This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X240S, 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 SU32X240S is a double-acting profile-type standard cylinder with a Ø32mm bore and 240mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X240S, which matches its bore, stroke, force and mounting.
The AirTAC SU32X240S is a discontinued double-acting profile-type cylinder with a 32mm bore and 240mm stroke. Built with an extruded aluminum barrel and adjustable air cushions at both ends, it is shorter and more compact than an ISO 15552 cylinder of the same bore.
Because this SU model is end-of-life, you should order the direct replacement: the SAU32X240S. The SAU shares the same 32mm bore, 240mm stroke, 1/8" port, M10x1.25 rod thread, output force, and SC-series mounting accessories. The magnet-equipped SU-S used legacy CS1-B/DS1-B switches, but the SAU upgrade transitions to current CMSG/DMSG/EMSG sensors. Additionally, the SAU line introduces a SAUF variant with a built-in 4M solenoid valve that the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X240S 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 SAU32X240S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| ×240 | 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 machined components out of a fixture, utilizing the 402 N push force at 0.5 MPa to reliably clear parts without damaging surfaces.
Sort or divert small cartons on a conveyor line, where the 240mm stroke provides ample travel to reach across a narrow transport belt.
Acts as a pneumatic stop in tight assembly cells, taking advantage of the extruded profile body that saves space compared to standard ISO cylinders.
To replace the discontinued SU32X240S, order the SAU32X240S, confirming the 32mm bore, 240mm stroke, 1/8" port (PT/G/NPT), and SC-series mounting (LB/FA/FB/CA/CB) are identical. Because this unit has the -S magnet, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. When sizing, check neighbouring bores: a 40mm bore offers 628 N push at 0.5 MPa if you need more force, while the 32mm provides 402 N. For this 240mm stroke, ensure adequate guide support to prevent rod bending and side-load wear. Remember that a standard cylinder does not hold load without live air—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for suspended loads. If you need self-switching, explore the SAUF valve-integrated option.
Replacement checklist
Yes, the AirTAC SU32X240S is discontinued and end-of-life. The direct replacement is the SAU32X240S. It features the same 32mm bore, 240mm stroke, 1/8" port, output force, and SC-series mounting, so it fits the same application directly.
The 32mm bore provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical max of 82 kgf at 1.0 MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches are retired; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X240S replacement — usually within 7-8 hours.
