This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X127S, 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 SU50X127S
The AirTAC SU32~50 Standard Cylinder SU50X127S is a double-acting profile-type standard cylinder with a Ø50mm bore and 127mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X127S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X127S
The AirTAC SU50X127S is a discontinued double-acting profile-type cylinder with a 50mm bore and 127mm 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. The direct replacement is the SAU50X127S, matching the bore, stroke, force, and SC-series mounting.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace this unit's legacy CS1-B/DS1-B switches, and adds the SAUF built-in-valve option. Note that cushions only decelerate; use a rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X127S 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 SAU50X127S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU32~50 Standard Cylinder SU50X127S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 50 | Bore size in mm. |
| ×127 | Stroke length in mm. |
| -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 SU50X127S Is Used
Clamping Fixtures
Secures mid-weight machined parts during milling, utilizing the 982N push force at 0.5MPa for rigid, deflection-free holding.
Package Diverting
Actuates routing gates on packaging lines, where the 127mm stroke provides exact travel to redirect cartons without overshoot.
Pallet Stops
Controls pallet flow on low-profile accumulation conveyors, fitting easily into tight spaces due to the compact profile body.
Replacing the Airtac SU32~50 Standard Cylinder SU50X127S with the SAU50X127S
To replace this SU50X127S, order the SAU50X127S and verify the 1/4" port, M16x1.5 rod thread, and PT/G/NPT thread choice. Because this is an -S model, you must upgrade sensors from CS1-B/DS1-B to CMSG/DMSG/EMSG. If sizing alternatives, the 40mm bore yields 628N push at 0.5MPa, while the 63mm bore yields 1559N. For any load requiring pneumatic loss protection, add an external rod lock, as the cushion only decelerates. Since the 127mm stroke is under 300mm, rod bending is minimal, but ensure standard SC-series mounts are aligned.
Replacement checklist
- ✓ Same bore / stroke → SAU50X127S
- ✓ 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 SU50X127S FAQ
Yes, the AirTAC SU50X127S is discontinued. The direct replacement is the SAU50X127S. It shares the identical 50mm bore, 127mm stroke, 982N force, 1/4" port, and SC-series mounting, so it drops right into the same application.
At 0.5MPa it provides 982N push and 825N pull; 1374N push at 0.7MPa; 1767N at 0.9MPa; and a 200kgf maximum at 1.0MPa. Because this is an -S model, the legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG sensors on the SAU upgrade.
