This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X330SH, 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 SU40X330SH
The AirTAC SU32~50 Standard Cylinder SU40X330SH is a double-acting profile-type standard cylinder with a Ø40mm bore and 330mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X330SH, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X330SH
The AirTAC SU40X330SH is a discontinued double-acting profile-type cylinder with a 40mm bore and 330mm stroke. It delivers 628N push and 528N pull at 0.5MPa, utilizing a 1/4" port and a 16mm piston rod. AirTAC replaced this end-of-line unit with the SAU40X330SH, a direct upgrade retaining the exact profile body, force, port size, and SC-series mounting compatibility.
This unit includes a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement transitions to current CMSG/DMSG/EMSG sensors. The H designation indicates Viton FKM seals for 0-150C environments. The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, an option the original SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X330SH 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 SAU40X330SH 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 SU40X330SH Is Used
Hot End Product Diversion
Routes heat-resistant packages along processing lines using the 330mm stroke and Viton FKM seals rated for 0-150C environments.
High-Temperature Forming Ejector
Pushes molded components out of heated machinery, leveraging the 628N push force at 0.5MPa with reliable high-temp operation.
Extended Reach Pallet Stops
Acts as a 330mm extended stopper arm for pallet positioning, requiring external guides to manage the long stroke side-load.
Replacing the Airtac SU32~50 Standard Cylinder SU40X330SH with the SAU40X330SH
To replace this discontinued SU40X330SH, order the SAU40X330SH. Verify your 1/4" port threads (PT, G, or NPT), M12x1.25 rod-end connection, and SC-series mounting hardware. Because this SKU has the -S magnet, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the new cylinder. The 330mm stroke exceeds 300mm, so use an external guide to prevent rod bending and side-load wear. For sizing alternatives, the neighboring 32mm bore yields 402N push at 0.5MPa, while the 50mm bore provides 982N. A plain cylinder drifts without live air—the 21mm cushions only decelerate; integrate an external rod lock or pilot-operated check valve for secure load holding. If you need self-switching, explore the SAUF valve-integrated option.
Replacement checklist
- ✓ Same bore / stroke → SAU40X330SH
- ✓ 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 SU40X330SH FAQ
Yes, the SU40X330SH is discontinued. The direct replacement is the SAU40X330SH. It matches the 40mm bore, 330mm stroke, 628N output force, 1/4" port, and SC-series mounting. You simply order the SAU equivalent.
It delivers 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, and a 128kgf maximum at 1.0MPa. Because this model has the -S magnet, it used legacy CS1-B/DS1-B switches; the SAU replacement requires current CMSG/DMSG/EMSG sensors.
