This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X230, 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 SU32X230
The AirTAC Airtac SU32~50 Standard Cylinder SU32X230 is a double-acting profile-type standard cylinder with a Ø32mm bore and 230mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X230, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X230
The AirTAC SU32X230 is a discontinued double-acting profile-type cylinder featuring a 32 mm bore and 230 mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 cylinder of the same bore while sharing AirTAC SC-series mounting accessories. It delivers 402 N push force at 0.5 MPa and operates at speeds of 30-800 mm/s with a 1/8" port.
AirTAC replaced this end-of-life unit with the SAU32X230, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series mounting. The SAU upgrade introduces current CMSG/DMSG/EMSG sensors and a SAUF built-in 4M solenoid valve option the SU line lacked. Note this specific SKU lacks a magnet, so it cannot accept a sensor.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X230 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 SAU32X230 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 SU32X230 Is Used
Small Part Ejection
Ideal for pushing lightweight machined components out of a fixture using a safe 241 N working load.
Package Diverting
Sort small cartons on a line with a 230 mm stroke, benefiting from the compact 32 mm profile body.
Replacing the Airtac SU32~50 Standard Cylinder SU32X230 with the SAU32X230
To replace the discontinued SU32X230, order the SAU32X230 direct equivalent, confirming the 32 mm bore, 230 mm stroke, 1/8" port, and M10x1.25 rod thread. Because this SKU has no -S magnet, it cannot support sensing; if detection is needed, specify an SAU32X230-S and migrate to CMSG/DMSG/EMSG switches (the SU used legacy CS1-B/DS1-B). If you need higher force, the neighboring 40 mm bore provides 628 N push at 0.5 MPa. At 230 mm stroke, ensure adequate guiding to prevent rod bending under side loads. The cushion only decelerates the piston; for load holding on air loss, add an external rod lock or pilot-operated check valve. The SAUF variant offers a built-in valve if compact actuation is desired.
Replacement checklist
- ✓ Same bore / stroke → SAU32X230
- ✓ 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 SU32X230 FAQ
Yes, the SU32X230 is discontinued. The direct replacement is the SAU32X230. It shares the same 32 mm bore, 230 mm stroke, 402 N force, 1/8" port, and SC-series mounting, so it fits the same application directly.
It delivers 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical max of 82 kgf at 1.0 MPa. This specific SKU has no magnet and cannot take a sensor. If you need sensing, order the SAU32X230-S which uses current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
