This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X375YN, 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 SU50X375YN
The AirTAC SU32~50 Standard Cylinder SU50X375YN is a double-acting profile-type standard cylinder with a Ø50mm bore and 375mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X375YN, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X375YN
The AirTAC SU50X375YN is a discontinued double-acting profile-type standard cylinder. It delivers 982 N push and 825 N pull at 0.5 MPa, utilizing a 50 mm bore, 375 mm stroke, and a 1/4" air port. AirTAC replaced this EOL unit with the SAU50X375YN, a direct upgrade retaining the exact bore, stroke, output force, port size, and SC-series mounting footprint.
Because this specific SKU lacks a magnet (-S), it cannot accept a magnetic piston switch. The SAU replacement also modernizes sensing to CMSG/DMSG/EMSG switches if you migrate to an -S version later, and introduces the SAUF built-in-valve variant the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X375YN 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 SAU50X375YN 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 SU50X375YN Is Used
Carton Diverter
Pushes light packaging off a main conveyor line using a 375 mm travel, relying on the 982 N push force to overcome friction.
Component Ejector
Cycles parts out of a machining fixture over 375 mm, needing external guide rails to prevent rod bending on extension.
Replacing the Airtac SU32~50 Standard Cylinder SU50X375YN with the SAU50X375YN
To replace this SU50X375YN, order the SAU50X375YN. Verify your 1/4" port thread (PT, G, or NPT), M16x1.5 rod-end thread, and SC-series mounting accessories (LB, FA, FB, CA, CB, TC). Since this is a non-magnet SKU, it cannot support sensors; if your application now requires position detection, step up to an SAU50X375YNS and adopt the current CMSG/DMSG/EMSG switch family. For the 375 mm stroke, prevent rod bending by guiding the load externally to absorb side-load forces. If checking neighbouring bores, a 40 mm bore yields 628 N push at 0.5 MPa, while a 63 mm bore provides 1559 N. Note that a standard cylinder drifts on air loss; for secure load holding during valve centering or pressure drops, install an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAU50X375YN
- ✓ 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 SU50X375YN FAQ
Yes, the SU50X375YN is discontinued. The direct replacement is the AirTAC SAU50X375YN. It matches the original 50 mm bore, 375 mm stroke, 982 N force, 1/4" port, and SC-series mounting, so it drops straight into the same application.
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa push is 1374 N, and the theoretical maximum is 200 kgf at 1.0 MPa. This specific SKU has no magnet (-S), so it cannot accept a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches if you order the -S version.
