This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X275S, 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 SU50X275S
The AirTAC SU32~50 Standard Cylinder SU50X275S is a double-acting profile-type standard cylinder with a Ø50mm bore and 275mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X275S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X275S
The AirTAC SU50X275S is a discontinued double-acting profile-type cylinder with a 50mm bore and 275mm stroke. It delivers 982N push force at 0.5MPa via a 1/4" port. AirTAC replaced it with the SAU50X275S, a direct alternative retaining the exact bore, stroke, output force, and SC-series mounting footprint.
Because the 275mm stroke exceeds 300mm? No, but at mid-length you still get compact extruded aluminum dimensions shorter than ISO 15552 equivalents. This -S SKU uses legacy CS1-B/DS1-B sensors, whereas the SAU successor upgrades to CMSG/DMSG/EMSG switches and introduces the SAUF built-in valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X275S 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 SAU50X275S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
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 SU50X275S Is Used
Package Diversion
Pushes medium-weight cartons off a sorting line using 982N thrust at 0.5MPa, with the 275mm stroke clearing guide rails easily.
Pallet Stop Gate
Acts as a pneumatic stop for incoming pallets, absorbing kinetic energy through the 21mm adjustable cushions at both ends.
Component Ejection
Ejects machined parts from a fixture, where the compact extruded profile saves space compared to older ISO standard bodies.
Replacing the Airtac SU32~50 Standard Cylinder SU50X275S with the SAU50X275S
To replace this cylinder, order the SAU50X275S. Verify your 1/4" port, M16x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB) stay identical. Because this has an -S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. For sizing both ways: a 40mm bore yields 628N [email protected], while a 63mm bore yields 1559N. The 275mm stroke is standard, but always support side loads to prevent rod bending. The air cushion only decelerates; for load holding on air loss, add an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAU50X275S
- ✓ 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 SU50X275S FAQ
Yes, the SU50X275S is discontinued. The direct replacement is the AirTAC SAU50X275S. It matches the 50mm bore, 275mm stroke, 1/4" port, force, and SC-series mounting. The main upgrade is that the -S magnet version switches from legacy CS1-B/DS1-B sensors to the modern CMSG/DMSG/EMSG family.
This double-acting cylinder uses a 1/4" port. It generates 982N push and 825N pull at 0.5MPa, 1374N push at 0.7MPa, and a theoretical maximum of 200kgf at 1.0MPa.
