This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X670S, 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 SU32X670S
The AirTAC SU32~50 Standard Cylinder SU32X670S is a double-acting profile-type standard cylinder with a Ø32mm bore and 670mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X670S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X670S
The AirTAC SU32X670S is a discontinued double-acting profile-type cylinder with a 32mm bore and 670mm stroke, delivering 402N push force at 0.5MPa. AirTAC replaced it with the SAU32X670S, a direct alternative retaining the exact 1/8" port, M10x1.25 rod thread, and SC-series mounting. The extruded aluminum body is more compact than a same-bore ISO 15552 unit.
The -S magnet on this legacy unit worked with CS1-B/DS1-B switches; the SAU replacement uses CMSG/DMSG/EMSG sensors. The SAU line also adds a SAUF valve-integrated option. Because the 670mm stroke is long, use external guides to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X670S 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 SAU32X670S 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 SU32X670S Is Used
Long-Reach Ejection
Extends 670mm to eject small molded parts from a machine bed, requiring external guides to prevent rod bending.
Replacing the Airtac SU32~50 Standard Cylinder SU32X670S with the SAU32X670S
To replace this SU32X670S, order the SAU32X670S, matching the 32mm bore, 670mm stroke, 1/8" port, and SC-series mounting. If your -S magnet used legacy CS1-B/DS1-B switches, you must upgrade to CMSG/DMSG/EMSG sensors on the SAU. For higher force, the 40mm bore offers 628N push at 0.5MPa; for tighter spaces, check smaller SC-series options. A plain cylinder drifts on air loss—the 21mm cushions only decelerate—so add an external rod lock for held loads. With a 670mm stroke, prevent side-load rod bending with an external guide. The SAUF variant offers a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU32X670S
- ✓ 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 SU32X670S FAQ
Yes, the SU32X670S is discontinued. The direct replacement is the AirTAC SAU32X670S. It shares the same 32mm bore, 670mm stroke, 402N force, 1/8" port, and SC-series mounting, but uses CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B switches.
The 32mm bore has a 1/8" port. It delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical max of 82kgf at 1.0MPa.
