This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X200SN, 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 SU40X200SN
The AirTAC SU32~50 Standard Cylinder SU40X200SN is a double-acting profile-type standard cylinder with a Ø40mm bore and 200mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X200SN, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X200SN
The AirTAC SU40X200SN is a discontinued double-acting profile-type cylinder with a 40mm bore and 200mm stroke. It delivers 628N push and 528N pull at 0.5MPa, utilizing a 1/4 inch port and a 16mm piston rod. AirTAC replaced this EOL unit with the SAU40X200SN, a direct upgrade retaining the exact bore, stroke, output force, port size, and SC-series mounting compatibility.
The SAU replacement modernizes the sensor groove, requiring CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B reed sensors used here, while introducing the SAUF built-in 4M valve option the SU line lacked. The NBR seal supports -20 to +70C, and the extruded aluminum body is more compact than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X200SN 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 SAU40X200SN 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 SU40X200SN Is Used
Package Diverting
Actuates diverting arms on 1/4" port pneumatic lines to push 32kg cartons off a main belt at 30-800 mm/s speeds.
Roller Gate Control
Provides 377N safe working force to open and close gravity roller lane gates in distribution hubs using SC-series mounts.
Small Press Ejection
Ejects molded components from a 40mm bore compact profile body, fitting into tight machine frames where ISO cylinders fail.
Replacing the Airtac SU32~50 Standard Cylinder SU40X200SN with the SAU40X200SN
To replace this SU40X200SN, order the SAU40X200SN direct equivalent, confirming the 40mm bore, 200mm stroke, 1/4" port, M12x1.25 rod thread, and SC-series mounting hardware are retained. Because this SKU has a magnet, note that your existing CS1-B/DS1-B switches must be upgraded to CMSG/DMSG/EMSG sensors on the SAU body. If you need higher force, the neighboring 50mm bore provides 982N push at 0.5MPa; if less is required, the 32mm bore offers 402N. Remember that a standard cylinder does not hold load without live air—the 21mm cushions only decelerate—so add an external rod lock or pilot-operated check valve for vertical holding. At 200mm stroke, side-load is minimal, but ensure the load is guided to prevent rod bending.
Replacement checklist
- ✓ Same bore / stroke → SAU40X200SN
- ✓ 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 SU40X200SN FAQ
Yes, the SU40X200SN is discontinued and end-of-life. The direct replacement is the AirTAC SAU40X200SN. It shares the identical 40mm bore, 200mm stroke, 628N push force at 0.5MPa, 1/4" port, and SC-series mounting accessories, so it drops into the same application. You just order the SAU equivalent.
This 40mm bore cylinder provides 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, and a theoretical max of 128kgf at 1.0MPa. Because this model includes a magnet (-S), it used the legacy CS1-B/DS1-B switches. The SAU40X200SN replacement requires upgrading to the current CMSG/DMSG/EMSG sensor family.
