This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X80SH, 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 SU40X80SH
The AirTAC SU32~50 Standard Cylinder SU40X80SH is a double-acting profile-type standard cylinder with a Ø40mm bore and 80mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X80SH, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X80SH
The AirTAC SU40X80SH is a discontinued double-acting profile cylinder with a 40mm bore and 80mm stroke. It delivers 628 N push and 528 N pull at 0.5 MPa. The direct replacement is the SAU40X80SH, matching the 1/4" port, M12x1.25 rod thread, output force, and SC-series mounting. The extruded aluminum body is more compact than an ISO 15552 cylinder of the same bore.
This unit includes a piston magnet (-S) and high-temperature Viton H seals (-H) rated for 0 to 150 C. The legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG sensors on the SAU. Note that an external rod lock is required to hold loads, as cushions only decelerate.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X80SH 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 SAU40X80SH 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 SU40X80SH Is Used
Hot Product Diversion
Uses the 628 N push force at 0.5 MPa to push heated items on a packaging line, with Viton H seals surviving ambient temperatures up to 150 C.
Replacing the Airtac SU32~50 Standard Cylinder SU40X80SH with the SAU40X80SH
To replace this SU40X80SH, order the SAU40X80SH. Verify your 1/4" port, M12x1.25 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). The -S magnet means you must upgrade from CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. The -H Viton seal handles 150 C environments. If you need higher force, the 50mm bore offers 982 N push at 0.5 MPa; if lower, the 32mm gives 402 N. For load holding on air loss, add a pilot-operated check valve or rod lock, as the 21mm cushions only decelerate. The SAUF variant adds a built-in valve if you need self-switching. At 80mm stroke, side-load is minimal, but ensure guide alignment.
Replacement checklist
- ✓ Same bore / stroke → SAU40X80SH
- ✓ 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 SU40X80SH FAQ
Yes, the AirTAC SU40X80SH is discontinued. The direct replacement is the SAU40X80SH. It shares the same 40mm bore, 80mm stroke, 1/4" port, M12x1.25 rod thread, output force, and SC-series mounting accessories. You simply order the SAU equivalent.
The 40mm bore provides 628 N push and 528 N pull at 0.5 MPa, 879 N push at 0.7 MPa, and a 128 kgf theoretical max at 1.0 MPa. Because this model has the -S magnet, your legacy CS1-B/DS1-B switches will not fit the SAU replacement; you must upgrade to CMSG/DMSG/EMSG sensors.
