This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X750STC, 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 SU32X750STC
The AirTAC SU32~50 Standard Cylinder SU32X750STC is a double-acting profile-type standard cylinder with a Ø32mm bore and 750mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X750STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X750STC
The AirTAC SU32X750STC is a discontinued double-acting profile-type cylinder with a 32 mm bore and 750 mm stroke. It delivers 402 N push force at 0.5 MPa through a 1/8" port. AirTAC replaced this end-of-life unit with the SAU32X750STC, a direct alternative retaining the exact bore, stroke, output force, port size and SC-series mounting footprint.
When upgrading, note that your -S magnet equipped this legacy cylinder for CS1-B/DS1-B switches, whereas the SAU replacement requires current CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve that the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X750STC 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 SAU32X750STC 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 SU32X750STC Is Used
Film Roll Transfer
Extends 750 mm to push empty plastic film cores into a loading cradle, relying on the adjustable 21 mm end cushions to decelerate the payload gently.
Replacing the Airtac SU32~50 Standard Cylinder SU32X750STC with the SAU32X750STC
To replace this discontinued SU32X750STC, order the SAU32X750STC. Verify your 1/8" port, M10x1.25 rod thread, TC mounting interface, and the sensor family change: your existing CS1-B/DS1-B switches will not fit the SAU, requiring CMSG/DMSG/EMSG equivalents. At 750 mm, this long stroke is susceptible to rod bending and side loads, so an external guide is recommended to prevent premature seal wear. If your application needs a larger bore, the 40 mm class provides 628 N push at 0.5 MPa; if smaller, confirm if a 25 mm stroke suffices. Remember that a standard cylinder drifts without live air; the 21 mm cushions only decelerate, so add an external rod lock or pilot-operated check valve for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU32X750STC
- ✓ 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 SU32X750STC FAQ
Yes, the SU32X750STC is end-of-life. The direct replacement is the AirTAC SAU32X750STC. It maintains the identical 32 mm bore, 750 mm stroke, 1/8" port, output force, and SC-series TC mounting. You simply order the SAU equivalent.
At 0.5 MPa it provides 402 N push and 345 N pull force, increasing to 563 N push at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa. Because this SKU includes a -S magnet, it used legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
