This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X250H, 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 SU32X250H is a double-acting profile-type standard cylinder with a Ø32mm bore and 250mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X250H, which matches its bore, stroke, force and mounting.
The AirTAC SU32X250H is a discontinued double-acting profile-type cylinder with a 32 mm bore, 250 mm stroke, and a Viton H high-temperature seal rated for 0 to 150 C. It delivers 402 N push force at 0.5 MPa via a 1/8" port. AirTAC replaced this unit with the SAU32X250H, a direct upgrade sharing the exact same body, force, and SC-series mounting.
Because this SKU lacks a magnet, it cannot accept a sensor; the SAU upgrade also omits sensing unless ordered with -S. The SAU line additionally introduces a built-in-valve SAUF variant and modern CMSG/DMSG/EMSG switches the SU never supported.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X250H 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 SAU32X250H produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

|---|---|
| 32 | Bore size in mm. |
| ×250 | 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.
Handles 250 mm divert strokes on packaging lines where the compact 32 mm profile fits tight transfer gaps without requiring ISO 15552 space.
Secures small machined components during light milling, using the 345 N pull force at 0.5 MPa while maintaining a minimal footprint.
To replace the discontinued SU32X250H, order the SAU32X250H. Confirm the 1/8" port, M10x1.25 rod thread, and SC-series mounting. This non-magnetic SKU cannot take a switch; if you need sensing, specify an SAU32X250HS and migrate to CMSG/DMSG/EMSG sensors. For load holding, note that the 21 mm cushions only decelerate; add an external rod lock or pilot-operated check valve. At 250 mm stroke, guide the load to prevent rod bending. If 402 N at 0.5 MPa is insufficient, step up to the 40 mm bore (628 N). The SAUF valve-integrated body is a new option if you want to simplify plumbing.
Replacement checklist
Yes, the SU32X250H is discontinued. The direct replacement is the AirTAC SAU32X250H. It shares the identical 32 mm bore, 250 mm stroke, 402 N force, 1/8" port, and SC-series mounting, so it fits the same application directly.
At 0.5 MPa it provides 402 N push and 345 N pull; at 0.7 MPa it pushes 563 N, with a theoretical max of 82 kgf at 1.0 MPa. This specific SKU has no magnet (-S), so it cannot accept a sensor; the SAU replacement with -S uses CMSG/DMSG/EMSG switches.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X250H replacement — usually within 7-8 hours.
