This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X630S, 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 SU32X630S is a double-acting profile-type standard cylinder with a Ø32mm bore and 630mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X630S, which matches its bore, stroke, force and mounting.
The AirTAC SU32X630S is a discontinued double-acting profile-type cylinder with a 32mm bore and 630mm stroke. It delivers 402N push force at 0.5MPa via a 1/8" port. AirTAC replaced it with the SAU32X630S, a direct upgrade retaining the exact bore, stroke, force, port size and SC-series mounting.
The SAU upgrade uses current CMSG/DMSG/EMSG sensors instead of this unit's legacy CS1-B/DS1-B switches, and introduces the SAUF valve-integrated option. The 630mm length requires external guides to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X630S 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 SAU32X630S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 32 | Bore size in mm. |
| ×630 | 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.
Moves lightweight tote bins between packaging stations, requiring external guides to support the long 630mm rod extension.
Indexes small clamping fixtures along a 630mm path where the compact 32mm profile body saves valuable machine space.
To replace this SU32X630S, order the SAU32X630S, confirming the 32mm bore, 630mm 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 CMSG/DMSG/EMSG sensors on the SAU. If you need higher force, the neighbouring 40mm bore yields 628N push at 0.5MPa. For the 630mm stroke, use external guides to prevent rod-bending side loads. A plain cylinder drifts on air loss—the cushion only decelerates—so add a rod lock or pilot-operated check valve for load holding. The SAUF variant offers a built-in valve if needed.
Replacement checklist
Yes, the SU32X630S is discontinued. The direct replacement is the AirTAC SAU32X630S, which matches the 32mm bore, 630mm stroke, 402N force, 1/8" port and SC-series mounting.
It delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and an 82kgf max at 1.0MPa. The -S magnet works with legacy CS1-B/DS1-B switches, but the SAU replacement requires CMSG/DMSG/EMSG sensors.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X630S replacement — usually within 7-8 hours.
