This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X830S, 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 SU32X830S
The AirTAC SU32~50 Standard Cylinder SU32X830S is a double-acting profile-type standard cylinder with a Ø32mm bore and 830mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X830S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X830S
The AirTAC SU32X830S is a discontinued double-acting profile-type cylinder with a 32 mm bore and 830 mm stroke. It delivers 402 N push and 345 N pull at 0.5 MPa, utilizing a 1/8 inch port. AirTAC replaced this legacy unit with the SAU32X830S, a direct alternative preserving the exact bore, stroke, output force, port size, and SC-series mounting compatibility.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace the older CS1-B/DS1-B switches used on this -S model, and it offers a SAUF variant with a built-in 4M solenoid valve that the SU line lacked. Because the 830 mm stroke is long, external guides are recommended to prevent rod bending under side loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X830S 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 SAU32X830S 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. |
| ×830 | 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.

Compact Assembly Press
Applies 402 N of push force at 0.5 MPa in a tight footprint, using the profile body to save space compared to standard ISO cylinders.
Replacing the Airtac SU32~50 Standard Cylinder SU32X830S with the SAU32X830S
To replace the SU32X830S, order the SAU32X830S direct equivalent, verifying the 32 mm bore, 830 mm stroke, 1/8 inch port, and M10x1.25 rod thread. If downsizing is possible, a 40 mm bore provides 628 N push at 0.5 MPa; if upgrading, a 50 mm bore yields 982 N. Note that the -S magnet requires a sensor family change: the legacy CS1-B/DS1-B switches must be replaced by CMSG/DMSG/EMSG units on the SAU. For the 830 mm stroke, use external guides to prevent rod bending. This cylinder does not hold load without live air; the 21 mm adjustable cushions only decelerate near stroke end, so add a pilot-operated check valve or external rod lock for suspended loads. The SAUF valve-integrated option is available if self-switching is needed.
Replacement checklist
- ✓ Same bore / stroke → SAU32X830S
- ✓ 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 SU32X830S FAQ
Yes, the SU32X830S is discontinued. The direct replacement is the AirTAC SAU32X830S. It matches the 32 mm bore, 830 mm stroke, 1/8 inch port, force, and SC-series mounting, so it fits the same application without mechanical modifications.
The cylinder provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N at 0.9 MPa, and a maximum theoretical force of 82 kgf at 1.0 MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches are obsolete; the SAU replacement uses current CMSG/DMSG/EMSG sensors.
