This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X15S, 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 SU32X15S
The AirTAC SU32~50 Standard Cylinder SU32X15S is a double-acting profile-type standard cylinder with a Ø32mm bore and 15mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X15S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X15S
The AirTAC SU32X15S is a discontinued double-acting profile-type cylinder featuring a 32mm bore and 15mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 cylinder of the same bore and delivers 402N push force at 0.5MPa. The direct replacement is the SAU32X15S, matching the bore, stroke, force, 1/8" port, and SC-series mounting.
This -S SKU includes a piston magnet for legacy CS1-B/DS1-B switches; upgrading to the SAU requires current CMSG/DMSG/EMSG sensors. The SAU line also introduces the SAUF built-in 4M solenoid valve option, which the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X15S 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 SAU32X15S 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 SU32X15S Is Used
Small Part Ejection
Uses the 15mm short stroke and 402N push at 0.5MPa to eject small molded components from a fixture quickly without occupying much machine footprint.
Valve Actuation
Ideal for pneumatically toggling small process valves or diverters where a compact 32mm profile body and precise short movement are required.
Replacing the Airtac SU32~50 Standard Cylinder SU32X15S with the SAU32X15S
To replace this SU32X15S, order the SAU32X15S, confirming the 1/8" port, M10x1.25 rod thread, and SC-series mounting. Because this 15mm stroke is nonstandard, verify exact lead times. The -S magnet means you must switch from CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. For loads needing holding on air loss, add an external rod lock, as cushions only decelerate. Neighboring 40mm bore yields 628N push at 0.5MPa if more force is needed. The SAUF valve-integrated variant is an option for self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU32X15S
- ✓ 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 SU32X15S FAQ
Yes, the SU32X15S is discontinued. The direct replacement is the SAU32X15S, offering the same 32mm bore, 15mm stroke, force, 1/8" port, and SC-series mounting compatibility.
It delivers 402N push and 345N pull at 0.5MPa, 563N at 0.7MPa, and an 82kgf max at 1.0MPa. The -S magnet works with legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
