This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X150STC, 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 SU32X150STC
The AirTAC Airtac SU32~50 Standard Cylinder SU32X150STC is a double-acting profile-type standard cylinder with a Ø32mm bore and 150mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X150STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X150STC
The AirTAC SU32X150STC is a discontinued double-acting profile cylinder with a 32mm bore and 150mm stroke. Delivering 402N push force at 0.5MPa, it features a compact extruded aluminum body shorter than an ISO 15552 equivalent. AirTAC replaced it with the direct replacement SAU32X150STC, matching the bore, stroke, 1/8" port, and SC-series TC 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 adds a SAUF valve-integrated variant. Note that standard cylinders drift without air; use a rod lock for holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X150STC 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 SAU32X150STC 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 SU32X150STC Is Used
Small Part Ejection
Ideal for pushing lightweight machined components out of a fixture using a safe 241N working load.
Package Diverting
Actuates a short 150mm stroke diverter arm on a packaging line to route small cartons laterally.
Stopper Gate Control
Raises and lowers a pneumatic stop gate to regulate item flow on a compact material handling conveyor.
Replacing the Airtac SU32~50 Standard Cylinder SU32X150STC with the SAU32X150STC
To replace this SU32X150STC, order the SAU32X150STC. Verify the 32mm bore, 150mm stroke, 1/8" port (default PT), M10x1.25 rod thread, and TC mounting. Because this has the -S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. If you need higher force, the neighboring 40mm bore yields 628N push at 0.5MPa; if smaller, bores below 32mm are unavailable. At 150mm stroke, side-load risks are low, but always guide the load. A plain cylinder does not hold load without air; add an external rod lock or pilot-operated check valve for vertical holding. The SAUF variant offers a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU32X150STC
- ✓ 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 SU32X150STC FAQ
Yes, the SU32X150STC is discontinued. The direct replacement is the AirTAC SAU32X150STC. It shares the identical 32mm bore, 150mm stroke, output force, 1/8" port, and TC mounting interface, so it fits the same application.
It delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. The -S magnet on this SU works with legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
