This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X150H, 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 SU40X150H
The AirTAC SU32~50 Standard Cylinder SU40X150H 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 SAU40X150H, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X150H
The AirTAC SU40X150H is a discontinued double-acting profile-type cylinder featuring a 40mm bore, 150mm stroke, and a Viton H high-temperature seal rated for 0 to 150 C. It delivers 628 N push force at 0.5 MPa through a 1/4 inch port. AirTAC replaced this unit with the SAU40X150H, a direct upgrade retaining the exact bore, stroke, output force, and SC-series mounting footprint.
Because this SKU lacks a magnet, it cannot accept a position switch. The SAU replacement also omits the magnet but introduces compatibility with modern CMSG/DMSG/EMSG sensors if you switch to a -S version, whereas the legacy SU used CS1-B/DS1-B switches. The SAU line also adds a SAUF valve-integrated variant the SU never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X150H 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 SAU40X150H 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 SU40X150H Is Used
High-Temp Ejection
Ideal for pushing molded parts out of heated zones up to 150 C using the Viton H seal, leveraging 628 N of thrust at 0.5 MPa.
Transfer Diversion
Acts as a compact 150mm stroke diverter on packaging lines, fitting neatly into existing SC-series mounting brackets without tie-rod interference.
Clamping Fixtures
Provides reliable clamping force for light machining or assembly holds, safely handling workloads up to 377 N without drifting under active air.
Replacing the Airtac SU32~50 Standard Cylinder SU40X150H with the SAU40X150H
To replace the SU40X150H, order the SAU40X150H. Verify your 1/4 inch port thread (PT, G, or NPT) and confirm your SC-series mounting hardware (LB, FA, FB, CA, CB, or TC) fits the identical profile body. If you need position sensing, you must move to an -S SKU; note that the SAU uses CMSG/DMSG/EMSG switches instead of the old CS1-B/DS1-B. Neighbouring bores offer different thrusts: a 32mm bore yields 402 N push at 0.5 MPa, while a 50mm bore yields 982 N. Since this is a 150mm stroke, ensure adequate guiding to prevent rod bending under side loads. A plain cylinder drifts on air loss—the cushion only decelerates—so install an external rod lock or pilot-operated check valve for load holding. The SAUF variant adds a built-in 4M solenoid valve if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU40X150H
- ✓ 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 SU40X150H FAQ
Yes, the AirTAC SU40X150H is discontinued. The direct replacement is the SAU40X150H. It shares the identical 40mm bore, 150mm stroke, 1/4 inch port, Viton H high-temp seal, and SC-series mounting, so it bolts right in.
It delivers 628 N push and 528 N pull at 0.5 MPa, 879 N push at 0.7 MPa, and a theoretical max of 128 kgf at 1.0 MPa. This specific SKU has no magnet (-S), so it cannot take a sensor; the SAU -S equivalent uses CMSG/DMSG/EMSG switches instead of the old CS1-B/DS1-B.
