This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X240S, 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 SU32~50 Standard Cylinder SU50X240S
The AirTAC SU32~50 Standard Cylinder SU50X240S is a double-acting profile-type standard cylinder with a Ø50mm bore and 240mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X240S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X240S
The AirTAC SU50X240S is a discontinued double-acting profile cylinder with a 50mm bore and 240mm stroke. Delivering 982 N push force at 0.5 MPa via a 1/4" port, it is directly replaced by the SAU50X240S. The SAU direct matches the exact bore, stroke, force, port size, and SC-series mounting, ensuring a seamless upgrade.
This legacy extruded-aluminium profile body is more compact than a same-bore ISO 15552 unit. Because this SKU includes a piston magnet (-S), it originally used CS1-B/DS1-B switches; the SAU successor transitions to modern CMSG/DMSG/EMSG sensors. Furthermore, the SAU line introduces the SAUF variant with a built-in 4M solenoid valve, a self-switching feature the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X240S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAU50X240S 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). |
|---|---|
| 50 | Bore size in mm. |
| ×240 | 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 SU32~50 Standard Cylinder SU50X240S Is Used
Package Diversion
Actuates routing gates on packaging lines, utilizing the 982 N push force at 0.5 MPa to deflect cartons smoothly without bounce.
Clamp Actuation
Drives mid-force clamping mechanisms on CNC machining fixtures, taking advantage of the compact profile body to fit tight cell envelopes.
Replacing the Airtac SU32~50 Standard Cylinder SU50X240S with the SAU50X240S
To replace the SU50X240S, order the SAU50X240S. Verify your 1/4" port threads (PT, G, or NPT) and M16x1.5 rod-end connections. Because the -S magnet is present, prepare to swap legacy CS1-B/DS1-B switches for CMSG/DMSG/EMSG sensors on the new cylinder's groove. For sizing both ways: a 40mm bore provides 628 N push at 0.5 MPa, while a 63mm bore offers 1559 N. The 240mm stroke is well within the 1200mm standard maximum, so no non-standard surcharge applies. Note that a plain cylinder drifts on air loss—the 21mm adjustable cushions only decelerate the piston near stroke end, so add an external rod lock or pilot-operated check valve for suspended loads.
Replacement checklist
- ✓ Same bore / stroke → SAU50X240S
- ✓ 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 SU32~50 Standard Cylinder SU50X240S FAQ
Yes, the AirTAC SU50X240S is discontinued. The direct replacement is the SAU50X240S. It shares the identical 50mm bore, 240mm stroke, 1/4" port, output force, and SC-series mounting, so it drops straight into the same application.
At 0.5 MPa it pushes 982 N and pulls 825 N; at 0.7 MPa it pushes 1374 N, with a theoretical max of 200 kgf at 1.0 MPa. Because this is an -S magnet model, the original CS1-B/DS1-B switches are obsolete; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
