This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X355, 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 SU50X355
The AirTAC Airtac SU32~50 Standard Cylinder SU50X355 is a double-acting profile-type standard cylinder with a Ø50mm bore and 355mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X355, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X355
The AirTAC SU50X355 is a discontinued double-acting profile-type cylinder with a 50mm bore and 355mm stroke. It delivers 982N push force at 0.5MPa via a 1/4" port. AirTAC replaced this unit with the SAU50X355, a direct alternative retaining the exact bore, stroke, output force, and SC-series mounting footprint.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches, and adds an optional SAUF built-in 4M valve the SU lacked. Note this SKU lacks a magnet and cannot accept switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X355 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 SAU50X355 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 SU50X355 Is Used
Package Diversion
Pushes medium-weight cartons off a conveyor line using the 982N push force, with the 355mm stroke clearing guide rails.
Pallet Indexing
Advances empty pallets into a loading zone where the compact profile body saves floor space compared to standard ISO cylinders.
Replacing the Airtac SU32~50 Standard Cylinder SU50X355 with the SAU50X355
To replace the SU50X355, order the SAU50X355 keeping the 50mm bore, 355mm stroke, 1/4" port, and M16x1.5 rod thread. Because this SKU lacks a magnet, it cannot accept position switches. If sensing is needed, specify an SAU-S model and migrate to CMSG/DMSG/EMSG sensors. For load holding, use an external rod lock or pilot-operated check valve, as cushions only decelerate. With a 355mm stroke, use external guides to prevent rod bending. If downsizing, a 40mm bore yields 628N; upsizing to 63mm provides 1559N at 0.5MPa.
Replacement checklist
- ✓ Same bore / stroke → SAU50X355
- ✓ 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 SU50X355 FAQ
Yes, the SU50X355 is discontinued. The direct replacement is the AirTAC SAU50X355. It shares the identical 50mm bore, 355mm stroke, 982N force, 1/4" port, and SC-series mounting accessories, so it fits the same application directly.
At 0.5MPa it provides 982N push and 825N pull; at 0.7MPa it pushes 1374N, with a theoretical max of 200kgf at 1.0MPa. This specific SKU lacks a magnet and cannot accept sensors. The SAU replacement uses CMSG/DMSG/EMSG switches if sensing is required.
