This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X50FA, 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 SU50X50FA
The AirTAC Airtac SU32~50 Standard Cylinder SU50X50FA is a double-acting profile-type standard cylinder with a Ø50mm bore and 50mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X50FA, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X50FA
The AirTAC SU50X50FA is a discontinued double-acting profile-type cylinder with a 50mm bore and 50mm stroke. It delivers 982N push force at 0.5MPa through a 1/4-inch port. AirTAC replaced this unit with the SAU50X50FA, a direct upgrade retaining the exact bore, stroke, output force, port size and SC-series FA mounting accessory.
Because this legacy SKU lacks a magnet, it cannot accept a position switch. The SAU upgrade also modernizes sensing to CMSG/DMSG/EMSG switches if you later need them, and introduces a SAUF valve-integrated variant the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X50FA 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 SAU50X50FA produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -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 SU50X50FA Is Used
Clamping Mechanisms
Ideal for securing mid-weight workpieces during machining, utilizing the 982N push force at 0.5MPa for rigid holding.
Short-Stroke Diverting
Executes 50mm travel to push or sort components on a production line, fitting neatly into compact machinery via the FA mount.
Replacing the Airtac SU32~50 Standard Cylinder SU50X50FA with the SAU50X50FA
To replace the discontinued SU50X50FA, order the SAU50X50FA. Confirm the 1/4-inch port, M16x1.5 rod thread, PT/G/NPT thread standard, and the SC-series FA front mounting bracket. Since this SKU has no -S magnet, it cannot support sensors; if you require position detection on the new unit, specify an SAU-S model and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. If you need to downsize, a 40mm bore yields 628N push at 0.5MPa; if you need more force, a 63mm bore provides 1559N. Note that a plain cylinder drifts without live air—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for secure load holding. The SAUF variant with a built-in 4M solenoid valve is also worth considering for self-switching tasks.
Replacement checklist
- ✓ Same bore / stroke → SAU50X50FA
- ✓ 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 SU50X50FA FAQ
Yes, the AirTAC SU50X50FA is discontinued. The direct replacement is the SAU50X50FA. It shares the identical 50mm bore, 50mm stroke, 982N force, 1/4-inch port and SC-series FA mounting, so it fits the same application without mechanical changes.
At 0.5MPa it provides 982N push and 825N pull force, increasing to 1374N push at 0.7MPa, with a theoretical max of 200kgf at 1.0MPa. This specific SKU lacks a magnet and cannot accept sensors; the SAU replacement supports CMSG/DMSG/EMSG switches if you order the -S version.
