This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X900SH, 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 SU40X900SH
The AirTAC SU32~50 Standard Cylinder SU40X900SH is a double-acting profile-type standard cylinder with a Ø40mm bore and 900mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X900SH, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X900SH
The AirTAC SU40X900SH is a discontinued double-acting profile-type cylinder with a 40mm bore and 900mm stroke. Delivering 628N push force at 0.5MPa, its direct replacement is the SAU40X900SH, matching the bore, stroke, 1/4" port, and SC-series mounting. The extruded aluminum body is more compact than an ISO 15552 cylinder of the same bore. This -H variant uses Viton FKM seals for 0-150C high-temperature environments.
Upgrading to the SAU brings current CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used on this -S magnet model. The SAU line also introduces the SAUF built-in 4M solenoid valve option, which the SU series lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X900SH 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 SAU40X900SH 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 SU40X900SH Is Used
High-Temp Ejection
Uses the Viton FKM high-temperature seals to push parts out of hot molding zones up to 150C without degrading.
Long-Reach Diversion
900mm stroke spans wider belts to deflect large packages, requiring external guides to prevent rod bending.
Replacing the Airtac SU32~50 Standard Cylinder SU40X900SH with the SAU40X900SH
To replace this SU40X900SH, order the SAU40X900SH direct equivalent, confirming the 40mm bore, 900mm stroke, 1/4" port, M12x1.25 rod thread, and SC-series mounting. 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. Retain the -H Viton seal for 150C high-heat environments. For sizing alternatives, a 32mm bore offers 402N push at 0.5MPa, while a 50mm bore provides 982N. At 900mm, prevent rod bending by adding an external guide to absorb side loads. A plain cylinder drifts on air loss; the 21mm cushions only decelerate, so use an external rod lock for held loads. The SAUF valve-integrated variant can simplify cycling.
Replacement checklist
- ✓ Same bore / stroke → SAU40X900SH
- ✓ 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 SU40X900SH FAQ
Yes, the SU40X900SH is discontinued. The direct replacement is the SAU40X900SH. It matches the 40mm bore, 900mm stroke, 628N force, 1/4" port, and SC-series mounting. The SAU body is identical, but you must switch from legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors.
At 0.5MPa it pushes 628N and pulls 528N. Push force is 879N at 0.7MPa, 1130N at 0.9MPa, with a 128kgf maximum at 1.0MPa. The 1/4" port and 21mm cushions operate at 30-800mm/s.
