This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X580S, 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 SU63X580S is a double-acting profile-type standard cylinder with a Ø63mm bore and 580mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X580S, which matches its bore, stroke, force and mounting.
The AirTAC SU63X580S is a discontinued double-acting profile-type cylinder with a 63mm bore and 580mm stroke. It delivers 1559N push and 1402N pull at 0.5MPa, using a 20mm rod and 3/8" port. AirTAC replaced this legacy unit with the SAU63X580S, a direct upgrade retaining the exact bore, stroke, force, port size and SC-series mounting.
The SAU replacement upgrades the -S magnet sensor family from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches, and introduces the SAUF built-in 4M valve option the SU line lacked. Note that standard cylinders drift without live air; the cushions only decelerate, so use an external rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X580S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAU63X580S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 63 | Bore size in mm. |
| ×580 | 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.
Pushes packages across transfer lanes using the full 580mm travel, relying on the 1559N thrust at 0.5MPa to overcome guide friction.
Ejects formed parts from machinery beds, using adjustable 21mm cushions to decelerate the payload smoothly at stroke end.
To replace the SU63X580S, order the SAU63X580S direct equivalent, verifying your 3/8" port, M16x1.5 rod thread, PT/G/NPT thread standard, and SC-series mounting (LB/FA/FB/CA/CB). Because this SKU includes -S, you must upgrade your sensors from CS1-B/DS1-B to CMSG/DMSG/EMSG. For load holding, add an external rod lock or pilot-operated check valve, as cushions only decelerate. With a 580mm stroke, prevent rod bending by guiding the load externally to avoid side loads. If downsizing, a 50mm bore yields 982N push at 0.5MPa; if upsizing, an 80mm bore provides 2513N. The SAUF variant adds a built-in valve if you need self-switching.
Replacement checklist
Yes, the SU63X580S is discontinued. The direct replacement is the AirTAC SAU63X580S. It shares the identical 63mm bore, 580mm stroke, output force, 3/8" port and SC-series mounting, so it drops straight into the same application.
The 63mm bore provides 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, and a 318kgf theoretical max at 1.0MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches must be replaced with CMSG/DMSG/EMSG sensors on the new SAU unit.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU63X580S replacement — usually within 7-8 hours.
