This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X70S, 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 SU32~50 Standard Cylinder SU32X70S is a double-acting profile-type standard cylinder with a Ø32mm bore and 70mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X70S, which matches its bore, stroke, force and mounting.
The AirTAC SU32X70S is a discontinued double-acting profile-type cylinder with a 32mm bore and 70mm stroke. It delivers 402N push and 345N pull at 0.5MPa via a 1/8 port. AirTAC replaced this legacy unit with the SAU32X70S, a direct replacement retaining the exact bore, stroke, force, port size, and SC-series mounting.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace the legacy CS1-B/DS1-B switches used on this -S model, and offers a new SAUF built-in-valve variant the SU line lacked. The extruded aluminum profile is more compact than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X70S 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 SAU32X70S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 32 | Bore size in mm. |
| ×70 | 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.
Ideal for pushing lightweight molded parts out of a fixture using a safe 241N working load.
Provides reliable 70mm stroke actuation to sort small cartons on a packaging line at up to 800mm/s.
To replace this SU32X70S, order the SAU32X70S direct equivalent, confirming the 32mm bore, 70mm stroke, 1/8 port, M10x1.25 rod thread, and SC-series mounting. Because this SKU includes a magnet (-S), note that your legacy CS1-B/DS1-B switches must change to the current CMSG/DMSG/EMSG family on the SAU. If you need higher force, the neighboring 40mm bore provides 628N push at 0.5MPa; if less force is acceptable, check smaller options. For any load holding, remember a plain cylinder drifts without live air—the cushions only decelerate—so add an external rod lock or pilot-operated check valve. The SAUF variant integrates a 4M solenoid valve if you need self-switching.
Replacement checklist
Yes, the SU32X70S is discontinued. The direct replacement is the AirTAC SAU32X70S. It shares the same 32mm bore, 70mm stroke, 1/8 port, output force, and SC-series mounting, so it fits the same application directly.
The 32mm bore delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG sensors on the new SAU equivalent.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X70S replacement — usually within 7-8 hours.
