This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X250SN, 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 SU32X250SN
The AirTAC SU32~50 Standard Cylinder SU32X250SN 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 SAU32X250SN, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X250SN
The AirTAC SU32X250SN is a discontinued double-acting profile-type cylinder with a 32 mm bore and 250 mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 unit of the same bore and delivers a thrust of 402 N at 0.5 MPa. The direct replacement is the SAU32X250SN, which matches the original force, 1/8" port, and SC-series mounting footprint.
This unit includes a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement upgrades this to current CMSG/DMSG/EMSG sensors. The SAU family also introduces the SAUF valve-integrated variant, an option the SU line never offered. The NBR seal supports standard -20 to +70 C operations.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X250SN 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 SAU32X250SN produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SU32~50 Standard Cylinder SU32X250SN Is Used
Small Part Ejection
Ideal for pushing lightweight machined components out of a fixture, utilizing the 402 N thrust safely within the 241 N working load limit.
Package Diverting
Handles 250 mm diverting strokes on a conveyor line, where the compact profile saves space and the 20 kg vertical lift capacity manages small totes.
Bin Gating
Actuates small hopper gates or sorting flaps, benefiting from the adjustable 21 mm cushions to decelerate the 12 mm rod smoothly at cycle end.
Replacing the Airtac SU32~50 Standard Cylinder SU32X250SN with the SAU32X250SN
To replace this discontinued SU32X250SN, order the SAU32X250SN. Verify your 1/8" port (PT/G/NPT), M10x1.25 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). Because this SKU has the -S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. At this 250 mm stroke, guide the load to prevent rod bending and side-load wear. A plain cylinder drifts without live air, so add an external rod lock or pilot-operated check valve for load holding. The SAUF variant offers a built-in valve if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU32X250SN
- ✓ 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 SU32X250SN FAQ
Yes, the AirTAC SU32X250SN is discontinued. The direct replacement is the SAU32X250SN. It provides the same 32 mm bore, 250 mm stroke, 1/8" port, output force, and SC-series mounting compatibility, fitting directly into your existing application.
The 32 mm bore provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical max of 82 kgf at 1.0 MPa. Because this model includes a magnet (-S), it used legacy CS1-B/DS1-B switches; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
