This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X175SN, 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 SU50X175SN
The AirTAC SU32~50 Standard Cylinder SU50X175SN is a double-acting profile-type standard cylinder with a Ø50mm bore and 175mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X175SN, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X175SN
The AirTAC SU50X175SN is a discontinued double-acting profile-type cylinder with a 50mm bore and 175mm stroke. Built with an extruded aluminum barrel, it is shorter and more compact than an ISO 15552 cylinder of the same bore.
AirTAC replaced this EOL unit with the SAU50X175SN, a direct replacement retaining the exact 50mm bore, 175mm stroke, 1/4" port, M16x1.5 rod thread, and SC-series mounting. The SAU upgrade introduces current CMSG/DMSG/EMSG sensors to replace this model's legacy CS1-B/DS1-B switches, and adds the SAUF built-in 4M solenoid valve option the SU line lacked. The -N NBR seal supports standard -20 to +70 C temperatures, while a Viton H option raises this to 150 C.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X175SN 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 SAU50X175SN 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 SU50X175SN Is Used
Package Diverting
Actuates routing gates on 50 kg class conveyor lines, using the 175mm stroke to push cartons cleanly into sorting lanes without overshooting.
Pallet Lift Stops
Deploys mechanical stops at palletizer stations; the 982 N push force at 0.5 MPa reliably halts inbound pallets while awaiting the next transfer.
Clamp Actuation
Drives mid-force clamping fixtures for machining or welding, where the compact profile barrel saves space and the NBR seals handle standard shop heat.
Replacing the Airtac SU32~50 Standard Cylinder SU50X175SN with the SAU50X175SN
To replace the SU50X175SN, order the SAU50X175SN. Verify your 1/4" port (PT/G/NPT), M16x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB) to ensure a direct fit. Because this SKU includes the -S magnet, you must upgrade your legacy CS1-B/DS1-B switches to the SAU-compatible CMSG/DMSG/EMSG sensor family. If sizing neighbors, a 40mm bore offers 628 N push at 0.5 MPa, while a 63mm bore provides 1559 N. For load holding, note that a plain cylinder drifts without live air—the 21mm adjustable cushions only decelerate near stroke end—so install an external rod lock or pilot-operated check valve for suspended loads. If you need self-switching, explore the SAUF valve-integrated variant.
Replacement checklist
- ✓ Same bore / stroke → SAU50X175SN
- ✓ 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 SU50X175SN FAQ
Yes, the SU50X175SN is discontinued. The direct replacement is the SAU50X175SN. It matches the 50mm bore, 175mm stroke, 982 N push force at 0.5 MPa, 1/4" port, and SC-series mounting. You simply order the SAU equivalent.
At 0.5 MPa it pushes 982 N and pulls 825 N; at 0.7 MPa it pushes 1374 N, with a theoretical max of 200 kgf at 1.0 MPa. The 1/4" port is fixed by the bore. Because this SKU has a magnet (-S), it used legacy CS1-B/DS1-B switches; the SAU replacement requires current CMSG/DMSG/EMSG sensors.
