This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X350SN, 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 SU32X350SN
The AirTAC SU32~50 Standard Cylinder SU32X350SN is a double-acting profile-type standard cylinder with a Ø32mm bore and 350mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X350SN, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X350SN
The AirTAC SU32X350SN is a discontinued double-acting profile-type cylinder with a 32mm bore and 350mm stroke. Delivering 402N push at 0.5MPa via a 1/8" port, it is replaced by the direct replacement SAU32X350SN, matching the force, stroke and SC-series mounts.
The SAU upgrade switches to CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B used here, and adds a SAUF valve-integrated option. The NBR seal suits -20 to +70C.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X350SN 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 SAU32X350SN 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 SU32X350SN Is Used
Package Diverting
Uses the 402N push force at 0.5MPa to push small cartons off a belt line, with the 350mm stroke covering the full lane width.
Small Part Ejection
Ejects lightweight molded parts from a press area, where the compact profile body saves space compared to standard ISO cylinders.
Gate Actuation
Cycles lightweight sorting gates in distribution hubs, relying on adjustable 21mm cushions to soften end-of-stroke impacts.
Replacing the Airtac SU32~50 Standard Cylinder SU32X350SN with the SAU32X350SN
To replace this SU32X350SN, order the SAU32X350SN direct: verify the 32mm bore, 350mm stroke, 1/8" port, M10x1.25 rod thread and SC mounting. The -S magnet means you must migrate from CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. For higher loads, neighbouring bores (40mm yields 628N push @0.5MPa) are options. The 350mm stroke requires an external guide to prevent rod bending. The plain cylinder drifts on air loss; use a rod lock for holding. Consider the SAUF for integrated valving.
Replacement checklist
- ✓ Same bore / stroke → SAU32X350SN
- ✓ 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 SU32X350SN FAQ
Yes, the SU32X350SN is discontinued. The direct replacement is the SAU32X350SN. It matches the 32mm bore, 350mm stroke, 402N force, 1/8" port and SC-series mounting. You just order the SAU equivalent.
It delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a max of 82kgf at 1.0MPa. The -S magnet works with legacy CS1-B/DS1-B switches; the SAU replacement uses CMSG/DMSG/EMSG sensors.
