This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X250, 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 SU32X250
The AirTAC Airtac SU32~50 Standard Cylinder SU32X250 is a double-acting profile-type standard cylinder with a Ø32mm bore and 250mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X250, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X250
The AirTAC SU32X250 is a discontinued double-acting profile-type cylinder with a 32mm bore and 250mm stroke. It delivers 402N push and 345N pull at 0.5MPa through a 1/8" port. AirTAC replaced this unit with the SAU32X250, a direct upgrade retaining the exact bore, stroke, output force, port size, and SC-series mounting footprint.
The SAU replacement introduces CMSG/DMSG/EMSG sensors, superseding the legacy CS1-B/DS1-B switches, and adds an optional SAUF variant with a built-in 4M solenoid valve the SU line lacked. This non-magnetic SKU cannot accept a sensor.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X250 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 SAU32X250 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 SU32X250 Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to reliably push lightweight machined components out of a fixture across a 250mm travel distance.
Package Diverting
Actuates a routing gate on a 24V conveyor line, providing just enough stroke and force to redirect small cartons without overshooting.
Bin Push-Off
Cycles 250mm to clear small tote bins from a gravity roller conveyor, taking advantage of the compact 32mm profile body to fit tight frames.
Replacing the Airtac SU32~50 Standard Cylinder SU32X250 with the SAU32X250
To replace this SU32X250, order the SAU32X250. Verify your 1/8" port thread (PT, G, or NPT) and SC-series mounting (LB/FA/FB/CA/CB). Because this is a non-S SKU, it lacks a magnet and cannot hold a sensor; if sensing is needed, you must switch to an SAU32X250-S and adopt the new CMSG/DMSG/EMSG switch family. At 250mm stroke, prevent rod bending by guiding the load to avoid side-loading. Sizing both ways: if you need more force, the 40mm bore yields 628N push at 0.5MPa; if you need less, consider the 32mm bore's 345N pull capacity. Note that a plain cylinder does not hold load on air loss—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for suspended loads.
Replacement checklist
- ✓ Same bore / stroke → SAU32X250
- ✓ 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 SU32X250 FAQ
Yes, the AirTAC SU32X250 is discontinued and end-of-life. The direct replacement is the SAU32X250. It shares the same 32mm bore, 250mm stroke, 1/8" port, output force, and SC-series mounting accessories, so it fits the same application directly.
This double-acting cylinder provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical max of 82kgf at 1.0MPa. The adjustable air cushions only decelerate the piston near stroke end; they do not hold load. If power fails, the cylinder drifts, so use an external rod lock or pilot-operated check valve for suspended loads.
