This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X175S, 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 SU40X175S
The AirTAC SU32~50 Standard Cylinder SU40X175S is a double-acting profile-type standard cylinder with a Ø40mm bore and 175mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X175S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X175S
The AirTAC SU40X175S is a discontinued double-acting profile cylinder with a 40mm bore and 175mm stroke. It delivers 628N push and 528N pull at 0.5MPa through a 1/4" port. The direct replacement is the SAU40X175S, matching the exact body, stroke, force, and SC-series mounting.
This compact extruded-aluminum body is shorter than an ISO 15552 equivalent. The -S magnet used legacy CS1-B/DS1-B switches, whereas the SAU successor takes CMSG/DMSG/EMSG sensors and offers a SAUF valve-integrated variant the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X175S 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 SAU40X175S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU32~50 Standard Cylinder SU40X175S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 40 | Bore size in mm. |
| ×175 | Stroke length in mm. |
| -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 SU40X175S Is Used
Component Clamping
Secures medium workpieces during machining, utilizing the 628N push force at 0.5MPa for firm, stable holding.
Package Diverting
Actuates sorting gates on 40mm profile cylinders, providing reliable 175mm travel to redirect items on a line.
Replacing the Airtac SU32~50 Standard Cylinder SU40X175S with the SAU40X175S
To replace this SU40X175S, order the SAU40X175S keeping the 40mm bore, 175mm stroke, M12x1.25 rod thread, and 1/4" port. Because the -S magnet is present, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. You can reuse your SC-series mounting brackets. If you need higher force, the 50mm bore yields 982N push at 0.5MPa; if less is needed, the 32mm bore gives 402N. A plain cylinder drifts on air loss, so use an external rod lock for held loads. At 175mm, side loads are minor, but ensure front-end alignment to avoid rod bending.
Replacement checklist
- ✓ Same bore / stroke → SAU40X175S
- ✓ 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 SU40X175S FAQ
Yes, the SU40X175S is discontinued. The direct replacement is the SAU40X175S. It matches the 40mm bore, 175mm stroke, 1/4" port, force, and SC-series mounting, so it fits the same application without mechanical changes.
It provides 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, and a 128kgf max at 1.0MPa. The -S suffix means it has a magnet for legacy CS1-B/DS1-B switches; the SAU replacement requires upgrading to CMSG/DMSG/EMSG sensors.
