This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X290S, 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 SU32X290S
The AirTAC SU32~50 Standard Cylinder SU32X290S is a double-acting profile-type standard cylinder with a Ø32mm bore and 290mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X290S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X290S
The AirTAC SU32X290S is a discontinued double-acting profile-type cylinder with a 32 mm bore and 290 mm stroke, delivering 402 N push force at 0.5 MPa. AirTAC replaced this legacy unit with the SAU32X290S, a direct alternative retaining the exact same extruded body dimensions, output force, 1/8" porting, and SC-series mounting hardware.
Because this SU variant includes a piston magnet (-S), it originally operated with legacy CS1-B/DS1-B reed switches; upgrading to the SAU requires switching to the current CMSG/DMSG/EMSG sensor family. The SAU line also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X290S 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 SAU32X290S 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 SU32X290S Is Used
Small Part Ejection
Uses the 402 N push force at 0.5 MPa to reliably knock lightweight molded parts out of a fixture on an injection molding machine.
Package Diverting
Extends 290 mm to push small cartons off a main conveyor belt line, safely handling loads under the 20 kg vertical lift threshold.
Sorter Gating
Actuates a routing gate in a distribution hub, benefiting from the compact profile body to fit within tight conveyor framework.
Replacing the Airtac SU32~50 Standard Cylinder SU32X290S with the SAU32X290S
To replace the discontinued SU32X290S, order the SAU32X290S and verify your 1/8" port threads (PT, G, or NPT) and SC-series mounting brackets (LB, FA, FB, CA, CB, TC). If relying on the -S magnet for positioning, note that your legacy CS1-B/DS1-B switches must be replaced by CMSG/DMSG/EMSG sensors. For higher force needs, a 40 mm bore provides 628 N push at 0.5 MPa, while a 32 mm bore is sufficient if loads stay near 241 N. At 290 mm stroke, ensure guide rails carry side loads to prevent rod bending. The cylinder does not hold load without live air—use an external rod lock for safety. The SAUF valve-integrated model is available if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU32X290S
- ✓ 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 SU32X290S FAQ
Yes, the SU32X290S is discontinued. The direct replacement is the AirTAC SAU32X290S. It matches the 32 mm bore, 290 mm stroke, 1/8" port, output force, and SC-series mounting accessories, so it fits the same application without mechanical modifications.
The 32 mm bore provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical max of 82 kgf at 1.0 MPa. Because this is the -S magnet version, it used legacy CS1-B/DS1-B switches; the SAU replacement requires upgrading to CMSG/DMSG/EMSG sensors.
