This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X190S, 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 SU32X190S
The AirTAC Airtac SU32~50 Standard Cylinder SU32X190S is a double-acting profile-type standard cylinder with a Ø32mm bore and 190mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X190S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X190S
The AirTAC SU32X190S is a discontinued double-acting profile-type cylinder with a 32mm bore and 190mm stroke. It delivers 402N push and 345N pull at 0.5MPa via a 1/8 port. AirTAC replaced this EOL unit with the SAU32X190S, a direct sharing the exact bore, stroke, force, port and SC-series mounting.
The compact extruded body is shorter than same-bore ISO cylinders. Note the -S magnet worked with legacy CS1-B/DS1-B switches, but the SAU replacement uses current CMSG/DMSG/EMSG sensors. The SAU line also adds a SAUF valve-integrated option the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X190S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X190S 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 SU32X190S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×190 | 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 SU32X190S Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to eject light molded components from an assembly fixture reliably.
Package Diverting
Actuates a routing gate on a packaging line, where the compact 32mm profile saves space.
Replacing the Airtac SU32~50 Standard Cylinder SU32X190S with the SAU32X190S
To replace this SU32X190S, order the SAU32X190S: confirm the 32mm bore, 190mm stroke, M10x1.25 rod thread, 1/8 port (PT/G/NPT) and SC-series mounting. Because it has the -S magnet, swap your legacy CS1-B/DS1-B switches for CMSG/DMSG/EMSG sensors. If sizing either way, the 40mm bore offers higher force, while the 32mm yields 563N at 0.7MPa. For loads needing hold on air loss, add an external rod lock, as cushions only decelerate. The SAUF variant integrates a valve if desired. At 190mm stroke, side-load risk is low, but ensure straight alignment to prevent rod bending.
Replacement checklist
- ✓ Same bore / stroke → SAU32X190S
- ✓ 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 SU32X190S FAQ
Yes, the SU32X190S is end-of-life. The direct replacement is the SAU32X190S. It shares the identical 32mm bore, 190mm stroke, 1/8 port, output force and SC-series mounting accessories, so it fits the same application directly.
At 0.5MPa it pushes 402N and pulls 345N; at 0.7MPa push is 563N, with a theoretical max of 82kgf at 1.0MPa. The -S suffix denotes a piston magnet for legacy CS1-B/DS1-B switches; when upgrading to the SAU replacement, you must use current CMSG/DMSG/EMSG sensors.
