This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X100SCA, 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 SU40X100SCA
The AirTAC SU32~50 Standard Cylinder SU40X100SCA 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 SAU40X100SCA, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X100SCA
The AirTAC SU40X100SCA is a discontinued double-acting profile-type cylinder with a 40mm bore, 100mm stroke, and a 1/4" port. AirTAC replaced it with the SAU40X100SCA, a direct upgrade retaining the exact body dimensions, 628N push force at 0.5MPa, and SC-series CA mounting interface. You simply order the SAU equivalent for identical performance.
This compact extruded-aluminium barrel is shorter than an ISO 15552 cylinder of the same bore. The built-in magnet (-S) worked with legacy CS1-B/DS1-B switches, but the SAU replacement upgrades to CMSG/DMSG/EMSG sensors. The SAU line also introduces the SAUF built-in 4M solenoid valve variant, an option the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X100SCA 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 SAU40X100SCA 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 SU40X100SCA Is Used
Clamping Fixtures
Provides reliable 628N clamping force at 0.5MPa for securing mid-weight machined components during milling or drilling operations.
Package Diverting
Actuates diverting arms on 100mm strokes to route small to medium packaging cartons across sorting lines at speeds up to 800mm/s.
Material Ejection
Pushes completed parts or dunnage out of workstation chutes using a compact profile body that fits tight automation cells.
Replacing the Airtac SU32~50 Standard Cylinder SU40X100SCA with the SAU40X100SCA
To replace this discontinued SU40X100SCA, order the SAU40X100SCA. Confirm the 40mm bore, 100mm stroke, 1/4" port, M12x1.25 rod thread, and CA mounting. Because this SKU includes the -S magnet, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. If sizing alternatives, a 32mm bore provides 402N push at 0.5MPa, while a 50mm bore offers 982N. A plain cylinder drifts without live air; the 21mm cushions only decelerate near stroke end, so use an external rod lock or pilot-operated check valve for load holding. For automated self-switching, consider the SAUF valve-integrated variant.
Replacement checklist
- ✓ Same bore / stroke → SAU40X100SCA
- ✓ 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 SU40X100SCA FAQ
Yes, the AirTAC SU40X100SCA is discontinued. The direct replacement is the SAU40X100SCA. It shares the identical 40mm bore, 100mm stroke, 1/4" port, CA mounting, and output force, fitting the exact same application.
It delivers 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, and a theoretical max of 128kgf at 1.0MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches are obsolete; the SAU replacement requires current CMSG/DMSG/EMSG sensors.
