This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X35CA, 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 SU50X35CA
The AirTAC Airtac SU32~50 Standard Cylinder SU50X35CA is a double-acting profile-type standard cylinder with a Ø50mm bore and 35mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X35CA, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X35CA
The AirTAC SU50X35CA is a discontinued double-acting profile-type cylinder with a 50mm bore and 35mm stroke. It delivers 982N push force at 0.5MPa via a 1/4" port. AirTAC replaced this unit with the SAU50X35CA, a direct replacement retaining the exact bore, stroke, output force, and SC-series CA mounting.
The SAU upgrade introduces current CMSG/DMSG/EMSG sensors and a new SAUF built-in 4M valve option the SU lacked. This non-magnetic SKU cannot accept a sensor. Note that the cushion only decelerates; it does not hold load without live air.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X35CA 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 SAU50X35CA 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 SU50X35CA Is Used
Short-Stroke Clamping
Ideal for securing mid-weight workpieces in machining fixtures, using the 35mm stroke to clamp parts firmly with 589N of safe working force.
Package Diverting
Provides rapid actuation for sorting or diverting items on a production line, where the compact profile saves space and the 982N thrust easily pushes goods.
Pallet Stopper Gate
Functions as a reliable stop mechanism for pallets up to 50kg, deploying the short rod to halt movement before retracting to release the load.
Replacing the Airtac SU32~50 Standard Cylinder SU50X35CA with the SAU50X35CA
To replace the SU50X35CA, order the SAU50X35CA and confirm the 1/4" port, M16x1.5 rod thread, and CA mounting accessory. This non-magnetic version cannot take a switch; if sensing is needed, specify an SAU -S model and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. If you need higher force, the 63mm bore offers 1559N push at 0.5MPa; if lower force fits, the 40mm bore provides 628N. For load holding on air loss, add an external rod lock or pilot-operated check valve, as the cushion only decelerates. The SAUF valve-integrated variant is an option if you want to simplify actuation control.
Replacement checklist
- ✓ Same bore / stroke → SAU50X35CA
- ✓ 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 SU50X35CA FAQ
Yes, the SU50X35CA is discontinued. The direct replacement is the AirTAC SAU50X35CA. It shares the exact same 50mm bore, 35mm stroke, 982N force, 1/4" port, and SC-series CA mounting, so it fits the same application without modification.
This 50mm bore cylinder delivers 982N push and 825N pull at 0.5MPa, 1374N push at 0.7MPa, and a theoretical max of 200kgf at 1.0MPa. Because this specific SKU lacks a magnet, it cannot accept a sensor; the SAU -S replacement uses CMSG/DMSG/EMSG switches.
