This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X80N, 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 Airtac SU32~50 Standard Cylinder SU32X80N is a double-acting profile-type standard cylinder with a Ø32mm bore and 80mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X80N, which matches its bore, stroke, force and mounting.
The AirTAC SU32X80N is a discontinued double-acting profile-type cylinder with a 32 mm bore and 80 mm stroke. Built with an extruded aluminium barrel, it is more compact than an ISO 15552 cylinder of the same bore and delivers 402 N push force at 0.5 MPa. The direct replacement is the SAU32X80N, matching the bore, stroke, output force, 1/8" port and SC-series mounting.
Because this is the -N NBR seal variant, operating temperature spans -20 to +70 C. As a non-magnetic SKU, it cannot accept a sensing switch. The SAU upgrade also introduces the SAUF valve-integrated option the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X80N carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X80N produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

|---|---|
| 32 | Bore size in mm. |
| ×80 | 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.
Provides 402 N of push at 0.5 MPa to reliably knock small machined components out of a fixture on an automated lathe.
Acts as a compact 80 mm stroke diverter arm on a packaging line, redirecting light cartons without taking up much frame space.
To replace this discontinued SU32X80N, order the SAU32X80N ensuring your 1/8" port thread (PT/G/NPT) and M10x1.25 rod-end specifications match. This non-magnetic SKU cannot take a sensor; if you need position detection, switch to an -S SAU model, noting the SAU family uses current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. If sizing alternatives, a 40 mm bore yields 628 N push at 0.5 MPa, while dropping to a 25 mm stroke shortens the footprint. Note that a plain cylinder drifts on air loss—the 21 mm adjustable cushion only decelerates the piston, so use an external rod lock for held loads. The SAUF variant offers a built-in 4M solenoid valve if you need self-switching.
Replacement checklist
Yes, the AirTAC SU32X80N is discontinued. The direct replacement is the SAU32X80N. It shares the exact same 32 mm bore, 80 mm stroke, 1/8" port, force output and SC-series mounting, so it fits your existing application directly.
At 0.5 MPa it pushes 402 N and pulls 345 N; push is 563 N at 0.7 MPa and 724 N at 0.9 MPa, with a theoretical max of 82 kgf at 1.0 MPa. This specific SKU lacks a magnet, so it cannot accept a sensor; the -S SAU replacement uses CMSG/DMSG/EMSG switches.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X80N replacement — usually within 7-8 hours.
