This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X170S, 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 SU50X170S
The AirTAC SU32~50 Standard Cylinder SU50X170S is a double-acting profile-type standard cylinder with a Ø50mm bore and 170mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X170S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X170S
The AirTAC SU50X170S is a discontinued double-acting profile-type cylinder with a 50mm bore and 170mm stroke. It delivers 982 N push force at 0.5 MPa via a 1/4" port. AirTAC replaced this unit with the SAU50X170S, a direct alternative retaining the exact bore, stroke, force, port size, and SC-series mounting footprint.
When upgrading, note the SAU replacement uses current CMSG/DMSG/EMSG sensors instead of this unit's legacy CS1-B/DS1-B switches, and the new SAUF variant offers a built-in valve the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X170S 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 SAU50X170S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
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 SU50X170S Is Used
Package Diverting
Pushes light-to-medium cartons off a sorting line using a 170mm stroke, relying on the 982 N push force to overcome friction.
Pallet Positioning
Indexes empty pallets into a wrapping station, where the compact profile body saves space compared to standard ISO units.
Clamp Actuation
Secures workpieces during machining by extending the 50mm bore rod to hold parts firmly under 1374 N of force at 0.7 MPa.
Replacing the Airtac SU32~50 Standard Cylinder SU50X170S with the SAU50X170S
To replace the SU50X170S, order the SAU50X170S and confirm the 1/4" port, M16x1.5 rod thread, and SC-series mounting. Because this SKU includes a magnet (-S), you must switch from the old CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG sensor family. If you need higher force, the 63mm bore provides 1559 N push at 0.5 MPa; if lower force suffices, the 40mm bore offers 628 N. Remember that a standard cylinder drifts without live air—the cushions only decelerate end-of-stroke motion—so install an external rod lock or pilot-operated check valve for secure load holding. The SAUF built-in-valve option is also available if you want to eliminate external plumbing.
Replacement checklist
- ✓ Same bore / stroke → SAU50X170S
- ✓ 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 SU50X170S FAQ
Yes, the SU50X170S is discontinued. The direct replacement is the SAU50X170S, which matches the 50mm bore, 170mm stroke, 1/4" port, and SC-series mounting. You must upgrade your sensors from the legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG switches.
The 50mm bore uses a 1/4" port. It generates 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a theoretical maximum of 200 kgf at 1.0 MPa. The cushions only decelerate the load and do not hold position without live air.
