This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X150STC, 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 SU40X150STC
The AirTAC SU32~50 Standard Cylinder SU40X150STC is a double-acting profile-type standard cylinder with a Ø40mm bore and 150mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X150STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X150STC
The AirTAC SU40X150STC is a discontinued double-acting profile-type cylinder with a 40mm bore and 150mm stroke. Delivering 628N push force at 0.5MPa, its extruded aluminum body is shorter than an ISO 15552 unit of the same bore. AirTAC replaced this unit with the SAU40X150STC, a direct upgrade retaining the exact 1/4" port, M12x1.25 rod thread, and SC-series TC mounting interface.
When migrating to the SAU40X150STC, the bore, stroke, and 628N output remain identical. Note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors, and the SAU line introduces a SAUF built-in-valve option the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X150STC carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAU40X150STC 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 SU40X150STC Is Used
Package Diverting
Pushes light cartons off a sorting line using 628N of thrust, with the 150mm stroke clearing the conveyor frame.
Pallet Stops
Acts as a pneumatic stop gate for low-profile pallets, dropping into the TC mount bracket for secure side framing.
Clamp Actuation
Drives a secondary clamping jaw on an assembly fixture, safely holding workloads near 377N during machining.
Replacing the Airtac SU32~50 Standard Cylinder SU40X150STC with the SAU40X150STC
To replace this SU40X150STC, order the SAU40X150STC. Verify your 1/4" port (PT/G/NPT) and SC-series TC mount are retained. Because this SKU includes the -S magnet, prepare to swap legacy CS1-B/DS1-B switches for current CMSG/DMSG/EMSG sensors. If you need higher force, the neighboring 50mm bore yields 982N push at 0.5MPa; if lower, the 32mm bore gives 402N. A plain cylinder drifts without live air—the 21mm cushions only decelerate, so add an external rod lock for vertical holding. For applications needing integrated control, explore the SAUF valve-cylinder variant.
Replacement checklist
- ✓ Same bore / stroke → SAU40X150STC
- ✓ 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 SU40X150STC FAQ
Yes, the SU40X150STC is end-of-life. The direct replacement is the SAU40X150STC. It matches the 40mm bore, 150mm stroke, 628N force, 1/4" port, and TC mounting, so it drops right into the same profile footprint.
At 0.5MPa it pushes 628N and pulls 528N; at 0.7MPa it pushes 879N, with a theoretical max of 128kgf at 1.0MPa. Because this is an -S magnet model, the old CS1-B/DS1-B switches do not fit the SAU replacement—you must upgrade to CMSG/DMSG/EMSG sensors.
