This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X340, 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 SU32X340
The AirTAC Airtac SU32~50 Standard Cylinder SU32X340 is a double-acting profile-type standard cylinder with a Ø32mm bore and 340mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X340, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X340
The AirTAC SU32X340 is a discontinued double-acting profile-type cylinder with a 32mm bore and 340mm stroke. It delivers 402N push and 345N pull at 0.5MPa via a 1/8" port. AirTAC replaced it with the SAU32X340 direct replacement, matching the exact body, stroke, force, and SC-series mounts.
This compact extruded-aluminium barrel is shorter than an ISO 15552 equivalent. Note this non-magnetic SKU cannot take a sensor; the SAU upgrade uses CMSG/DMSG/EMSG switches and adds a SAUF valve-integrated option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X340 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 SAU32X340 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 SU32X340 Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to eject light machined components from a fixture, with the 340mm stroke clearing the work area completely.
Package Diverting
Deploys a 340mm arm to sort or divert small boxes on a line, where the compact 32mm profile saves space and the 1/8" port delivers rapid cycling.
Light-Duty Lift Gates
Raises lightweight access gates or stops using the 20kg vertical lift capacity, relying on external guides to support the long 340mm rod extension.
Replacing the Airtac SU32~50 Standard Cylinder SU32X340 with the SAU32X340
To replace the SU32X340, order the SAU32X340 direct equivalent, verifying the 1/8" port, M10x1.25 rod thread, and SC-series mounting. If downsizing from a 40mm bore, note the 40mm offers 628N push at 0.5MPa; if upsizing from a 32mm, the 40mm provides more force. For the 340mm stroke, use external guides to prevent rod bending and side-load wear. This non-magnetic SKU cannot accept a sensor; if sensing is needed, the SAU replacement requires CMSG/DMSG/EMSG switches. The cushion only decelerates; use an external rod lock or pilot-operated check valve to hold loads. The SAUF variant offers a built-in valve the SU lacked.
Replacement checklist
- ✓ Same bore / stroke → SAU32X340
- ✓ 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 SU32X340 FAQ
Yes, the SU32X340 is discontinued. The direct replacement is the AirTAC SAU32X340. It matches the 32mm bore, 340mm stroke, 402N push force at 0.5MPa, 1/8" port, and SC-series mounting accessories. You simply order the SAU equivalent.
It provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. This specific SKU lacks a magnet and cannot accept a sensor. If sensing is required, the SAU32X340 replacement supports CMSG/DMSG/EMSG switches.
