This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X350SN, 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 SU50X350SN
The AirTAC SU32~50 Standard Cylinder SU50X350SN is a double-acting profile-type standard cylinder with a Ø50mm bore and 350mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X350SN, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X350SN
The AirTAC SU50X350SN is a discontinued double-acting profile-type cylinder with a 50mm bore and 350mm stroke. It features an extruded aluminum barrel making it more compact than an ISO 15552 cylinder of the same bore, delivering 982 N push force at 0.5 MPa. The direct replacement is the SAU50X350SN, matching the bore, stroke, 1/4" port, M16x1.5 rod thread, and SC-series mounting.
This SU model includes a piston magnet for legacy CS1-B/DS1-B switches; upgrading to the SAU requires switching to current CMSG/DMSG/EMSG sensors. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve, an option the original SU line lacked. The -N suffix indicates NBR seals, and the air cushions only decelerate the piston without locking the load.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X350SN carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAU50X350SN 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 SU50X350SN Is Used
Package Diverting
Pushes medium-weight cartons off a sorting line using the 982 N push force at 0.5 MPa over the 350mm travel distance.
Pallet Stopper Gate
Acts as a pneumatic stop for standard pallets, with the 50 kg vertical lift capacity easily handling gate weight.
Component Ejection
Ejects machined parts from a fixture, relying on adjustable 21mm cushions to decelerate the tooling at stroke end.
Replacing the Airtac SU32~50 Standard Cylinder SU50X350SN with the SAU50X350SN
To replace this discontinued SU50X350SN, order the SAU50X350SN. Confirm the 50mm bore, 350mm stroke, 1/4" port with PT threads, and SC-series mounting hardware are retained. Because this SKU has a magnet (-S), note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the new SAU cylinder. The -N denotes NBR seals suitable for standard -20 to +70 C environments; for 150 C operations specify Viton H. If you need self-switching, consider the SAUF valve-integrated variant. For loads requiring holding on air loss, add an external rod lock or pilot-operated check valve, as the cushions only decelerate. At 350mm, prevent rod bending by guiding the load externally. If downsizing, a 40mm bore yields 628 N push at 0.5 MPa; if upsizing, a 63mm bore provides 1559 N.
Replacement checklist
- ✓ Same bore / stroke → SAU50X350SN
- ✓ 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 SU50X350SN FAQ
Yes, the SU50X350SN is discontinued. The direct replacement is the AirTAC SAU50X350SN. It matches the 50mm bore, 350mm stroke, 1/4" port, output force, and SC-series mounting. You just order the SAU equivalent.
The 50mm bore delivers 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a theoretical max of 200 kgf at 1.0 MPa. This SU model uses legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
