This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X35SFA, 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 SU50X35SFA
The AirTAC Airtac SU32~50 Standard Cylinder SU50X35SFA 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 SAU50X35SFA, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X35SFA
The AirTAC SU50X35SFA is a discontinued double-acting profile-type cylinder with a 50mm bore, 35mm stroke, and an FA mounting interface. It delivers 982 N of push force at 0.5 MPa through a 1/4" port. AirTAC replaced this EOL unit with the SAU50X35SFA, a direct replacement retaining the exact bore, stroke, output force, and SC-series mounting accessories.
Because of its extruded aluminum barrel, this profile body is shorter and more compact than an ISO 15552 cylinder of the same size. The -S magnet on this legacy SKU worked with CS1-B/DS1-B switches, but the SAU replacement upgrades to CMSG/DMSG/EMSG sensors. Note that the SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X35SFA 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 SAU50X35SFA 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 SU50X35SFA Is Used
Short-Stroke Clamping
Ideal for securing medium workpieces in machining fixtures, utilizing the 982 N push force over a compact 35mm travel.
Package Diverting
Provides reliable actuation for sorting arms on packaging lines, where the FA mount ensures rigid foot mounting.
Replacing the Airtac SU32~50 Standard Cylinder SU50X35SFA with the SAU50X35SFA
To replace this SU50X35SFA, order the SAU50X35SFA, confirming the 50mm bore, 35mm stroke, 1/4" port (PT/G/NPT), and the FA foot-mount interface. If your machine relied on the -S magnet for positioning, you must upgrade your sensors: the legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG switches on the SAU body. If you need integrated flow control, explore the SAUF valve-integrated variant. For sizing alternatives, a 40mm bore yields 628 N push at 0.5 MPa, while a 63mm bore provides 1559 N. Remember that a plain double-acting cylinder drifts on air loss; the adjustable 21mm cushions only decelerate the piston near the end of travel. To hold a load securely during an air failure, install an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAU50X35SFA
- ✓ 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 SU50X35SFA FAQ
Yes, the SU50X35SFA is discontinued. The direct replacement is the AirTAC SAU50X35SFA. It shares the same 50mm bore, 35mm stroke, 1/4" port, and SC-series FA mounting, so it fits the same application without mechanical changes.
At 0.5 MPa it provides 982 N push and 825 N pull force, reaching 1374 N push at 0.7 MPa, and a theoretical max of 200 kgf at 1.0 MPa. Because this SKU includes a magnet (-S), note that the legacy CS1-B/DS1-B switches are obsolete; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
