This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X325, 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 SU63-100 Standard Cylinder SU80X325 is a double-acting profile-type standard cylinder with a Ø80mm bore and 325mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X325, which matches its bore, stroke, force and mounting.
The AirTAC SU80X325 is a discontinued double-acting profile-type cylinder with an 80mm bore and 325mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa, operating at 30-800mm/s through a 3/8 port. AirTAC replaced this unit with the SAU80X325, a direct alternative retaining the exact bore, stroke, force, and SC-series mounting.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors (replacing the legacy CS1-B/DS1-B switches) and a SAUF built-in-valve variant absent from the SU line. Because this specific SKU lacks a magnet, it cannot accept any sensor.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X325 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAU80X325 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 80 | Bore size in mm. |
| ×325 | 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 heavy pallet routing on packaging lines, utilizing the 2513N push force at 0.5MPa to reliably shift loads onto adjacent conveyors.
Ejects formed metal or plastic parts from press beds, absorbing end-of-stroke impact via the 28mm adjustable air cushions.
To replace the SU80X325, order the SAU80X325, confirming the 80mm bore, 325mm stroke, 3/8 port, M20x1.5 rod thread, and SC-series mounting. If sizing neighbors, a 63mm bore yields 1559N push while a 100mm bore yields 3927N at 0.5MPa. This non-magnet SKU cannot support sensing; if switches are needed, specify an -S SAU model and migrate to CMSG/DMSG/EMSG sensors. For the 325mm stroke, use an external guide to prevent rod bending under side loads. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so add a rod lock or pilot check valve to hold loads. The SAUF valve-integrated option can also simplify actuation.
Replacement checklist
Yes, the SU80X325 is discontinued. The direct replacement is the AirTAC SAU80X325, which matches the 80mm bore, 325mm stroke, 2513N force, 3/8 port, and SC-series mounting.
It provides 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a 513kgf max at 1.0MPa. This specific SKU has no magnet and cannot take sensors; the SAU replacement uses CMSG/DMSG/EMSG switches on -S models.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU80X325 replacement — usually within 7-8 hours.
