This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X45, 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 SU32X45
The AirTAC Airtac SU32~50 Standard Cylinder SU32X45 is a double-acting profile-type standard cylinder with a Ø32mm bore and 45mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X45, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X45
The AirTAC SU32X45 is a discontinued double-acting profile-type cylinder with a 32mm bore and 45mm stroke. Delivering 402N push and 345N pull at 0.5MPa, it uses a 1/8" port and M10x1.25 rod thread. AirTAC replaced this unit with the SAU32X45, a direct alternative retaining the exact bore, stroke, output force, port size, and SC-series mounting.
This compact extruded-aluminium body is shorter than an ISO 15552 equivalent. As a non-magnet SKU, it cannot accept switches. The SAU upgrade switches to CMSG/DMSG/EMSG sensors and adds the SAUF built-in-valve option the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X45 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 SAU32X45 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 SU32X45 Is Used
Small Part Ejection
Ideal for pushing lightweight finished parts out of a machining fixture using a short 45mm stroke and 402N force at 0.5MPa.
Package Diverting
Actuates a short diverter arm on a packaging line, where the compact profile saves space and the 1/8" port provides ample flow.
Component Sorting
Sorts small electronic or plastic components, providing reliable 345N pull force to retract a gating mechanism at 30-800mm/s.
Replacing the Airtac SU32~50 Standard Cylinder SU32X45 with the SAU32X45
To replace the SU32X45, order the SAU32X45 direct equivalent. Verify your 1/8" port thread (PT/G/NPT), M10x1.25 rod end, and SC-series mounting (LB/FA/FB/CA/CB). Because this is a no-S SKU, it has no magnet and cannot take a sensor; if you require position detection on the SAU, order an -S model and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For sizing both ways: a 40mm bore yields 628N push at 0.5MPa, while dropping to a 25mm bore reduces force. Note that a plain cylinder drifts on air loss—the 21mm cushions only decelerate near stroke ends, so use an external rod lock or pilot-operated check valve for held loads. The 45mm stroke is well under the 32mm bore's 1000mm max, so side-load bending is minimal, but always guide the load.
Replacement checklist
- ✓ Same bore / stroke → SAU32X45
- ✓ 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 SU32X45 FAQ
Yes, the AirTAC SU32X45 is discontinued. The direct replacement is the SAU32X45. It matches the 32mm bore, 45mm stroke, 402N force, 1/8" port, and SC-series mounting. You simply order the SAU32X45 to swap it out.
It delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. Because this specific SKU lacks a magnet (-S), it cannot accept sensors. If sensing is needed on the SAU replacement, you must order an -S version which uses CMSG/DMSG/EMSG switches.
