This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X380SH, 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 SU40X380SH
The AirTAC SU32~50 Standard Cylinder SU40X380SH is a double-acting profile-type standard cylinder with a Ø40mm bore and 380mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X380SH, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X380SH
The AirTAC SU40X380SH is a discontinued double-acting profile-type cylinder with a 40mm bore and 380mm stroke. It delivers 628 N push force at 0.5 MPa and features a high-temperature Viton H seal (0-150 C) alongside a 1/4" port. AirTAC replaced this legacy unit with the SAU40X380SH, a direct alternative retaining the exact bore, stroke, force, port, and SC-series mounting.
The SAU upgrade introduces current CMSG/DMSG/EMSG sensors, replacing the older CS1-B/DS1-B switches used on this SU -S model, and offers a new SAUF valve-integrated variant. Note that the 380mm stroke requires external guides to prevent rod bending, and plain cylinders drift without live air.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X380SH 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 SAU40X380SH 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 SU40X380SH Is Used
Hot End Ejection
Uses the Viton H seal to withstand 150 C ambient heat while pushing parts out of molding zones with 628 N at 0.5 MPa.
Extended Transfer
The 380mm stroke reaches across wider belts to index products, requiring external guides to prevent rod bending over the long travel.
Replacing the Airtac SU32~50 Standard Cylinder SU40X380SH with the SAU40X380SH
To replace this SU with the SAU40X380SH, verify the 40mm bore, 380mm stroke, 1/4" port, M12x1.25 rod thread, and SC-series mounting. Because this SKU has a -S magnet, you must switch from legacy CS1-B/DS1-B switches to the SAU's CMSG/DMSG/EMSG sensors. The -H Viton seal allows 0-150 C operation. For sizing alternatives, a 32mm bore yields 402 N push at 0.5 MPa, while a 50mm bore yields 982 N. At 380mm, add external guides to prevent rod bending side-loads. The cushion only decelerates; for load holding on air loss, install an external rod lock or pilot-operated check valve. The SAUF variant adds a built-in 4M valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU40X380SH
- ✓ 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 SU40X380SH FAQ
Yes, the SU40X380SH is discontinued. The direct replacement is the AirTAC SAU40X380SH. It shares the same 40mm bore, 380mm stroke, 1/4" port, output force, and SC-series mounting, but the SAU uses current CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B switches.
This 40mm bore cylinder has a 1/4" air port. It provides 628 N push and 528 N pull at 0.5 MPa, 879 N push at 0.7 MPa, 1130 N at 0.9 MPa, and a theoretical maximum of 128 kgf at 1.0 MPa.
