This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X1320STC, 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 SU50X1320STC
The AirTAC SU32~50 Standard Cylinder SU50X1320STC is a double-acting profile-type standard cylinder with a Ø50mm bore and 1320mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X1320STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X1320STC
The AirTAC SU50X1320STC is a discontinued double-acting profile-type cylinder with a 50mm bore and 1320mm stroke. Because 1320mm exceeds the 1200mm standard maximum for this bore, this unit is a non-standard, made-to-order configuration. It delivers a push force of 982 N at 0.5 MPa (pull 825 N) and features a 1/4" port, M16x1.5 rod thread, and 21mm adjustable air cushions. The direct replacement is the SAU50X1320STC, matching the bore, stroke, force, port, and SC-series mounting.
Two key upgrades exist in the SAU line: the legacy CS1-B/DS1-B switches used on this -S magnet model are replaced by current CMSG/DMSG/EMSG sensors, and the SAU introduces a SAUF variant with a built-in 4M solenoid valve that the SU series never offered. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore.

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 SAU50X1320STC 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 SU50X1320STC Is Used
Long-Reach Diversion
Pushes packages across a wide conveyor belt sorting line using the full 1320mm stroke, relying on the 982 N push force at 0.5 MPa to redirect heavy cartons smoothly.
High-Bay Extraction
Extracts pallets from deep storage racking where the 50mm bore provides adequate force, requiring an external guide to support the lengthy 1320mm rod extension.
Replacing the Airtac SU32~50 Standard Cylinder SU50X1320STC with the SAU50X1320STC
To replace this SU50X1320STC, order the SAU50X1320STC. Confirm the 50mm bore, 1320mm non-standard stroke, 1/4" port, M16x1.5 rod thread, and TC mounting interface. Because this -S SKU has a magnet, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. When sizing, a 40mm bore gives 628 N push at 0.5 MPa, while a 63mm bore yields 1559 N; this 50mm bore provides 982 N. A plain cylinder does not hold load without live air—the cushion only decelerates—so use an external rod lock or pilot-operated check valve for held loads. At 1320mm, the extended rod is highly susceptible to bending; use an external guide to prevent side-load damage. If you need self-switching, consider the SAUF built-in-valve option.
Replacement checklist
- ✓ Same bore / stroke → SAU50X1320STC
- ✓ 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 SU50X1320STC FAQ
Yes, the SU50X1320STC is discontinued. The direct replacement is the SAU50X1320STC. It matches the 50mm bore, 1320mm non-standard stroke, 1/4" port, output force, and SC-series TC mounting. The SAU body is a direct profile replacement.
The 50mm bore provides 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 this SU model has a -S magnet, it used legacy CS1-B/DS1-B switches; the SAU replacement requires current CMSG/DMSG/EMSG sensors.
