This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X240, 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 SU32X240
The AirTAC Airtac SU32~50 Standard Cylinder SU32X240 is a double-acting profile-type standard cylinder with a Ø32mm bore and 240mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X240, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X240
The AirTAC SU32X240 is a discontinued double-acting profile cylinder with a 32 mm bore and 240 mm stroke. It delivers 402 N push force at 0.5 MPa through a 1/8" port. The direct replacement is the SAU32X240, matching the body, stroke, force, port and SC-series mounting.
This compact extruded-aluminium body is shorter than an ISO 15552 equivalent. Since this SKU lacks a magnet, it cannot accept a sensor; the SAU upgrade switches to CMSG/DMSG/EMSG switches and adds a SAUF valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X240 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 SAU32X240 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 SU32X240 Is Used
Small Part Ejection
Uses the 402 N push at 0.5 MPa to reliably knock light finished components out of a machining fixture.
Package Diverting
Actuates a routing gate on a conveyor line, where the compact 32 mm profile saves space.
Replacing the Airtac SU32~50 Standard Cylinder SU32X240 with the SAU32X240
To replace this SU32X240, order the SAU32X240 with the same 32 mm bore, 240 mm stroke, 1/8" port, M10x1.25 rod thread and SC-series mounts. Being a non-magnet SKU, it cannot take a sensor; if sensing is needed, specify an -S SAU and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For higher loads, a 40 mm bore gives 628 N push at 0.5 MPa. A plain cylinder drifts on air loss, so use an external rod lock for holding. The 240 mm stroke is under the 1000 mm limit, but ensure guide alignment to prevent rod bending.
Replacement checklist
- ✓ Same bore / stroke → SAU32X240
- ✓ 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 SU32X240 FAQ
Yes, the SU32X240 is discontinued. The direct replacement is the SAU32X240. It shares the same 32 mm bore, 240 mm stroke, 402 N output force, 1/8" port and SC-series mounting accessories.
It provides 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. The air cushion only decelerates the piston; it does not hold the load on air loss, so you need an external rod lock or pilot-operated check valve for holding.
