This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X100SFA, 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 SU32X100SFA
The AirTAC Airtac SU32~50 Standard Cylinder SU32X100SFA is a double-acting profile-type standard cylinder with a Ø32mm bore and 100mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X100SFA, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X100SFA
The AirTAC SU32X100SFA is a discontinued double-acting profile-type cylinder with a 32mm bore and 100mm stroke. AirTAC replaced it with the SAU32X100SFA, a direct sharing the same body, force, port, and SC-series FA mounting.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used on this -S magnet model. The SAU line also adds a SAUF variant with a built-in 4M valve, an option the SU never had. The extruded aluminum profile remains shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X100SFA carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X100SFA 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). |
|---|---|
| 32 | Bore size in mm. |
| ×100 | 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 SU32X100SFA Is Used
Package Diverting
Actuates a short 100mm stroke diverter arm on a packaging line, pushing lightweight boxes to adjacent lanes at up to 800 mm/s.
Gate Positioning
Controls small access gates or stops in material handling systems, where the compact 32mm profile saves space and the FA mount secures the body.
Replacing the Airtac SU32~50 Standard Cylinder SU32X100SFA with the SAU32X100SFA
To replace this SU32X100SFA, order the SAU32X100SFA, confirming the 32mm bore, 100mm stroke, 1/8" port, M10x1.25 rod thread, and FA mounting. The -S magnet means you must migrate from CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. If downsizing, a 40mm bore gives 628N; if upsizing, note the 32mm max standard stroke is 1000mm. A plain cylinder drifts on air loss—add an external rod lock or pilot check valve to hold loads. For 100mm strokes, side-load is minimal, but always guide the rod to prevent bending.
Replacement checklist
- ✓ Same bore / stroke → SAU32X100SFA
- ✓ 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 SU32X100SFA FAQ
Yes, the AirTAC SU32X100SFA is discontinued. The direct replacement is the SAU32X100SFA. It matches the 32mm bore, 100mm stroke, 402N force, 1/8" port, and SC-series FA mounting, so it fits the same application. You just order the SAU equivalent.
At 0.5 MPa it pushes 402N and pulls 345N; at 0.7 MPa it pushes 563N, with a theoretical max of 82 kgf at 1.0 MPa. Because this is a -S model with a magnet, the original CS1-B/DS1-B switches must be replaced by CMSG/DMSG/EMSG sensors on the new SAU model.
