This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X225, 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 Airtac SU32~50 Standard Cylinder SU32X225 is a double-acting profile-type standard cylinder with a Ø32mm bore and 225mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X225, which matches its bore, stroke, force and mounting.
The AirTAC SU32X225 is a discontinued double-acting profile-type cylinder with a 32 mm bore and 225 mm stroke. It delivers 402 N push and 345 N pull at 0.5 MPa, operating at 30-800 mm/s through a 1/8" port. The direct replacement is the SAU32X225, matching the bore, stroke, output force, port size and SC-series mounting.
This compact extruded-aluminium body is shorter than an ISO 15552 equivalent of the same bore. The SAU upgrade introduces current CMSG/DMSG/EMSG sensors and a SAUF built-in 4M solenoid valve option the SU line lacked. As a no-magnet SKU, this cylinder cannot accept a sensor.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X225 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 SAU32X225 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -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 eject light machined components from a fixture without damaging the surface.
Actuates a short 225 mm diverting arm to sort small cartons on a conveyor line within the 30-800 mm/s speed range.
To replace this discontinued SU32X225, order the SAU32X225. Confirm the 1/8" port, M10x1.25 rod thread and PT/G/NPT thread choice. Because this is a no-S SKU, it cannot take a magnetic switch; if sensing is needed, order an SAU-S and use CMSG/DMSG/EMSG switches (the SU used legacy CS1-B/DS1-B). Sizing both ways: a 40 mm bore gives 628 N push at 0.5 MPa, while dropping to 0.5 MPa on this 32 mm bore yields 402 N. For load holding, note that a plain cylinder drifts on air loss—the 21 mm cushions only decelerate; use an external rod lock or pilot-operated check valve to hold a load. With a 225 mm stroke, ensure guide alignment to prevent rod bending and side-load wear.
Replacement checklist
Yes, the AirTAC SU32X225 is discontinued and end-of-life. The direct replacement is the SAU32X225. It shares the same 32 mm bore, 225 mm stroke, 1/8" port, output force, and SC-series mounting accessories, fitting the exact same application.
The 32 mm bore provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a theoretical max of 82 kgf at 1.0 MPa. Because this specific SKU lacks a magnet (-S), 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 SAU32X225 replacement — usually within 7-8 hours.
