This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X100CA, 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 SU40X100CA
The AirTAC Airtac SU32~50 Standard Cylinder SU40X100CA is a double-acting profile-type standard cylinder with a Ø40mm bore and 100mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X100CA, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X100CA
The AirTAC SU40X100CA is a discontinued double-acting profile-type cylinder with a 40mm bore and 100mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 unit of the same bore and delivers 628 N push / 528 N pull at 0.5 MPa via a 1/4" port. AirTAC replaced this EOL unit with the SAU40X100CA direct replacement, matching the exact CA mounting, M12x1.25 rod thread, and 128 kgf maximum force.
Because this SKU lacks a magnet, it cannot accept a sensor. If you previously used an -S variant, note the SAU upgrade transitions from legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG family. The SAU line also introduces a SAUF built-in 4M solenoid valve option the SU never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X100CA 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 SAU40X100CA 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 SU40X100CA Is Used
Package Diverting
Drives a CA-mounted clever arm to push 20 kg cartons off a sorting line, utilizing the 628 N push force at 0.5 MPa for reliable lateral diversion.
Clamp Actuation
Secures medium aluminum extrusions during machining operations, where the 528 N pull force at 0.5 MPa provides firm holding without deforming the workpiece.
Stopper Gate Control
Raises and lowers pallet stop gates at 100mm stroke, taking advantage of the compact profile body to fit within tight conveyor framework.
Replacing the Airtac SU32~50 Standard Cylinder SU40X100CA with the SAU40X100CA
To replace this SU40X100CA, order the SAU40X100CA, which preserves the 40mm bore, 100mm stroke, 1/4" port, and CA clevis mount interface. Verify your thread standard (PT, G, or NPT) during ordering. Since this specific SKU has no -S magnet, it cannot support position sensing; if your application requires switches, select an -S SAU model and upgrade to CMSG/DMSG/EMSG sensors. For force context, the 40mm bore yields 628 N push at 0.5 MPa, whereas stepping down to a 32mm bore drops thrust to 402 N, and stepping up to a 50mm bore increases it to 982 N. Remember that a standard cylinder does not hold load on air loss—the 21mm adjustable cushions only decelerate near stroke end—so add an external rod lock or pilot-operated check valve for suspended loads.
Replacement checklist
- ✓ Same bore / stroke → SAU40X100CA
- ✓ 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 SU40X100CA FAQ
Yes, the AirTAC SU40X100CA is discontinued. The direct replacement is the SAU40X100CA. It matches the 40mm bore, 100mm stroke, 1/4" port, CA mounting, and 128 kgf maximum force. You simply order the SAU equivalent for a direct physical swap.
The 40mm bore 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. Because this specific SKU lacks a -S magnet, it cannot accept a sensor. If you need sensing, the SAU replacement requires CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
