This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X90, 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 SU80X90 is a double-acting profile-type standard cylinder with a Ø80mm bore and 90mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X90, which matches its bore, stroke, force and mounting.
The AirTAC SU80X90 is a discontinued double-acting profile-type cylinder with an 80mm bore and 90mm stroke. Delivering 2513N push force at 0.5MPa, its extruded aluminum barrel is more compact than an ISO 15552 unit of the same bore. AirTAC replaced this unit with the SAU80X90, a direct replacement retaining the exact 3/8" port, M20x1.5 rod thread, and SC-series mounting.
Because this SKU lacks a magnet (-S), it cannot accept a sensor; the SAU upgrade uses CMSG/DMSG/EMSG switches, while the SAUF variant adds a built-in valve the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X90 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAU80X90 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.
Pushes heavy packages at 30-800mm/s on packaging lines, utilizing the 2513N thrust to redirect loaded pallets without bouncing.
Halts inbound pallets at a workstation using the compact profile body, saving space while providing firm 128kg vertical-equivalent resistance.
Ejects formed metal parts from a press bed, where the 28mm adjustable cushions absorb kinetic energy smoothly at the 90mm stroke end.
To replace the SU80X90, order the SAU80X90, confirming the 3/8" port, PT/G/NPT thread choice, and SC-series mounting hardware. This non-magnetic SKU cannot take a switch; if sensing is needed, order the SAU80X90S and note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. For load holding, know that a plain cylinder drifts on air loss—the 28mm cushions only decelerate—so add an external rod lock or pilot-operated check valve for suspended loads. If downsizing, a 63mm bore yields 1559N push at 0.5MPa; if upsizing, a 100mm bore yields 3927N. The SAUF valve-integrated option can simplify cycle control.
Replacement checklist
Yes, the AirTAC SU80X90 is discontinued. The direct replacement is the SAU80X90, which matches the 80mm bore, 90mm stroke, 2513N force, 3/8" port, and SC-series mounting. The body dimensions are unchanged.
It pushes 2513N and pulls 2268N at 0.5MPa, pushes 3518N at 0.7MPa, and reaches a 513kgf maximum at 1.0MPa. It cannot hold a load without live air—the cushions only decelerate—so use a rod lock for vertical holding. This SKU has no magnet and cannot take a sensor.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU80X90 replacement — usually within 7-8 hours.
