This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X220S, 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 SU50X220S
The AirTAC SU32~50 Standard Cylinder SU50X220S is a double-acting profile-type standard cylinder with a Ø50mm bore and 220mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X220S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X220S
The AirTAC SU50X220S is a discontinued double-acting profile-type cylinder with a 50 mm bore and 220 mm stroke. Built with an extruded aluminum barrel, it is shorter and more compact than an ISO 15552 cylinder of the same bore.
AirTAC replaced this end-of-life unit with the SAU50X220S, a direct replacement sharing the exact same body dimensions, M16x1.5 rod thread, 21 mm cushions, and SC-series mounting. The SAU upgrade transitions the -S magnet to modern CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches, and introduces the SAUF valve-integrated variant the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X220S 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 SAU50X220S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU32~50 Standard Cylinder SU50X220S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 50 | Bore size in mm. |
| ×220 | 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 SU50X220S Is Used
Package Diverting
Pushes light to medium cartons off a sorting line using 982 N of thrust, safely handling working loads up to 589 N without bouncing.
Clamp Actuation
Secures workpieces in a machining fixture with 825 N pull force at 0.5 MPa, providing stable holding during light milling operations.
Replacing the Airtac SU32~50 Standard Cylinder SU50X220S with the SAU50X220S
To replace this SU50X220S, order the SAU50X220S and verify your 1/4" port thread (PT, G, or NPT) along with your SC-series mounting brackets (LB, FA, FB, CA, CB, TC). Because this SKU includes the -S magnet, note that your old CS1-B/DS1-B reed switches must be upgraded to CMSG/DMSG/EMSG electronic sensors. At 220 mm stroke, side-load risks are low, but always guide the load to prevent rod bending. For sizing alternatives, dropping to a 40 mm bore reduces push force to 628 N at 0.5 MPa, while stepping up to a 63 mm bore increases it to 1559 N. Remember that a standard cylinder drifts without live air; the cushions only decelerate the piston, so fit an external rod lock or pilot-operated check valve if you need to hold a load vertically.
Replacement checklist
- ✓ Same bore / stroke → SAU50X220S
- ✓ 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 SU50X220S FAQ
Yes, the SU50X220S is discontinued. The direct replacement is the AirTAC SAU50X220S. It matches the 50 mm bore, 220 mm stroke, 1/4" port, output force, and SC-series mounting accessories, so it fits the same application directly.
The SAU50X220S matches the SU force ratings: 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 your old SU used a -S magnet with CS1-B/DS1-B switches, you must upgrade to CMSG/DMSG/EMSG sensors on the SAU replacement.
