This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X100STC, 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 SU32X100STC
The AirTAC Airtac SU32~50 Standard Cylinder SU32X100STC is a double-acting profile-type standard cylinder with a Ø32mm bore and 100mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X100STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X100STC
The AirTAC SU32X100STC is a discontinued double-acting profile-type cylinder with a 32mm bore and 100mm stroke. It delivers 402N push force at 0.5MPa via a 1/8" port. AirTAC replaced it with the SAU32X100STC, a direct upgrade retaining the exact body dimensions, force, and SC-series TC mounting interface.
Because the original featured a piston magnet (-S) for legacy CS1-B/DS1-B switches, upgrading to the SAU requires current CMSG/DMSG/EMSG sensors. The SAU line also introduces the SAUF built-in 4M solenoid valve variant, which the SU series lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X100STC 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 SAU32X100STC 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 SU32X100STC Is Used
Small Part Ejection
Ideal for pushing lightweight plastic or metal components out of a machining fixture using a safe 241N working load.
Package Diverting
Provides the precise 100mm stroke and compact profile needed to deflect small cartons on a high-speed sorting line.
Replacing the Airtac SU32~50 Standard Cylinder SU32X100STC with the SAU32X100STC
To replace this discontinued SU32X100STC, order the SAU32X100STC. Confirm the 1/8" port, M10x1.25 rod thread, and your TC mounting bracket. Since this SKU includes a magnet (-S), note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the new SAU block. If you need integrated flow control, consider the SAUF valve-integrated variant. For loads needing 563N at 0.7MPa, step up to a 40mm bore; if 345N pull force is excessive, drop to a smaller unit. Remember, a standard cylinder drifts without live air; use an external rod lock or pilot-operated check valve for secure load holding. At 100mm stroke, side-load is minimal, but always guide the rod to prevent premature seal wear.
Replacement checklist
- ✓ Same bore / stroke → SAU32X100STC
- ✓ 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 SU32X100STC FAQ
Yes, the SU32X100STC is discontinued. The direct replacement is the AirTAC SAU32X100STC. It shares the same 32mm bore, 100mm stroke, 402N push force at 0.5MPa, 1/8" port, and TC mounting interface, fitting the exact same application.
The bore delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. Because this model has a magnet (-S), it used legacy CS1-B/DS1-B switches; the SAU replacement requires upgrading to current CMSG/DMSG/EMSG sensors.
