This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X500-10S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAU replacement uses the same profile body, bore, stroke, force and SC-series mounting. It moves to the current CMSG / DMSG / EMSG sensor switches (the SU used CS1-B / DS1-B) and adds the SAUF valve-integrated option.
Airtac SUJ Adjustable Cylinder SUJ40X500-10S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X500-10S is a double-acting profile-type standard cylinder with a Ø40mm bore and 500mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ40X500-10S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X500-10S
The AirTAC SUJ40X500-10S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 490-500 mm stroke from the 500 mm nominal maximum. This compact extruded barrel is shorter than an ISO 15552 cylinder of the same bore and uses adjustable 21 mm cushions at each end.
This SUJ40X500-10S unit is discontinued; the direct replacement is the SAUJ40X500-10S, retaining the same force, port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy model uses CS1-B/DS1-B switches. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ40X500-10S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAUJ40X500-10S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 40 | Bore size in mm. |
| ×500 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
Legacy SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Where the Airtac SUJ Adjustable Cylinder SUJ40X500-10S Is Used
Probe Contact Tuning
Trimming the final 10 mm of extend stroke on-site to set precise contact force against a test probe without machining hard stops.
Sorter Diverter Timing
Adjusting the extend endpoint by a few millimetres to synchronize a diverter gate with varying product sizes on a packaging line.
Pallet Stop Positioning
Fine-tuning the extended stop position by up to 10 mm to accommodate slight pallet width variations in a handling cell.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X500-10S with the SAUJ40X500-10S
To replace the discontinued SUJ40X500-10S, order the direct replacement SAUJ40X500-10S, matching the 40 mm bore, 500 mm stroke, 1/4" port, and FA/LB mounting. Choose the 10 mm adjust window if you need minor on-site extend trimming (490-500 mm); for larger trims, select a larger adjust suffix. Because this unit has a -S magnet, upgrade your legacy CS1-B/DS1-B sensors to CMSG/DMSG/EMSG switches. At 500 mm stroke, prevent rod bending by supporting the load with external guides to minimize side-load. The stop screw sets end position only; it is not a lock, so add a pilot-operated check valve or external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X500-10S
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SUJ Adjustable Cylinder SUJ40X500-10S FAQ
Yes, the SUJ40X500-10S is discontinued. The direct replacement is the SAUJ40X500-10S, which matches the 40 mm bore, 500 mm stroke, 1/4" port, and FA/LB mounting. You must upgrade the legacy CS1-B/DS1-B sensors to the current CMSG/DMSG/EMSG switches.
The external stop screw window is 10 mm, allowing you to shorten the 500 mm maximum extend stroke down to 490 mm on-site. The stop sets end position and is not a load lock.
