This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X1500STC, 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 SU50X1500STC
The AirTAC SU32~50 Standard Cylinder SU50X1500STC is a double-acting profile-type standard cylinder with a Ø50mm bore and 1500mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X1500STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X1500STC
The AirTAC SU50X1500STC is a discontinued double-acting profile-type cylinder with a 50mm bore and 1500mm stroke. Because 1500mm exceeds the 1200mm standard maximum for this bore, it is a non-standard, made-to-order unit. It delivered 982 N push force at 0.5 MPa through a 1/4" port. AirTAC replaced the SU line with the SAU family; the direct replacement is the SAU50X1500STC, matching the bore, stroke, force, port, and SC-series TC mounting.
The SAU upgrade retains the compact extruded aluminum body but modernizes the sensor groove. Your original -S magnet worked with legacy CS1-B/DS1-B switches, but the SAU replacement requires current CMSG/DMSG/EMSG sensors. The SAU line also introduces the SAUF variant with a built-in 4M solenoid valve, which the SU never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X1500STC 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 SAU50X1500STC 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 SU50X1500STC Is Used
Long-Reach Diversion
Pushes heavy packages across a wide 1500mm sorting belt using its 982N force, requiring external guides to prevent rod bending over the extended travel.
Material Transfer
Transfers workpieces between distant machine stations, utilizing the TC mount for rigid center-trunnion support during the 1500mm traverse.
Replacing the Airtac SU32~50 Standard Cylinder SU50X1500STC with the SAU50X1500STC
To replace the SU50X1500STC, order the SAU50X1500STC. Confirm the 50mm bore, 1500mm non-standard stroke, 1/4" port (default PT thread), M16x1.5 rod thread, and the TC mounting interface. Because this unit has an -S magnet, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the new SAU cylinder. If sizing alternatives, neighboring bores (40mm or 63mm) offer 628 N or 1559 N push at 0.5 MPa respectively. For load holding, remember a standard cylinder drifts without live air—the cushion only decelerates—so add an external rod lock or pilot-operated check valve if needed. Finally, at 1500mm stroke, the Ø20mm rod is vulnerable to bending; always use an external guide to prevent side-load damage.
Replacement checklist
- ✓ Same bore / stroke → SAU50X1500STC
- ✓ 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 SU50X1500STC FAQ
Yes, the SU50X1500STC is discontinued. The direct replacement is the SAU50X1500STC. It matches the 50mm bore, 1500mm stroke, 982N force, 1/4" port, and TC mounting. The main upgrade is that the SAU uses modern CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
This 50mm bore cylinder delivers 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 1500mm stroke is non-standard (exceeding the 1200mm max standard for this bore) and requires external guides to prevent rod bending.
