This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X65STC, 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 SU50X65STC
The AirTAC Airtac SU32~50 Standard Cylinder SU50X65STC is a double-acting profile-type standard cylinder with a Ø50mm bore and 65mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X65STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X65STC
The AirTAC SU50X65STC is a discontinued double-acting profile-type cylinder with a 50mm bore and 65mm stroke. It delivers 982N push force at 0.5MPa. AirTAC replaced this end-of-life unit with the SAU50X65STC, a direct upgrade retaining the exact bore, stroke, 1/4" port, and SC-series TC mounting interface.
Because the 65mm stroke is non-standard, the SAU replacement is built to order. The upgrade introduces CMSG/DMSG/EMSG sensors to replace the legacy CS1-B/DS1-B switches used on this -S magnet model, and adds the new SAUF built-in-valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X65STC 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 SAU50X65STC 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 SU50X65STC Is Used
Clamp and Release Station
Ideal for securing mid-weight workpieces during machining, using the 982N push force to hold parts firmly against a fixture before releasing them for transfer.
Package Diverting Gate
Drives a short-stroke routing flap on a packaging line, leveraging the compact 65mm stroke and TC mount to fit within tight conveyor frame clearances.
Vertical Lift Stopper
Acts as a pneumatic stop or lift pin in a material handling rack, safely managing vertical loads up to 50kg when paired with a pilot-operated check valve.
Replacing the Airtac SU32~50 Standard Cylinder SU50X65STC with the SAU50X65STC
To replace this discontinued SU50X65STC, order the SAU50X65STC, confirming the 50mm bore, 65mm non-standard stroke, M16x1.5 rod thread, 1/4" port, and TC mounting. The built-in magnet means your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. If you need higher force, the neighbouring 63mm bore provides 1559N push at 0.5MPa; if less is required, the 40mm bore offers 628N. A plain cylinder drifts without live air—the cushion only decelerates—so fit 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 → SAU50X65STC
- ✓ 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 SU50X65STC FAQ
Yes, the AirTAC SU50X65STC is discontinued. The direct replacement is the SAU50X65STC. It shares the same 50mm bore, 65mm stroke, 1/4" port, output force, and SC-series TC mounting accessories, so it fits the same application directly.
At 0.5MPa it provides 982N push and 825N pull force, 1374N push at 0.7MPa, and a theoretical max of 200kgf at 1.0MPa. Because this SKU includes a magnet (-S), it used legacy CS1-B/DS1-B switches; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
