This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X530S, 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 SU50X530S
The AirTAC SU32~50 Standard Cylinder SU50X530S is a double-acting profile-type standard cylinder with a Ø50mm bore and 530mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X530S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X530S
The AirTAC SU50X530S is a discontinued double-acting profile cylinder with a 50mm bore and 530mm stroke, delivering 982 N of push force at 0.5 MPa. AirTAC replaced this legacy unit with the SAU50X530S. This direct upgrade matches the original 1/4" port, M16x1.5 rod thread, output force, and SC-series mounting accessories, fitting the exact same application space.
The extruded aluminum profile body is more compact than an ISO 15552 cylinder of the same bore. Because this SKU includes a magnet (-S), it used legacy CS1-B/DS1-B switches; the SAU replacement transitions to current CMSG/DMSG/EMSG sensors. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve that the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X530S 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 SAU50X530S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 50 | Bore size in mm. |
| ×530 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SU50X530S Is Used
Carton Diverting
Pushes packages at 30-800 mm/s on packaging lines, using the 982 N push force to redirect heavy goods without stalling.
Pallet Handling
Extends 530mm to index pallets into wrapping stations, requiring external guides to support the long rod extension safely.
Material Pressing
Applies up to 200 kgf at 1.0 MPa to hold components during light assembly pressing, utilizing adjustable 21mm cushions for soft stops.
Replacing the Airtac SU32~50 Standard Cylinder SU50X530S with the SAU50X530S
To replace this SU50X530S, order the SAU50X530S direct equivalent, verifying your 50mm bore, 530mm stroke, 1/4" port (default PT, but check for G or NPT), and M16x1.5 rod thread. Confirm your SC-series mounting (LB/FA/FB/CA/CB) carries over directly. If sizing alternatives, neighboring bores shift force significantly: a 40mm bore provides 628 N push at 0.5 MPa, while a 63mm bore yields 1559 N. Because this is a 530mm stroke, add external guide rails to prevent rod bending under side loads. Note the -S magnet upgrade: your old CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG sensors on the SAU. A plain cylinder does not hold load on air loss—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for suspended loads. If self-switching is needed, explore the SAUF built-in-valve option.
Replacement checklist
- ✓ Same bore / stroke → SAU50X530S
- ✓ 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 SU50X530S FAQ
Yes, the SU50X530S is discontinued. The direct replacement is the AirTAC SAU50X530S. It shares the same 50mm bore, 530mm stroke, 982 N force at 0.5 MPa, 1/4" port, and SC-series mounting, so it drops directly into your existing application.
This 50mm bore cylinder delivers 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a theoretical max of 200 kgf at 1.0 MPa. Because this is the -S magnet version, it originally used CS1-B/DS1-B switches; the SAU replacement requires the newer CMSG/DMSG/EMSG sensor family.
