This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X50S, 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 SU32X50S
The AirTAC Airtac SU32~50 Standard Cylinder SU32X50S is a double-acting profile-type standard cylinder with a Ø32mm bore and 50mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X50S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X50S
The AirTAC SU32X50S is a discontinued double-acting profile-type cylinder with a 32 mm bore and 50 mm stroke. AirTAC replaced this legacy unit with the SAU32X50S, a direct alternative retaining the exact 1/8" port, M10x1.25 rod thread, and SC-series mounting footprint.
Because this SKU includes a magnet (-S), it originally used CS1-B / DS1-B reed switches. The SAU successor transitions to modern CMSG / DMSG / EMSG electronic sensors. Furthermore, the SAU line introduces a SAUF variant featuring a built-in 4M solenoid valve for self-switching operation—an option the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X50S 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 SAU32X50S 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 SU32X50S Is Used
Small Part Ejection
Ideal for pushing lightweight molded components out of a fixture using a compact 32 mm profile body that saves valuable machine space.
Package Diverting
Provides the precise 50 mm stroke and 402 N force needed to deflect small cartons on a high-speed sorting conveyor line.
Bin Gate Actuation
Handles the short 50 mm movement required to open and close small gravity-feed bin gates in automated storage systems.
Replacing the Airtac SU32~50 Standard Cylinder SU32X50S with the SAU32X50S
To replace the SU32X50S, order the SAU32X50S, verifying the 50 mm stroke, 1/8" port, and default PT threads. If downsizing from a 40 mm bore, note the 40 mm class offers 628 N push at 0.5 MPa, whereas upsizing is required for heavier loads. The -S suffix means you must upgrade your legacy CS1-B / DS1-B switches to CMSG / DMSG / EMSG sensors. Remember, the 21 mm adjustable air cushions only decelerate the piston near stroke end; they do not hold loads. For vertical or safety-critical holding, install an external rod lock or pilot-operated check valve, as the cylinder will drift without live air pressure.
Replacement checklist
- ✓ Same bore / stroke → SAU32X50S
- ✓ 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 SU32X50S FAQ
Yes, the SU32X50S is discontinued. The direct replacement is the AirTAC SAU32X50S. It matches the 32 mm bore, 50 mm stroke, 1/8" port, output force, and SC-series mounting accessories. You simply order the SAU32X50S as a direct physical swap.
The cylinder provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical maximum of 82 kgf at 1.0 MPa. Because your old SU32X50S used a magnet with CS1-B / DS1-B switches, you must upgrade to CMSG / DMSG / EMSG sensors on the SAU replacement.
