This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X370S, 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 SU32X370S is a double-acting profile-type standard cylinder with a Ø32mm bore and 370mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X370S, which matches its bore, stroke, force and mounting.
The AirTAC SU32X370S is a discontinued double-acting profile-type cylinder with a 32mm bore and 370mm stroke. Delivering 402N push and 345N pull at 0.5MPa, it features a 1/8" port and an extruded aluminium body that is more compact than an ISO 15552 unit of the same bore. AirTAC replaced this EOL unit with the SAU32X370S, a direct replacement retaining the exact force, port size, and SC-series mounting.
This -S SKU includes a piston magnet for legacy CS1-B/DS1-B switches; upgrading to the SAU requires switching to current CMSG/DMSG/EMSG sensors. The SAU family also introduces the SAUF built-in 4M solenoid valve variant, an option the original SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X370S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X370S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 32 | Bore size in mm. |
| ×370 | 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.
Actuates routing gates on packaging lines where the 402N push force easily deflects standard cardboard cartons.
Pushes completed lightweight components out of machining fixtures over the 370mm travel distance.
To replace the SU32X370S, order the SAU32X370S, confirming the 32mm bore, 370mm stroke, 1/8" port, M10x1.25 rod thread, and SC-series mounting. Because this is an -S model, you must change your sensors: the old CS1-B/DS1-B switches will not fit the SAU, so select current CMSG/DMSG/EMSG equivalents. For load holding, note that neither the old SU nor the SAU locks without live air—the cushion only decelerates—so add an external rod lock or pilot-operated check valve if needed. With a 370mm stroke, use an external guide to prevent rod bending and side-load wear. If you need more force, stepping up to a 40mm bore yields 628N push at 0.5MPa; dropping to a smaller bore is not recommended for this length. If you want to simplify plumbing, explore the SAUF variant with its integrated valve.
Replacement checklist
Yes, the AirTAC SU32X370S is discontinued. The direct replacement is the SAU32X370S. It shares the identical 32mm bore, 370mm stroke, 402N force, 1/8" port, and SC-series mounting, so it drops right into your existing setup.
At 0.5MPa it provides 402N push and 345N pull; at 0.7MPa it pushes 563N, with a theoretical max of 82kgf at 1.0MPa. Because this is an -S model with a magnet, it originally used CS1-B/DS1-B switches. The SAU replacement requires upgrading to CMSG/DMSG/EMSG sensors.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X370S replacement — usually within 7-8 hours.
