This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X1400S, 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 SU50X1400S
The AirTAC SU32~50 Standard Cylinder SU50X1400S is a double-acting profile-type standard cylinder with a Ø50mm bore and 1400mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X1400S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X1400S
The AirTAC SU50X1400S is a discontinued double-acting profile-type cylinder with a 50 mm bore and 1400 mm stroke. Because 1400 mm exceeds the 1200 mm standard maximum for this bore, it is a non-standard, made-to-order length. It delivers 982 N push force at 0.5 MPa via a 1/4" port. AirTAC replaced the SU line with the SAU family; the direct replacement is the SAU50X1400S, matching the bore, stroke, output force, port size, and SC-series mounting.
The SAU upgrade introduces current CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used on this -S SKU, and adds the SAUF built-in-valve variant the SU line lacked. The extruded aluminium body is more compact than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X1400S 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 SAU50X1400S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU32~50 Standard Cylinder SU50X1400S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 50 | Bore size in mm. |
| ×1400 | Stroke length in mm. |
| -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 SU50X1400S Is Used
Long-Reach Diversion
Pushes heavy cartons across a wide conveyor belt over the full 1400 mm travel, relying on external guides to prevent rod bending.
Material Transfer
Transfers automotive components between distant workstations, using the compact profile body to save space in tight automated cells.
Replacing the Airtac SU32~50 Standard Cylinder SU50X1400S with the SAU50X1400S
To replace this SU50X1400S, order the SAU50X1400S direct equivalent, confirming the 50 mm bore, 1400 mm non-standard stroke, 1/4" port, M16x1.5 rod thread, and SC-series mounting. Because the -S magnet is present, note that the SAU requires CMSG/DMSG/EMSG sensors instead of the original CS1-B/DS1-B switches. For sizing alternatives, a 40 mm bore provides 628 N push at 0.5 MPa, while a 63 mm bore yields 1559 N. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot-operated check valve for held loads. At 1400 mm, prevent rod bending by guiding the load externally. If valve integration is needed, consider the SAUF variant.
Replacement checklist
- ✓ Same bore / stroke → SAU50X1400S
- ✓ 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 SU50X1400S FAQ
Yes, the SU50X1400S is discontinued. The direct replacement is the AirTAC SAU50X1400S. It provides identical bore, stroke, force, 1/4" port, and SC-series mounting compatibility. The SAU upgrade also offers the SAUF built-in-valve variant.
The 50 mm bore delivers 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a 200 kgf maximum at 1.0 MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG sensors on the SAU.
