This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X350S, 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 SU50X350S
The AirTAC SU32~50 Standard Cylinder SU50X350S 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 SAU50X350S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X350S
The AirTAC SU50X350S is a discontinued double-acting profile-type cylinder with a 50mm bore and 350mm stroke. Delivering 982 N of push force at 0.5 MPa, its extruded aluminum body is more compact than an ISO 15552 unit of the same size. AirTAC replaced this unit with the SAU50X350S, a direct upgrade retaining the exact 1/4" port, M16x1.5 rod thread, output force, and SC-series mounting compatibility.
The SAU upgrade introduces current CMSG/DMSG/EMSG sensors to replace this model's legacy CS1-B/DS1-B switches, and adds an optional SAUF built-in 4M solenoid valve variant the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X350S 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 SAU50X350S 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 SU50X350S Is Used
Package Diversion
Pushes medium-weight cartons at 982 N push force onto sorting lanes with a 350mm reach.
Pallet Handling
Actuates mid-stroke gating mechanisms where the 50mm bore provides ample 825 N pull force.
Component Ejection
Ejects machined parts from a fixture, using the 350mm stroke to clear the work area completely.
Replacing the Airtac SU32~50 Standard Cylinder SU50X350S with the SAU50X350S
To replace the SU50X350S, order the SAU50X350S. Verify your 1/4" port thread (PT, G, or NPT) and SC-series mounting hardware (LB, FA, FB, CA, CB, TC). Because this unit has the -S magnet, note that your legacy CS1-B/DS1-B switches must change to the CMSG/DMSG/EMSG family on the SAU. If your application needs the cylinder to hold a load without live air, the cushion only decelerates; you must add an external rod lock or pilot-operated check valve. For the 350mm stroke, use an external guide to prevent rod bending and side-load wear. If you need more force, the 63mm bore yields 1559 N push at 0.5 MPa; if less is required, the 40mm bore provides 628 N. The SAUF valve-integrated variant is available if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU50X350S
- ✓ 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 SU50X350S FAQ
Yes, the SU50X350S is discontinued. The direct replacement is the AirTAC SAU50X350S. It shares the same 50mm bore, 350mm stroke, 1/4" port, M16x1.5 rod thread, output force, and SC-series mounting accessories, so it fits the same application.
The SAU50X350S matches the SU force ratings: 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. Because your SU has the -S magnet, note that the legacy CS1-B/DS1-B switches are replaced by current CMSG/DMSG/EMSG sensors on the SAU.
