This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X700S, 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 SU32X700S
The AirTAC Airtac SU32~50 Standard Cylinder SU32X700S 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 SAU32X700S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X700S
The AirTAC SU32X700S is a discontinued double-acting profile-type cylinder with a 32 mm bore and 700 mm 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 unit with the SAU32X700S, a direct upgrade retaining the exact bore, stroke, force, port size, and SC-series mounting compatibility.
When migrating, note the SAU body uses current CMSG/DMSG/EMSG sensors, whereas this legacy -S magnet model relied on CS1-B/DS1-B switches. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve the SU lacked. Because the 700 mm stroke invites rod bending, use external guides to prevent side-load damage.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X700S 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 SAU32X700S 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 SU32X700S Is Used
Light-Part Ejection
Uses the 402 N push force at 0.5 MPa to sweep small molded components off a conveyor belt over the 700 mm travel distance.
Bin Diverting
Actuates a lightweight routing flap across a 700 mm span to sort small packages into chutes without requiring ISO 15552 bulk.
Sample Testing
Moves test probes across a 700 mm axis to contact delicate electronics, relying on adjustable 21 mm cushions for gentle end-of-stroke deceleration.
Replacing the Airtac SU32~50 Standard Cylinder SU32X700S with the SAU32X700S
To replace this SU32X700S, order the SAU32X700S direct equivalent, confirming the 32 mm bore, 700 mm stroke, M10x1.25 rod thread, 1/8" port, and SC-series mounting (LB/FA/FB/CA/CB/TC). If stepping up force, the 40 mm bore offers 628 N push at 0.5 MPa; stepping down is not advised for this length. The -S suffix means you must upgrade your legacy CS1-B/DS1-B switches to the SAU-compatible CMSG/DMSG/EMSG family. For the 700 mm stroke, add external guides to prevent rod bending under side loads. Note that a plain cylinder drifts on air loss—the cushions only decelerate—so fit an external rod lock or pilot-operated check valve if the load must be held. If self-switching is needed, explore the SAUF valve-integrated option.
Replacement checklist
- ✓ Same bore / stroke → SAU32X700S
- ✓ 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 SU32X700S FAQ
Yes, the SU32X700S is discontinued. The direct replacement is the AirTAC SAU32X700S. It shares the same 32 mm bore, 700 mm stroke, output force, 1/8" port, and SC-series mounting accessories, so it fits the same application directly.
This 32 mm bore cylinder 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 is an -S magnet model, it used legacy CS1-B/DS1-B switches; the SAU replacement requires upgrading to the current CMSG/DMSG/EMSG sensor family.
