This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X475S, 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 SU40X475S
The AirTAC SU32~50 Standard Cylinder SU40X475S is a double-acting profile-type standard cylinder with a Ø40mm bore and 475mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X475S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X475S
The AirTAC SU40X475S is a discontinued double-acting profile-type cylinder with a 40mm bore and 475mm stroke. It delivers 628N push and 528N pull at 0.5MPa, utilizing a 1/4" port and a 16mm piston rod. The direct replacement is the SAU40X475S, preserving the original bore, stroke, output force, port size, and SC-series mounting compatibility.
The SAU upgrade introduces current CMSG/DMSG/EMSG sensors to replace this unit's legacy CS1-B/DS1-B switches, and offers a new SAUF variant with a built-in 4M solenoid valve that the SU line lacked. The extruded aluminum profile is more compact than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X475S 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 SAU40X475S 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 SU40X475S Is Used
Carton Diverting
Pushes packages laterally across sorting lines using the 628N push force, while the 475mm stroke handles wide conveyor transitions.
Pallet Stopper Gate
Acts as an adjustable stop for pallets entering a wrapping station, with the long 475mm travel clearing the conveyor path completely.
Vertical Lift Assist
Raises lightweight product trays weighing up to 32kg, relying on the 40mm bore's 528N pull force to lower them smoothly.
Replacing the Airtac SU32~50 Standard Cylinder SU40X475S with the SAU40X475S
To replace this discontinued SU40X475S, order the SAU40X475S. Verify your 1/4" port threads (PT, G, or NPT), M12x1.25 rod-end connection, and SC-series mounting brackets (LB/FA/FB/CA/CB), as these remain identical. Because this is a 475mm stroke, add external guide rails to prevent rod bending and side-load damage. If sizing down, a 32mm bore provides 402N push at 0.5MPa; if sizing up, a 50mm bore yields 982N. The -S magnet on this legacy model requires CS1-B/DS1-B switches, but the SAU replacement mandates CMSG/DMSG/EMSG sensors. Note that neither cylinder holds a load on air loss; use an external rod lock or pilot-operated check valve for secure holding. The 21mm adjustable cushions only decelerate the piston near stroke ends.
Replacement checklist
- ✓ Same bore / stroke → SAU40X475S
- ✓ 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 SU40X475S FAQ
Yes, the SU40X475S is discontinued. The direct replacement is the SAU40X475S. It matches the 40mm bore, 475mm stroke, 628N push force, 1/4" port, and SC-series mounting accessories, fitting the same application.
The SAU40X475S provides 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, and a theoretical max of 128kgf at 1.0MPa. The legacy CS1-B/DS1-B switches on the SU -S magnet are obsolete; the SAU replacement uses current CMSG/DMSG/EMSG sensors.
