This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X63S, 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 SU32X63S is a double-acting profile-type standard cylinder with a Ø32mm bore and 63mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X63S, which matches its bore, stroke, force and mounting.
The AirTAC SU32X63S is a discontinued double-acting profile-type cylinder with a 32 mm bore and 63 mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 unit of the same bore and delivers a 402 N push force at 0.5 MPa. AirTAC replaced this unit with the SAU32X63S, a direct replacement retaining the exact bore, stroke, output force, 1/8" port, and SC-series mounting.
Because this is an -S magnet model, it originally used legacy CS1-B/DS1-B switches; the SAU successor transitions to current CMSG/DMSG/EMSG sensors. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve, an option the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X63S 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 SAU32X63S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 32 | Bore size in mm. |
| ×63 | 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.
Uses the 402 N push force at 0.5 MPa to reliably push lightweight molded plastic parts out of an injection mold cavity.
The 63 mm stroke actuates a diverter arm to route small cardboard cartons on a packaging line without taking up much footprint.
Raises and lowers a pneumatic stop gate to regulate pallet flow on a roller conveyor, fitting within tight machine frames.
To replace this discontinued SU32X63S, order the SAU32X63S. Confirm your 1/8" port thread (PT, G, or NPT), M10x1.25 rod-end thread, and SC-series mounting hardware (LB/FA/FB/CA/CB/TC) all carry over directly. If sizing up or down, a 40 mm bore yields 628 N push at 0.5 MPa, while a 32 mm bore provides 402 N. Note that a plain cylinder drifts on air loss; the 21 mm adjustable cushion only decelerates near stroke end, so add an external rod lock or pilot-operated check valve for held loads. Finally, the -S suffix means you must upgrade your legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors.
Replacement checklist
Yes, the SU32X63S is discontinued. The direct replacement is the AirTAC SAU32X63S. It shares the identical 32 mm bore, 63 mm stroke, output force, 1/8" port, and SC-series mounting accessories, so it bolts right in.
At 0.5 MPa it provides 402 N push and 345 N pull; 563 N push at 0.7 MPa; 724 N at 0.9 MPa; and a theoretical max of 82 kgf at 1.0 MPa. Because this is an -S model, it has a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement requires current CMSG/DMSG/EMSG sensors.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X63S replacement — usually within 7-8 hours.
