This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X290CA, 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 SU50X290CA
The AirTAC Airtac SU32~50 Standard Cylinder SU50X290CA 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 SAU50X290CA, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X290CA
The AirTAC SU50X290CA is a discontinued double-acting profile-type cylinder with a 50mm bore and 290mm stroke. It delivers 982N push force at 0.5MPa via a 1/4-inch port. AirTAC replaced this legacy unit with the SAU50X290CA, a direct upgrade retaining the exact bore, stroke, output force, and SC-series CA mounting interface.
Because this SKU lacks a magnet, it cannot accept a piston switch; the SAU upgrade also omits sensing unless specified. The SAU generation modernizes the sensor groove for CMSG/DMSG/EMSG switches and adds the SAUF built-in-valve variant. The cushion only decelerates; use a rod lock to hold loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X290CA 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 SAU50X290CA 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 SU50X290CA Is Used
Mid-Tonnage Clamping
Secures workpieces in CNC machining fixtures using the 982N thrust at 0.5MPa, guided to handle the 290mm extension without rod deflection.
Package Diversion
Actuates routing gates on packaging lines where the 50kg vertical lift capacity and compact profile body fit neatly into tight transfer spaces.
Pallet Stopper Arms
Raises and lowers mechanical stops on roller conveyors, relying on the CA mount and adjustable 21mm cushions to absorb end-of-stroke impact.
Replacing the Airtac SU32~50 Standard Cylinder SU50X290CA with the SAU50X290CA
To replace the SU50X290CA, order the SAU50X290CA. Verify your 1/4-inch port thread (PT, G, or NPT) and the CA mounting bracket. This non-magnetic SKU cannot take a sensor; if you need position detection on the SAU, specify the -S option and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For sizing down, a 40mm bore gives 628N push at 0.5MPa; for higher force, a 63mm bore yields 1559N. At 290mm stroke, guide the load to prevent rod bending and side-load wear. A plain cylinder drifts on air loss—the cushion decelerates but does not lock—so add a pilot-operated check valve for vertical loads. The SAUF valve-integrated variant is available if you want to eliminate external plumbing.
Replacement checklist
- ✓ Same bore / stroke → SAU50X290CA
- ✓ 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 SU50X290CA FAQ
Yes, the SU50X290CA is discontinued. The direct replacement is the AirTAC SAU50X290CA. It shares the identical 50mm bore, 290mm stroke, 982N force, 1/4-inch port, and SC-series CA mounting, so it bolts right in. The SAU also adds the option for a built-in 4M solenoid valve (SAUF variant) the SU line never had.
This 50mm bore cylinder pushes 982N and pulls 825N at 0.5MPa, pushes 1374N at 0.7MPa, and reaches a theoretical max of 200kgf at 1.0MPa. It uses a 1/4-inch port and a 20mm rod. Because this specific SKU lacks a magnet, it cannot accept a sensor. If sensing is required on the SAU replacement, order the -S version and use current CMSG/DMSG/EMSG switches.
