This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X950S, 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 SU32X950S
The AirTAC SU32~50 Standard Cylinder SU32X950S is a double-acting profile-type standard cylinder with a Ø32mm bore and 950mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X950S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X950S
The AirTAC SU32X950S is a discontinued double-acting profile-type cylinder with a 32mm bore and 950mm stroke. Delivering 402 N push force at 0.5 MPa, it features a compact extruded aluminum body shorter than same-bore ISO 15552 units. AirTAC replaced this EOL unit with the SAU32X950S, a direct matching the 1/8" port, M10x1.25 rod thread, and SC-series mounting.
The SAU upgrade switches the -S magnet to modern CMSG/DMSG/EMSG sensors (retiring the old CS1-B/DS1-B) and adds a SAUF valve-integrated option. Note that a 950mm stroke demands external guides to prevent rod bending, and plain cylinders drift without live air.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X950S 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 SAU32X950S 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 SU32X950S Is Used
Light-Part Ejection
Uses the 402 N push at 0.5 MPa to knock small molded parts off a conveyor line over the 950mm travel distance.
Bin Push-Off
Pushes lightweight packaging bins between sorting stations, benefiting from the compact 32mm profile body.
Replacing the Airtac SU32~50 Standard Cylinder SU32X950S with the SAU32X950S
To replace this SU32X950S, order the SAU32X950S direct equivalent, verifying your 1/8" port, M10x1.25 rod thread, PT/G/NPT thread standard, and SC-series mounting (LB/FA/FB/CA/CB). Because the -S magnet is present, prepare to swap legacy CS1-B/DS1-B switches for the SAU's CMSG/DMSG/EMSG sensors. For load sizing, this 32mm bore yields 402 N push and 345 N pull at 0.5 MPa; if undersized, the neighboring 40mm bore provides 628 N push. A 950mm stroke requires external guide rails to prevent rod bending under side loads. The air cushion only decelerates the piston; for load holding on air loss, install an external rod lock or pilot-operated check valve. If self-switching is needed, the SAU line offers the SAUF built-in 4M valve variant.
Replacement checklist
- ✓ Same bore / stroke → SAU32X950S
- ✓ 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 SU32X950S FAQ
Yes, the AirTAC SU32X950S is discontinued. The direct replacement is the SAU32X950S, which matches the 32mm bore, 950mm stroke, 1/8" port, output force, and SC-series mounting. You just order the SAU equivalent.
The 32mm bore provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and an 82 kgf max at 1.0 MPa. Because your SU has an -S magnet, the SAU replacement requires upgrading from legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensor family.
