This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X250SH, 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 SU32X250SH
The AirTAC SU32~50 Standard Cylinder SU32X250SH is a double-acting profile-type standard cylinder with a Ø32mm bore and 250mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X250SH, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X250SH
The AirTAC SU32X250SH is a discontinued double-acting profile-type cylinder with a 32mm bore and 250mm stroke. It delivers 402N push and 345N pull at 0.5MPa, utilizing a 1/8" port and M10x1.25 rod thread. AirTAC replaced this end-of-line unit with the SAU32X250SH, a direct alternative retaining the exact bore, stroke, output force, port size, and SC-series mounting compatibility.
This SU variant includes a high-temperature Viton H seal (0-150C) and a piston magnet for legacy CS1-B/DS1-B switches; note the SAU replacement upgrades sensors to CMSG/DMSG/EMSG and offers a SAUF valve-integrated option the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X250SH 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 SAU32X250SH produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

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 SU32X250SH Is Used
Small Part Ejection
Ideal for pushing lightweight machined components out of a fixture with a safe 241N working load at 0.5MPa.
Package Diverting
Handles 250mm diverting strokes on conveyor lines, moving small cartons without overwhelming the 32mm bore.
High-Temp Sorting
The Viton H seal allows reliable 150C operation in heat-shrink tunnels or hot-end packaging sortation gates.
Replacing the Airtac SU32~50 Standard Cylinder SU32X250SH with the SAU32X250SH
To replace this SU32X250SH, order the SAU32X250SH direct equivalent, verifying the 32mm bore, 250mm stroke, 1/8" port, M10x1.25 rod thread, and SC-series mounting. Because this unit has the -S magnet, you must upgrade your sensors: the legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG on the SAU. The -H Viton seal handles 0-150C environments. At 250mm stroke, ensure adequate guidance to prevent rod side-loading and bending. For sizing alternatives, a 40mm bore yields 628N push at 0.5MPa, while a 32mm bore at 0.7MPa yields 563N. A plain cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for held loads. Consider the SAUF if you need a built-in 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU32X250SH
- ✓ 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 SU32X250SH FAQ
Yes, the SU32X250SH is discontinued. The direct replacement is the AirTAC SAU32X250SH. It shares the identical 32mm bore, 250mm stroke, 1/8" port, force, and SC-series mounting, but the SAU uses modern CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B.
The 32mm bore provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N at 0.9MPa, and an 82kgf maximum at 1.0MPa. This -S model has a magnet for legacy CS1-B/DS1-B switches; on the SAU replacement, you must use CMSG/DMSG/EMSG sensors.
