This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X10, 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 SU40X10
The AirTAC Airtac SU32~50 Standard Cylinder SU40X10 is a double-acting profile-type standard cylinder with a Ø40mm bore and 10mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X10, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X10
The AirTAC SU40X10 is a discontinued double-acting profile-type cylinder featuring a 40mm bore and 10mm stroke. It delivers 628N push force at 0.5MPa via a 1/4" port, utilizing an extruded aluminum barrel that is more compact than an ISO 15552 cylinder of the same size. AirTAC replaced this unit with the SAU40X10 direct replacement, maintaining the exact body dimensions, force, and SC-series mounting compatibility.
The SAU40X10 upgrade introduces current CMSG/DMSG/EMSG sensors (the legacy SU used CS1-B/DS1-B switches) and adds the SAUF built-in 4M solenoid valve option. Note that this specific SKU lacks a magnet, so it cannot accept a magnetic sensor.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X10 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 SAU40X10 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 SU40X10 Is Used
Short-Stroke Clamping
Ideal for holding lightweight components in machining or assembly fixtures using its 628N push force over a fast 10mm travel.
Ejector Mechanisms
Provides a compact ejection pulse for small parts in automated machinery where a shorter profile body is required to fit tight spaces.
Replacing the Airtac SU32~50 Standard Cylinder SU40X10 with the SAU40X10
To replace the discontinued SU40X10, order the SAU40X10 direct equivalent, ensuring you keep the 40mm bore, 10mm stroke, M12x1.25 rod thread, and 1/4" port. Because this SKU has no -S magnet, it cannot support sensing; if you need position detection on the SAU, specify the -S option and upgrade to CMSG/DMSG/EMSG switches. If you need higher force, the neighboring 50mm bore offers 982N push at 0.5MPa; if you need less, the 32mm bore provides 402N. The 10mm stroke is very short, so side-load risks are minimal, but remember a standard cylinder does not hold load without air—the cushion only decelerates. For load holding, add an external rod lock or pilot-operated check valve. The SAUF variant can simplify actuation by integrating a valve directly on the body.
Replacement checklist
- ✓ Same bore / stroke → SAU40X10
- ✓ 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 SU40X10 FAQ
Yes, the AirTAC SU40X10 is discontinued and end-of-life. The direct replacement is the SAU40X10. It shares the identical 40mm bore, 10mm stroke, 628N force, 1/4" port, and SC-series mounting hardware, so it fits the same application directly.
The 40mm bore provides 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, and a theoretical max of 128kgf at 1.0MPa. This specific SU40X10 SKU lacks a magnet and cannot take a sensor. The SAU40X10 replacement supports CMSG/DMSG/EMSG switches if you order the -S magnet version.
