail length, which suits general automation where the machine frame, not the rail, sets the final tolerance. Shoulder height on a size 20 rail is 4.3 mm with a maximum 0.5 mm corner radius on the abutment, so check the retaining shoulder on your base plate before machining it. At 580 mm the cut still leaves over 3400 mm of headroom below the 4040 mm Lmax for this size.

Where the Airtac LSH Linear Guide Rail LSH20RLX580-S20-N-E Is Used
Belt-width adjuster track
The slide that moves a guide edge across a packaging conveyor as product sizes change: normal grade accuracy is ample, and 580 mm covers most lane adjustments.
Custom glue-dispensing table
A small XY table for adhesive beads built around a 580 mm span, where the machined frame sets final tolerance and the N grade keeps the build budget sane.
Camera tower slide on a PCB line
Raising and lowering an inspection camera over a printed-circuit board conveyor; the rail-only form lets the integrator cut tower height to fit the cell.
Is the Airtac LSH Linear Guide Rail LSH20RLX580-S20-N-E the Right Guide?
Buying rail by the length makes sense when a matched set's fixed lengths do not suit your stroke. Step down to LRM for light duties in a tight envelope (load ratings unpublished - we confirm them with you), step up to LSH25 if a moment calculation comes close to the limit, or across to LGC for short-travel jobs needing crossed-roller stiffness. The checklist: confirm the form is what you need - rail only, no carriage; match the E pairing code; size for both load and moment, not load alone; pick the accuracy grade with installation tolerance in mind; and plan M5 fixings at the correct torque.
Quick checklist
- ✓ Complete set, carriage only, or rail only?
- ✓ Worst-case moment, not just straight load
- ✓ Travel length and mounting space
- ✓ Accuracy grade and preload
- ✓ Mounting surface ground or finish-milled
- ✓ Pairing code, if replacing a part
Installation & Maintenance Notes
- check Mounting surface must be ground or finish-milled.
- check Torque the rail screws per the recommended figures, in sequence.
- check Keep the mounting corner radius inside the stated R maximum.
- check Do not angle the carriage onto the rail; balls can drop out.
- check Drive the supplied bolt caps into the mounting holes.
- check Re-grease every 100 km of travel or every 3–6 months.
- check Installation by qualified personnel per AirTAC docs.
Airtac LSH Linear Guide Rail LSH20RLX580-S20-N-E FAQ
Normal accuracy: 12-37 um running parallelism band. Fixings: M5 screws at 882 / 588 / 441 N.cm (steel / cast iron / aluminium). Shoulder H 4.3 mm, H1 3.5, H2 5, corner radius 0.5 mm maximum. Length 580 mm against a 4040 mm size 20 maximum. Pairing code E. The rail itself has no load rating, no preload and no lubrication charge - all of those belong to the carriages paired with it.
One 580 mm rail and its mounting bolt caps, nothing else: no carriage, no grease fitting, no preload. Bolt caps must be driven flush into the counterbores or swarf reaches the ball circuit later. Pairing: your carriage ordering code must end in the same E letter. If you are replacing an old rail, read the code off the carriage rather than guessing from the size.
