This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X290, 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 SU50X290
The AirTAC Airtac SU32~50 Standard Cylinder SU50X290 is a double-acting profile-type standard cylinder with a Ø50mm bore and 290mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X290, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X290
The AirTAC SU50X290 is a discontinued double-acting profile-type cylinder with a 50mm bore and 290mm stroke. It delivers 982N push and 825N pull at 0.5MPa via a 1/4" port. The direct replacement is the SAU50X290, matching the body, force, and SC-series mounts.
This SKU lacks a magnet, so it cannot accept a sensor. The SAU upgrade uses current CMSG/DMSG/EMSG switches and adds a SAUF valve-integrated option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X290 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAU50X290 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 SU50X290 Is Used
Package Diverting
Pushes cartons at 90 degrees on a sorting line using the 982N push force at 0.5MPa, with the 290mm stroke clearing side guides.
Pallet Stopper
Acts as a pneumatic stop for incoming pallets, safely absorbing kinetic energy using the 21mm adjustable air cushions at both ends.
Component Ejector
Ejects machined parts from a fixture; the 50kg safe vertical lift capacity handles lightweight metal components reliably.
Replacing the Airtac SU32~50 Standard Cylinder SU50X290 with the SAU50X290
To replace this SU50X290, order the SAU50X290 with the same 50mm bore, 290mm stroke, 1/4" port, M16x1.5 rod thread, and SC-series mounting. Because this SKU has no -S magnet, it cannot take a sensor; if sensing is needed, order the SAU equivalent with -S and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For sizing, the neighbouring 40mm bore offers 628N push @0.5MPa, while the 63mm bore provides 1559N. At 290mm stroke, guide the load to prevent rod bending. The cylinder does not hold load without live air; use an external rod lock or pilot-operated check valve for holding. The SAUF variant offers a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU50X290
- ✓ 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 SU50X290 FAQ
Yes, the SU50X290 is discontinued. The direct replacement is the SAU50X290. It matches the 50mm bore, 290mm stroke, 982N force, 1/4" port, and SC-series mounting. The body dimensions are identical, making it a direct fit.
At 0.5MPa it pushes 982N and pulls 825N; at 0.7MPa it pushes 1374N, with a theoretical max of 200kgf at 1.0MPa. The cylinder does not hold a load without live air; the 21mm cushions only decelerate near stroke end. For load holding, use an external rod lock or pilot-operated check valve.
