This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X700STC, 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 SU32X700STC
The AirTAC Airtac SU32~50 Standard Cylinder SU32X700STC is a double-acting profile-type standard cylinder with a Ø32mm bore and 700mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X700STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X700STC
The AirTAC SU32X700STC is a discontinued double-acting profile-type cylinder with a 32mm bore and 700mm stroke. It delivers 402 N push and 345 N pull at 0.5 MPa, operating at 30-800 mm/s through a 1/8" port. AirTAC replaced this legacy unit with the SAU32X700STC, a direct sharing the exact bore, stroke, output force, port size, and SC-series TC mounting interface.
The SAU upgrade switches the legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors, and introduces the SAUF built-in 4M solenoid valve variant. Note that a plain cylinder drifts on air loss; the 21 mm cushions only decelerate near stroke ends, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X700STC 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 SAU32X700STC 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 SU32X700STC Is Used
Vertical Material Lift
Raises 20 kg tote boxes through a 700 mm travel distance, requiring external guides to prevent rod bending on the 32 mm bore.
Compact Ejection
Ejects small machined parts from a fixture where the shorter profile body saves space compared to standard ISO cylinders.
Replacing the Airtac SU32~50 Standard Cylinder SU32X700STC with the SAU32X700STC
To replace the SU32X700STC, order the SAU32X700STC and verify your 1/8" port, M10x1.25 rod thread, and TC mounting accessory. Because this SKU includes the -S magnet, you must upgrade your legacy CS1-B/DS1-B switches to the SAU-compatible CMSG/DMSG/EMSG family. For the 700mm stroke, external guides are strongly recommended to prevent rod bending under side loads. If you need more force, the neighbouring 40mm bore offers 628 N push at 0.5 MPa. The air cushion only decelerates the piston; it does not hold the load, so add a pilot-operated check valve for vertical applications. If you want to simplify plumbing, the SAUF variant integrates a 4M solenoid valve directly on the body.
Replacement checklist
- ✓ Same bore / stroke → SAU32X700STC
- ✓ 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 SU32X700STC FAQ
Yes, the SU32X700STC is discontinued. The direct replacement is the AirTAC SAU32X700STC. It shares the identical 32mm bore, 700mm stroke, 402 N force at 0.5 MPa, 1/8" port, and TC mounting, so it drops into the same application.
The 32mm 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 has the -S magnet, it used legacy CS1-B/DS1-B switches; the SAU replacement requires the newer CMSG/DMSG/EMSG sensor family.
