This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X300SCA, 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 SU63-100 Standard Cylinder SU80X300SCA is a double-acting profile-type standard cylinder with a Ø80mm bore and 300mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X300SCA, which matches its bore, stroke, force and mounting.
The AirTAC SU80X300SCA is a discontinued double-acting profile cylinder with an 80mm bore and 300mm stroke. The direct replacement is the SAU80X300SCA, matching the 3/8" port, M20x1.5 rod thread, output force, and SC-series CA mounting.
Because the SU is end-of-life, buyers should migrate to the SAU family. The SAU body retains the compact extruded aluminum profile—shorter than a same-bore ISO 15552 unit—while upgrading the sensor groove to accept current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B reed sensors used here. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve, a self-switching option the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X300SCA 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 SAU80X300SCA produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 80 | Bore size in mm. |
| ×300 | 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.
Leverages the 2513N push force at 0.5MPa to push heavy pallets onto adjacent conveyor lines, utilizing the 300mm stroke to clear the transport lane completely.
Handles vertical lifting of dense corrugated cartons up to 128kg, taking advantage of the compact 80mm profile body to fit within tight packaging machine frames.
Ejects formed metal or plastic parts from press beds, using the CA mount for secure pivoting and the adjustable 28mm cushions to absorb high kinetic energy at stroke ends.
To replace this discontinued SU80X300SCA, order the SAU80X300SCA. Confirm the 80mm bore, 300mm stroke, 3/8" port (PT thread), M20x1.5 rod thread, and the CA clevis mount interface. Because this SKU includes the -S magnet, note that your old CS1-B/DS1-B switches will not fit the SAU groove; you must upgrade to CMSG/DMSG/EMSG sensors. Sizing both ways: a 63mm bore gives 1559N push at 0.5MPa, while a 100mm bore gives 3927N—choose based on your actual load. For the 300mm stroke, add external guides to prevent rod bending under side loads. A plain cylinder drifts on air loss; the 28mm adjustable cushion only decelerates near stroke end, so use an external rod lock or pilot-operated check valve for held loads. If you need integrated air control, explore the SAUF valve-cylinder variant.
Replacement checklist
Yes, the AirTAC SU80X300SCA is discontinued. The direct replacement is the SAU80X300SCA. It matches the 80mm bore, 300mm stroke, 3/8" port, output force, and SC-series CA mounting. You can swap it directly without altering your mechanical footprint.
At 0.5MPa it provides 2513N push and 2268N pull; at 0.7MPa push is 3518N, and the theoretical max is 513kgf at 1.0MPa. This -S model has a piston magnet for legacy CS1-B/DS1-B switches; when upgrading to the SAU replacement, you must switch to current CMSG/DMSG/EMSG sensors.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU80X300SCA replacement — usually within 7-8 hours.
