This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X360, 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 SU40X360
The AirTAC Airtac SU32~50 Standard Cylinder SU40X360 is a double-acting profile-type standard cylinder with a Ø40mm bore and 360mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X360, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X360
The AirTAC SU40X360 is a discontinued double-acting profile-type cylinder with a 40 mm bore and 360 mm stroke. It delivers 628 N push force at 0.5 MPa through a 1/4" port. AirTAC replaced this unit with the SAU40X360, a direct alternative retaining the exact bore, stroke, output force, and SC-series mounting footprint.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU upgrade adds a sensor groove for modern CMSG/DMSG/EMSG switches, plus a new SAUF valve-integrated option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X360 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 SAU40X360 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
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 SU40X360 Is Used
Package Diverting
Drives diverting arms on packaging lines using the 628 N push force at 0.5 MPa to push cartons off the main belt.
Pallet Stopping
Acts as a pneumatic stop for pallets entering a workstation, with the 360 mm stroke accommodating varying pallet depths.
Replacing the Airtac SU32~50 Standard Cylinder SU40X360 with the SAU40X360
To replace this discontinued SU40X360, order the SAU40X360 and confirm your 1/4" port, M12x1.25 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). This non-magnetic SKU cannot hold a switch; if you need sensing on the SAU, specify the -S option and use CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For the 360 mm stroke, use an external guide to prevent rod bending and side-load wear. If checking neighbouring bores, a 32 mm bore yields 402 N push at 0.5 MPa, while a 50 mm bore yields 982 N. Note that air cushions only decelerate; for load holding on air loss, install an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAU40X360
- ✓ 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 SU40X360 FAQ
Yes, the SU40X360 is discontinued. The direct replacement is the AirTAC SAU40X360. It shares the same 40 mm bore, 360 mm stroke, 1/4" port, output force, and SC-series mounting accessories, so it fits the same application directly.
The bore 40 mm cylinder provides 628 N push and 528 N pull at 0.5 MPa, 879 N push at 0.7 MPa, 1130 N push at 0.9 MPa, and a theoretical max of 128 kgf at 1.0 MPa. This specific SKU has no magnet and cannot take a sensor; the SAU replacement with a -S option uses CMSG/DMSG/EMSG switches.
