This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X65S, 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 SU50X65S
The AirTAC Airtac SU32~50 Standard Cylinder SU50X65S is a double-acting profile-type standard cylinder with a Ø50mm bore and 65mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X65S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X65S
The AirTAC SU50X65S is a discontinued double-acting profile-type cylinder featuring a 50mm bore, 65mm stroke, and a built-in magnet. The extruded aluminum body makes it shorter and more compact than an ISO 15552 cylinder of the same bore.
AirTAC replaced this unit with the SAU50X65S, a direct replacement retaining the exact bore, stroke, force, 1/4" port, and SC-series mounting. The upgrade introduces current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here, and the SAUF variant offers a built-in valve the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X65S 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 SAU50X65S 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. |
| ×65 | 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 SU50X65S Is Used
Clamping Mechanisms
Ideal for mid-range clamping tasks requiring 982 N of push force at 0.5 MPa to secure parts during machining.
Package Diverting
Provides reliable 65mm stroke actuation to push or divert medium-weight packages along a production line.
Replacing the Airtac SU32~50 Standard Cylinder SU50X65S with the SAU50X65S
To replace this SU50X65S, order the SAU50X65S and confirm your 1/4" port thread (PT, G, or NPT) plus SC-series mounting. Because this SKU has the -S magnet, note that your old CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. Sizing both ways: dropping to a 40mm bore gives 628 N push, while stepping up to 63mm yields 1559 N. A plain cylinder drifts without live air—the cushion only decelerates—so use an external rod lock for suspended loads.
Replacement checklist
- ✓ Same bore / stroke → SAU50X65S
- ✓ 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 SU50X65S FAQ
Yes, the SU50X65S is discontinued. The direct replacement is the AirTAC SAU50X65S. It shares the same 50mm bore, 65mm stroke, output force, 1/4" port, and SC-series mounting, so it fits the same application without mechanical modifications.
The bore is 50mm with a 1/4" port. Force ratings are 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 an -S model with a magnet, it used legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
