This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X100CA, 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 SU50X100CA
The AirTAC Airtac SU32~50 Standard Cylinder SU50X100CA is a double-acting profile-type standard cylinder with a Ø50mm bore and 100mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X100CA, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X100CA
The AirTAC SU50X100CA is a discontinued double-acting profile-type cylinder with a 50mm bore and 100mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 cylinder of the same bore while delivering 982 N push force at 0.5 MPa. The direct replacement is the SAU50X100CA, matching the bore, stroke, 1/4" port, and CA mounting interface.
Because this SKU lacks a magnet, it cannot accept a sensor. If sensing is needed, the SAU upgrade supports current CMSG/DMSG/EMSG switches, whereas the older SU line used CS1-B/DS1-B. The SAU family also adds a SAUF variant with a built-in 4M solenoid valve.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X100CA 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 SAU50X100CA 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 SU50X100CA Is Used
Clamping Fixtures
Holds workpieces securely in machining jigs using 982 N of thrust at 0.5 MPa, with the 100mm stroke providing ample reach for varied part sizes.
Pallet Stops
Acts as a pneumatic stop gate in low-profile material handling conveyors where the compact extruded body saves space over standard ISO cylinders.
Replacing the Airtac SU32~50 Standard Cylinder SU50X100CA with the SAU50X100CA
To replace the SU50X100CA, order the SAU50X100CA and confirm the 50mm bore, 100mm stroke, 1/4" port (default PT thread), M16x1.5 rod thread, and CA mounting accessory. Since this specific SKU has no magnet (-S), it cannot support magnetic sensing; if you require position detection, the SAU replacement requires the newer CMSG/DMSG/EMSG switch family rather than the legacy CS1-B/DS1-B. For higher force needs, stepping up to a 63mm bore yields 1559 N push at 0.5 MPa; for lighter loads, a 40mm bore provides 628 N. Note that a standard cylinder drifts without live air—the 21mm adjustable cushion only decelerates at stroke end—so use an external rod lock or pilot-operated check valve for secure load holding. The SAUF valve-integrated option is also available if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU50X100CA
- ✓ 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 SU50X100CA FAQ
Yes, the SU50X100CA is discontinued. The direct replacement is the AirTAC SAU50X100CA. It shares the same 50mm bore, 100mm stroke, 1/4" port, output force, and SC-series CA mounting, fitting the same application directly.
This 50mm bore double-acting cylinder delivers 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a theoretical maximum of 200 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches.
