This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X200STC, 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 SU50X200STC
The AirTAC SU32~50 Standard Cylinder SU50X200STC is a double-acting profile-type standard cylinder with a Ø50mm bore and 200mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X200STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X200STC
The AirTAC SU50X200STC is a discontinued double-acting profile-type cylinder with a 50mm bore and 200mm stroke. It delivers 982N push and 825N pull at 0.5MPa, with a 1/4" port. The direct replacement is the SAU50X200STC, matching the exact body, force, stroke, and TC mounting footprint.
When upgrading, note the SAU uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches. The SAU also adds a SAUF valve-integrated option the SU lacked.

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 SAU50X200STC 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 SU50X200STC Is Used
Package Diversion
Actuates routing gates on packaging lines using the 982N push force and 200mm stroke to redirect cartons efficiently.
Pallet Handling
Pushes lightweight pallets or totes into staging zones, benefiting from the compact profile body and TC mounting bracket.
Component Clamping
Secures workpieces during machining operations, utilizing the 825N pull force at 0.5MPa for reliable holding.
Replacing the Airtac SU32~50 Standard Cylinder SU50X200STC with the SAU50X200STC
To replace this SU50X200STC, order the SAU50X200STC. Verify your 1/4" port thread (PT/G/NPT), M16x1.5 rod end, and TC mounting accessory. Because this SKU has a magnet, you must switch from CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. If sizing alternatives, the adjacent 40mm bore yields 628N push at 0.5MPa, while the 63mm bore provides 1559N. For load holding, note a plain cylinder drifts without live air; use an external rod lock or pilot check valve. At 200mm stroke, ensure guide alignment to prevent rod bending. The SAUF variant adds a built-in valve if faster actuation is needed.
Replacement checklist
- ✓ Same bore / stroke → SAU50X200STC
- ✓ 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 SU50X200STC FAQ
Yes, the SU50X200STC is discontinued. The direct replacement is the AirTAC SAU50X200STC. It matches the 50mm bore, 200mm stroke, 982N force, 1/4" port, and TC mounting. The only change is the sensor family: you must use CMSG/DMSG/EMSG switches instead of the old CS1-B/DS1-B.
At 0.5MPa it provides 982N push and 825N pull. At 0.7MPa push is 1374N, and the theoretical max is 200kgf at 1.0MPa. Operating pressure is 0.15-1.0MPa, speed is 30-800mm/s, and temperature ranges from -20 to +70C. The 1/4" port and 21mm cushions are fixed by the 50mm bore.
