This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X50CA, 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 SU50X50CA
The AirTAC SU32~50 Standard Cylinder SU50X50CA is a double-acting profile-type standard cylinder with a Ø50mm bore and 50mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X50CA, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X50CA
The AirTAC SU50X50CA is a discontinued double-acting profile-type cylinder with a 50mm bore and 50mm stroke. Delivering 982N push force at 0.5MPa through a 1/4" port, it is replaced by the SAU50X50CA. This direct successor shares the exact bore, stroke, output, and SC-series CA mounting.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU family also introduces the SAUF variant with a built-in 4M valve.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X50CA 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 SAU50X50CA 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 SU50X50CA Is Used
Clamp Actuation
Provides 982N of push force at 0.5MPa to secure workpieces in CNC machining fixtures.
Part Diverter
Short 50mm stroke pushes lightweight packages off a production line using the CA clevis mount.
Replacing the Airtac SU32~50 Standard Cylinder SU50X50CA with the SAU50X50CA
To replace the SU50X50CA, order the SAU50X50CA. Verify your 1/4" port threads (PT/G/NPT) and CA clevis mount. Since this is a non-magnetic SKU, it cannot hold a switch; if you need position sensing, order an SAU -S model and use CMSG/DMSG/EMSG switches. For loads needing 1767N push at 0.9MPa, step up to a 63mm bore. A plain cylinder drifts without air; use an external rod lock for holding. The 50mm stroke avoids side-load rod-bending risks seen on longer strokes.
Replacement checklist
- ✓ Same bore / stroke → SAU50X50CA
- ✓ 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 SU50X50CA FAQ
Yes, the SU50X50CA is discontinued. The direct replacement is the SAU50X50CA, which matches the 50mm bore, 50mm stroke, 1/4" port, and CA mounting.
It delivers 982N push and 825N pull at 0.5MPa, 1374N push at 0.7MPa, and a 200kgf max at 1.0MPa. Because this specific SKU lacks a magnet, it cannot accept legacy CS1-B/DS1-B switches.
