This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X190, 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 SU40X190
The AirTAC Airtac SU32~50 Standard Cylinder SU40X190 is a double-acting profile-type standard cylinder with a Ø40mm bore and 190mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X190, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X190
The AirTAC SU40X190 is a discontinued double-acting profile-type cylinder with a 40mm bore and 190mm stroke. It delivers 628N push force at 0.5MPa via a 1/4 inch port. AirTAC replaced this legacy unit with the SAU40X190, a direct alternative retaining the exact bore, stroke, output force, and SC-series mounting footprint.
Because this specific SKU lacks a magnet, it cannot accept a sensing switch. The SAU upgrade introduces modern CMSG/DMSG/EMSG sensors for magnetized variants, plus a SAUF valve-integrated option the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X190 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 SAU40X190 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 SU40X190 Is Used
Package Diverting
Pushes cartons off a sorting line using 628N of thrust at 0.5MPa, with the 190mm stroke clearing guide rails.
Pallet Stop Gate
Acts as a pneumatic stop for lightweight pallets, dropping away to let loads pass on demand.
Component Ejection
Kicks finished molded parts out of a press area, fitting neatly into compact machinery profiles.
Replacing the Airtac SU32~50 Standard Cylinder SU40X190 with the SAU40X190
To replace the SU40X190, order the SAU40X190. Verify your 1/4 inch port thread (PT, G, or NPT), M12x1.25 rod end, and SC-series mounting hardware, as all remain identical. Since this non-magnetic SKU cannot take a sensor, if you need position detection you must buy a magnetized SAU40X190-S and upgrade to CMSG/DMSG/EMSG switches (the old CS1-B/DS1-B are obsolete). If you need more force, the 50mm bore yields 982N push at 0.5MPa; if less is acceptable, the 32mm bore gives 402N. Remember, a standard cylinder drifts on air loss—the 21mm cushions only decelerate near stroke end, so add an external rod lock or pilot-operated check valve for secure load holding. For automated cycling, the SAUF variant integrates a 4M solenoid valve directly on the body.
Replacement checklist
- ✓ Same bore / stroke → SAU40X190
- ✓ 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 SU40X190 FAQ
Yes, the AirTAC SU40X190 is discontinued. The direct replacement is the SAU40X190. It shares the identical 40mm bore, 190mm stroke, 1/4 inch port, and SC-series mounting, so it bolts right in without modifications.
At 0.5MPa it pushes 628N and pulls 528N; at 0.7MPa it pushes 879N, with a theoretical max of 128kgf at 1.0MPa. Because this specific SKU has no magnet, it cannot accept a sensor. If detection is needed, order the SAU40X190-S which uses current CMSG/DMSG/EMSG switches.
