This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X125H, 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 SU32X125H
The AirTAC SU32~50 Standard Cylinder SU32X125H is a double-acting profile-type standard cylinder with a Ø32mm bore and 125mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X125H, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X125H
The AirTAC SU32X125H is a discontinued double-acting profile-type cylinder with a 32 mm bore, 125 mm stroke, and Viton H high-temperature seals rated for 0 to 150 C. It delivers 402 N of push force at 0.5 MPa through a 1/8 inch port. AirTAC replaced this unit with the SAU32X125H, a direct alternative retaining the exact same body dimensions, output force, and SC-series mounting.
Because the barrel is an extruded aluminum profile rather than a tie-rod assembly, it is more compact than a standard ISO 15552 cylinder of the same bore. Note that this specific SKU lacks a magnet and cannot support sensing. Furthermore, the SAU upgrade family introduces a SAUF variant with a built-in 4M solenoid valve that the legacy SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X125H 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 SAU32X125H 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 SU32X125H Is Used
High-Temperature Ejection
Ideal for ejecting molded parts or operating doors near heat zones where Viton H seals survive 0-150 C environments without degrading.
Compact Part Clamping
Provides 402 N of clamping thrust at 0.5 MPa in tight machinery envelopes where the shorter profile body saves valuable space.
Replacing the Airtac SU32~50 Standard Cylinder SU32X125H with the SAU32X125H
To replace this discontinued SU32X125H, order the SAU32X125H, confirming the 32 mm bore, 125 mm stroke, 1/8 inch port, M10x1.25 rod thread, and Viton H high-temperature seals. Since this SKU has no -S magnet, it cannot accept a sensor; if you require position detection on the replacement, specify an SAU32X125HS and migrate to the current CMSG/DMSG/EMSG switch family, as the older CS1-B/DS1-B switches are obsolete. At 125 mm stroke, side-load and rod-bending risks are minimal, but always guide the load to prevent binding. If your application exceeds the 402 N push force at 0.5 MPa, step up to a 40 mm bore (628 N push); if you need less force, a smaller cylinder may suffice. For loads that must remain suspended during air loss, do not rely on the adjustable air cushions, as they only decelerate the piston near stroke end—install an external rod lock or pilot-operated check valve instead. The SAUF valve-integrated option is also available if you need self-switching functionality.
Replacement checklist
- ✓ Same bore / stroke → SAU32X125H
- ✓ 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 SU32X125H FAQ
Yes, the SU32X125H is discontinued. The direct replacement is the AirTAC SAU32X125H. It matches the 32 mm bore, 125 mm stroke, 1/8 inch port, Viton H high-temperature seals, and SC-series mounting accessories perfectly, requiring no mechanical modifications to install.
This double-acting cylinder delivers 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical maximum of 82 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept a sensor. If sensing is required on the SAU replacement, you must order the -S version and use CMSG/DMSG/EMSG switches, as the legacy CS1-B/DS1-B sensors are obsolete.
