This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X90S, 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 SU80X90S 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 SAU80X90S, which matches its bore, stroke, force and mounting.
The AirTAC SU80X90S is a discontinued double-acting profile cylinder with an 80mm bore and 90mm stroke. Delivering 2513N push and 2268N pull at 0.5MPa, its direct replacement is the SAU80X90S, matching the 3/8" port, M20x1.5 rod thread and SC-series mounting.
Because this SU variant includes a magnet (-S), it originally used legacy CS1-B/DS1-B switches, whereas the SAU successor upgrades to CMSG/DMSG/EMSG sensors. The extruded aluminium profile is more compact than an ISO 15552 equivalent.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X90S 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 SAU80X90S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 80 | Bore size in mm. |
| ×90 | 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 heavy stamped parts from a press bed, utilizing the 2513N push force at 0.5MPa to reliably clear metal components.
Acts as a robust stopping mechanism on conveyor lines for loaded pallets, handling the kinetic impact with adjustable 28mm end cushions.
To replace this discontinued SU80X90S, order the SAU80X90S direct equivalent, verifying the 80mm bore, 90mm stroke, 3/8" port, and SC-series mounting hardware. If downsizing, the 63mm bore yields 1559N push at 0.5MPa; if upsizing, the 100mm bore provides 3927N. Note the -S magnet on this legacy model required CS1-B/DS1-B switches, but the SAU replacement uses CMSG/DMSG/EMSG sensors. For load holding, remember a standard cylinder drifts without live air—the 28mm cushions only decelerate—so add an external rod lock or pilot-operated check valve if needed. The SAU family also offers a SAUF variant with a built-in 4M solenoid valve, a feature the SU line lacked.
Replacement checklist
Yes, the SU80X90S is discontinued. The direct replacement is the AirTAC SAU80X90S. It offers identical 80mm bore, 90mm stroke, 513kgf max force, 3/8" port, and SC-series mounting compatibility.
The cylinder provides 2513N push and 2268N pull at 0.5MPa, 3518N at 0.7MPa, and a 513kgf maximum at 1.0MPa. Because your SU model has a magnet (-S), note that the legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG sensors on the SAU version.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU80X90S replacement — usually within 7-8 hours.
