This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X25TC, 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 SU50X25TC
The AirTAC SU32~50 Standard Cylinder SU50X25TC is a double-acting profile-type standard cylinder with a Ø50mm bore and 25mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X25TC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X25TC
The AirTAC SU50X25TC is a discontinued double-acting profile-type cylinder with a 50mm bore and 25mm stroke. Delivering 982N push force at 0.5MPa via a 1/4" port, its extruded aluminum body is more compact than an ISO 15552 unit. AirTAC replaced it with the SAU50X25TC direct replacement, matching the exact bore, stroke, output force, port size, and SC-series TC mounting.
When upgrading, note the SAU uses current CMSG/DMSG/EMSG sensors, whereas this legacy SU used CS1-B/DS1-B switches. This specific SKU lacks a magnet, so it cannot accept any sensor. The SAU family also adds a SAUF built-in-valve option the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X25TC 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 SAU50X25TC 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 SU50X25TC Is Used
Short-Stroke Clamping
Ideal for holding parts during machining, using the 982N push force at 0.5MPa across a 25mm travel distance.
Package Diverting
Provides rapid 25mm actuation at 30-800mm/s to push lightweight cartons off a production line via the TC mount.
Stopper Gate
Acts as a compact pneumatic stop in material handling systems, lifting or extending 25mm to halt pallet movement.
Replacing the Airtac SU32~50 Standard Cylinder SU50X25TC with the SAU50X25TC
To replace this SU50X25TC, order the SAU50X25TC with the identical 50mm bore, 25mm stroke, M16x1.5 rod thread, 1/4" port, and TC mounting. Because this SKU has no magnet (-S), it cannot support sensing; if you need position detection on the new unit, specify an SAU50X25TC-S and use CMSG/DMSG/EMSG switches. If you need higher force, the 63mm bore offers 1559N push at 0.5MPa; for tighter spaces, the 40mm bore provides 628N. Remember, a standard cylinder drifts without live air—the 21mm cushions only decelerate the piston near stroke end, so add an external rod lock or pilot-operated check valve for load holding. The SAUF variant integrates a 4M solenoid valve if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU50X25TC
- ✓ 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 SU50X25TC FAQ
Yes, the SU50X25TC is discontinued. The direct replacement is the AirTAC SAU50X25TC. It shares the identical 50mm bore, 25mm stroke, 1/4" port, and TC mounting, so it drops right into the same application.
At 0.5MPa it pushes 982N and pulls 825N; at 0.7MPa it pushes 1374N, with a theoretical max of 200kgf at 1.0MPa. This specific SKU lacks a magnet and cannot take a sensor. If you need detection on the SAU replacement, order the -S version and use CMSG/DMSG/EMSG switches.
