This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X50STC, 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 SU32X50STC
The AirTAC Airtac SU32~50 Standard Cylinder SU32X50STC is a double-acting profile-type standard cylinder with a Ø32mm bore and 50mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X50STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X50STC
The AirTAC SU32X50STC is a discontinued double-acting profile cylinder featuring a 32mm bore, 50mm stroke, and a TC mount interface. Delivering 402N push force at 0.5MPa, its extruded aluminum barrel is more compact than a standard ISO 15552 unit. AirTAC replaced this unit with the SAU32X50STC, a direct replacement retaining the exact bore, stroke, 1/8" port, and SC-series mounting.
Because the cushion only decelerates the piston near stroke end, this cylinder will not hold a load without live air—use an external rod lock for vertical holding. This -S SKU includes a magnet for legacy CS1-B/DS1-B switches; upgrading to the SAU requires switching to CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X50STC carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X50STC 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 SU32X50STC Is Used
Small Part Ejection
Ideal for pushing lightweight machined components out of a fixture using a safe 241N working load.
Package Diverting
Short 50mm stroke actuates a diverting gate on a compact packaging line where ISO cylinders are too long.
Pallet Stopper
Acts as a pneumatic stop for small pallets, benefiting from the TC mount and compact profile body.
Replacing the Airtac SU32~50 Standard Cylinder SU32X50STC with the SAU32X50STC
To replace the SU32X50STC, order the SAU32X50STC. Verify your 1/8" port threads (PT/G/NPT) and confirm the TC mounting accessory is reused. If downsizing from a 40mm bore, note the 40mm version offers 628N push at 0.5MPa versus this 32mm bore's 402N. The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, which the SU line lacked. For load holding, remember the air cushion only decelerates; add a pilot-operated check valve to prevent drift. Since this is a -S magnet model, you must replace legacy CS1-B/DS1-B switches with CMSG/DMSG/EMSG sensors.
Replacement checklist
- ✓ Same bore / stroke → SAU32X50STC
- ✓ 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 SU32X50STC FAQ
Yes, the AirTAC SU32X50STC is discontinued. The direct replacement is the SAU32X50STC. It matches the 32mm bore, 50mm stroke, 402N force, 1/8" port, and SC-series TC mounting. You simply order the SAU equivalent.
At 0.5MPa it provides 402N push and 345N pull force, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. This -S model has a magnet for legacy CS1-B/DS1-B switches; the SAU replacement requires upgrading to CMSG/DMSG/EMSG sensors.
