This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X105S, 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 SU32X105S
The AirTAC SU32~50 Standard Cylinder SU32X105S is a double-acting profile-type standard cylinder with a Ø32mm bore and 105mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X105S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X105S
The AirTAC SU32X105S is a discontinued double-acting profile-type cylinder with a 32mm bore and 105mm stroke. Delivering 402N push force at 0.5MPa via a 1/8" port, it is replaced by the direct replacement SAU32X105S, which shares the exact body, force, and SC-series mounts.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace this model's legacy CS1-B/DS1-B switches, and adds an optional SAUF built-in-valve variant. Note that air cushions only decelerate; use a rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X105S 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 SAU32X105S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU32~50 Standard Cylinder SU32X105S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×105 | 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 SU32X105S Is Used
Small Part Ejection
Ideal for pushing lightweight molded components out of a fixture using a safe 241N working load over a 105mm travel distance.
Clamp Actuation
Compact profile body fits tight machine cells, delivering 345N pull force at 0.5MPa to secure small workpieces during machining.
Replacing the Airtac SU32~50 Standard Cylinder SU32X105S with the SAU32X105S
To replace this SU32X105S, order the SAU32X105S, confirming the 32mm bore, 105mm stroke, 1/8" port, M10x1.25 rod thread, and SC-series mounting. Because this SKU has the -S magnet, you must switch your legacy CS1-B/DS1-B switches to the SAU's CMSG/DMSG/EMSG sensors. If your application needs self-switching, explore the SAUF valve-integrated option. For sizing alternatives, a 40mm bore yields 628N push at 0.5MPa, whereas dropping pressure to 0.5MPa on this 32mm bore provides 402N. Remember, a standard cylinder drifts without live air; install an external pilot-operated check valve or rod lock to hold loads securely.
Replacement checklist
- ✓ Same bore / stroke → SAU32X105S
- ✓ 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 SU32X105S FAQ
Yes, the SU32X105S is discontinued. The direct replacement is the AirTAC SAU32X105S. It matches the 32mm bore, 105mm stroke, 402N force, 1/8" port, and SC-series mounting. You simply order the SAU32X105S as a direct fit.
The SAU32X105S delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and an 82kgf max at 1.0MPa. If your old SU32X105S used a -S magnet with CS1-B/DS1-B switches, you must upgrade to the current CMSG/DMSG/EMSG sensor family on the SAU replacement.
