This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X160S, 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.

The AirTAC SU63-100 Standard Cylinder SU80X160S is a double-acting profile-type standard cylinder with a Ø80mm bore and 160mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X160S, which matches its bore, stroke, force and mounting.
The AirTAC SU80X160S is a discontinued double-acting profile-type cylinder with an 80 mm bore and 160 mm stroke. It delivers 2513 N push force at 0.5 MPa and features a 3/8" port. AirTAC replaced this unit with the SAU80X160S, a direct replacement sharing the exact same body, force, and SC-series mounting.
The SAU upgrade switches the legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors, and introduces the SAUF valve-integrated option the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X160S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAU80X160S 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). |
|---|---|
| 80 | Bore size in mm. |
| ×160 | 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.
Secures heavy steel plates during machining using the 2513 N push force at 0.5 MPa, with the 160 mm stroke accommodating thick workpieces.
Pushes loaded pallets off a main conveyor line, leveraging the 128 kg vertical lift equivalent to reliably move substantial weights.
Raises and lowers heavy loading dock gates, where the compact extruded profile saves space compared to standard ISO cylinders.
To replace this SU80X160S, order the SAU80X160S and verify your 3/8" port, M20x1.5 rod thread, and SC-series mounting. Because this SKU includes a magnet (-S), you must swap legacy CS1-B/DS1-B switches for CMSG/DMSG/EMSG sensors. If you need to size both ways, the adjacent 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. For load holding, note that a plain cylinder drifts on air loss—the 28 mm cushions only decelerate; use an external rod lock for suspended loads. The SAUF variant adds a built-in 4M valve if you need self-switching.
Replacement checklist
Yes, the SU80X160S is discontinued. The direct replacement is the AirTAC SAU80X160S. It shares the same 80 mm bore, 160 mm stroke, 3/8" port, output force, and SC-series mounting accessories, so it fits the exact same application.
The 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N at 0.7 MPa, and a theoretical max of 513 kgf at 1.0 MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches must be upgraded to CMSG/DMSG/EMSG sensors on the SAU replacement.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU80X160S replacement — usually within 7-8 hours.
