This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X145S, 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 SU32X145S
The AirTAC Airtac SU32~50 Standard Cylinder SU32X145S is a double-acting profile-type standard cylinder with a Ø32mm bore and 145mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X145S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X145S
The AirTAC SU32X145S is a discontinued double-acting profile cylinder with a 32mm bore and 145mm stroke. Delivering 402N push at 0.5MPa, it features an extruded aluminum barrel that is more compact than an ISO 15552 cylinder of the same size. AirTAC replaced this end-of-life unit with the SAU32X145S, a direct upgrade retaining the exact bore, stroke, force, 1/8" port, and SC-series mounting.
The SAU replacement introduces CMSG/DMSG/EMSG sensors, superseding the legacy CS1-B/DS1-B switches used on this -S model, and adds an optional SAUF built-in 4M valve. Note that air cushions only decelerate; use an external rod lock to hold loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X145S 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 SAU32X145S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
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 SU32X145S Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to reliably knock lightweight molded parts out of a machining fixture.
Package Routing
Actuates a diverting arm on a packaging line, where the 145mm stroke provides just enough travel to redirect small cartons.
Bin Sorting
Pushes selected items into gravity chutes, leveraging the compact profile to fit within tight automated storage frames.
Replacing the Airtac SU32~50 Standard Cylinder SU32X145S with the SAU32X145S
To replace the SU32X145S, order the SAU32X145S. Verify your 1/8" port, M10x1.25 rod thread, and SC-series mounting. Because this SKU has the -S magnet, you must upgrade to CMSG/DMSG/EMSG switches; the old CS1-B/DS1-B sensors will not fit the new groove. If dropping down to a 25mm bore saves space, expect lower force, while a 40mm bore yields 628N push at 0.5MPa. At 145mm stroke, side-load is minimal, but always guide the rod to prevent bending. For load holding on air loss, add a pilot-operated check valve, as cushions only decelerate. If you need self-switching, explore the SAUF valve-integrated variant.
Replacement checklist
- ✓ Same bore / stroke → SAU32X145S
- ✓ 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 SU32X145S FAQ
Yes, the SU32X145S is discontinued. The direct replacement is the SAU32X145S. It shares the same 32mm bore, 145mm stroke, output force, 1/8" port, and SC-series mounting accessories, but requires CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The 32mm bore has a 1/8" port. It delivers 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 piston rod is 12mm with an M10x1.25 thread.
