This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X100S, 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 SU40X100S
The AirTAC Airtac SU32~50 Standard Cylinder SU40X100S 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 SAU40X100S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X100S
The AirTAC SU40X100S is a discontinued double-acting profile-type cylinder with a 40mm bore and 100mm stroke. It delivers 628N push force at 0.5MPa through a 1/4" port. The direct replacement is the SAU40X100S, matching the bore, stroke, output, and SC-series mounting.
The SAU upgrade retains the compact extruded aluminum body but modernizes sensing to CMSG/DMSG/EMSG switches (your SU used legacy CS1-B/DS1-B). It also adds an optional SAUF built-in 4M valve.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X100S 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 SAU40X100S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU32~50 Standard Cylinder SU40X100S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 40 | Bore size in mm. |
| ×100 | Stroke length in mm. |
| -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 SU40X100S Is Used
Package Diverting
Pushes medium-weight cartons off a belt line using 628N thrust, fitting neatly within machinery frames.
Pallet Stops
Acts as a pneumatic stop for incoming pallets, absorbing impact with its 21mm adjustable end cushions.
Clamp Actuation
Secures workpieces during machining, providing reliable holding with a 32kg calculated vertical lift capacity.
Replacing the Airtac SU32~50 Standard Cylinder SU40X100S with the SAU40X100S
To replace this SU40X100S, order the SAU40X100S. Confirm your 1/4" port, M12x1.25 rod thread, and SC-series mount. Because your model has the -S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. If you need a self-switching unit, consider the SAUF variant with its built-in valve. For loads needing holding on air loss, add an external rod lock or pilot check valve, as cushions only decelerate. If sizing up or down, a 32mm bore yields 402N push, while a 50mm bore yields 982N at 0.5MPa.
Replacement checklist
- ✓ Same bore / stroke → SAU40X100S
- ✓ 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 SU40X100S FAQ
Yes, the SU40X100S is discontinued. The direct replacement is the AirTAC SAU40X100S. It shares the exact same 40mm bore, 100mm stroke, 1/4" port, output force, and SC-series mounting accessories.
It provides 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, and a 128kgf max at 1.0MPa. Because your model has the -S magnet, note that the SAU replacement upgrades the sensor compatibility from the legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG switches.
