This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X900S, 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 SU32X900S
The AirTAC SU32~50 Standard Cylinder SU32X900S is a double-acting profile-type standard cylinder with a Ø32mm bore and 900mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X900S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X900S
The AirTAC SU32X900S is a discontinued double-acting profile-type cylinder with a 32mm bore and 900mm stroke. It delivers 402N push force at 0.5MPa via a 1/8" port. AirTAC replaced it with the SAU32X900S direct replacement, matching the bore, stroke, output, and SC-series mounting.
This compact extruded-aluminium body is shorter than an ISO 15552 equivalent. The -S magnet used legacy CS1-B/DS1-B switches, but the SAU uses CMSG/DMSG/EMSG sensors. The SAU also adds a SAUF valve-integrated option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X900S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X900S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×900 | 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 SU32X900S Is Used
Vertical 20kg Lift
Raises lightweight tote bins 900mm, matching the 20kg vertical lift capacity at 0.5MPa.
Long-Reach Transfer
Moves small electronic components across a 900mm gap, guided to prevent side-load bending.
Replacing the Airtac SU32~50 Standard Cylinder SU32X900S with the SAU32X900S
To replace the SU32X900S, order the SAU32X900S. Confirm the 1/8" port, M10x1.25 rod thread, and SC-series mounting. The -S magnet means you must switch from CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. For the 900mm stroke, use external guides to prevent rod bending. If you need more force, the 40mm bore offers 628N push at 0.5MPa. A plain cylinder drifts on air loss; use a pilot-operated check valve for load holding. Consider the SAUF variant for a built-in valve.
Replacement checklist
- ✓ Same bore / stroke → SAU32X900S
- ✓ 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 SU32X900S FAQ
Yes, the SU32X900S is discontinued. The direct replacement is the SAU32X900S, which matches the 32mm bore, 900mm stroke, 1/8" port, and SC-series mounting.
The SAU32X900S delivers 402N push and 345N pull at 0.5MPa, 563N at 0.7MPa, and 82kgf max at 1.0MPa. The SU -S magnet used CS1-B/DS1-B switches, but the SAU replacement requires CMSG/DMSG/EMSG sensors.
