This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X200STC, 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 SU32X200STC
The AirTAC SU32~50 Standard Cylinder SU32X200STC is a double-acting profile-type standard cylinder with a Ø32mm bore and 200mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X200STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X200STC
The AirTAC SU32X200STC is a discontinued double-acting profile-type cylinder with a 32 mm bore and 200 mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 unit of the same bore and delivers a push force of 402 N at 0.5 MPa. AirTAC replaced this end-of-life unit with the SAU32X200STC, a direct replacement retaining the exact bore, stroke, output force, 1/8" port, and SC-series TC mounting interface.
When upgrading, note that the SAU32X200STC uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches found on this -S magnet model. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve that the SU series lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X200STC 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 SAU32X200STC 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 SU32X200STC Is Used
Small Part Ejection
Uses the 402 N push force at 0.5 MPa to reliably push lightweight molded plastic components out of a machining fixture.
Package Diverting
Actuates a short 200 mm stroke diverter arm on a packaging line to sort small boxes without requiring ISO 15552 bulk.
Pallet Stopper Gate
Extends a 32 mm bore stopper blade to halt empty pallets on a roller conveyor, safely handling loads under 20 kg.
Replacing the Airtac SU32~50 Standard Cylinder SU32X200STC with the SAU32X200STC
To replace this discontinued SU32X200STC, order the SAU32X200STC direct equivalent, verifying the 32 mm bore, 200 mm stroke, 1/8" port, M10x1.25 rod thread, and TC mounting accessory. Because this model includes a magnet (-S), you must switch from the old CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG sensor family on the SAU. If your application needs higher force, the neighboring 40 mm bore provides 628 N push at 0.5 MPa; if less force is acceptable, there is no smaller standard profile bore in this series. For any stroke length of 200 mm or more, ensure adequate guide support to prevent rod bending and side-load damage. Remember that a standard cylinder does not hold load without live air—the 21 mm adjustable cushions only decelerate near stroke end—so add an external rod lock or pilot-operated check valve if you need static holding. The SAUF valve-integrated option can also simplify plumbing if you lack panel space.
Replacement checklist
- ✓ Same bore / stroke → SAU32X200STC
- ✓ 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 SU32X200STC FAQ
Yes, the SU32X200STC is discontinued. The direct replacement is the AirTAC SAU32X200STC. It matches the 32 mm bore, 200 mm stroke, 402 N force, 1/8" port, and SC-series TC mounting, so it fits the same application directly.
The 32 mm bore delivers a push of 402 N and pull of 345 N 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, the legacy CS1-B/DS1-B switches must be replaced by CMSG/DMSG/EMSG sensors on the new SAU unit.
