This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X65S, 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 SU63X65S is a double-acting profile-type standard cylinder with a Ø63mm bore and 65mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X65S, which matches its bore, stroke, force and mounting.
The AirTAC SU63X65S is a discontinued double-acting profile-type cylinder with a 63mm bore and 65mm stroke. It delivers 1559N push and 1402N pull at 0.5MPa via a 3/8" port. AirTAC replaced this legacy unit with the SAU63X65S, a direct upgrade retaining the exact body, force, and SC-series mounting.
The SAU replacement modernizes the sensor groove to accept current CMSG/DMSG/EMSG switches, whereas this -S SKU used legacy CS1-B/DS1-B reed switches. The SAU line also introduces the SAUF built-in-valve variant the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X65S 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 SAU63X65S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 63 | Bore size in mm. |
| ×65 | 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.
Applies the 1559N push force at 0.5MPa for seating bearings, stamping light sheet metal, or clinching components on an assembly line.
Uses the 65mm stroke to actuate routing gates or pusher arms, redirecting medium-weight cartons between conveyor belts.
To replace this SU63X65S, order the SAU63X65S direct equivalent, verifying the 65mm stroke, M16x1.5 rod thread, and 3/8" port. Because your model has the -S magnet, note the mandatory sensor family change: legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG on the SAU. If your application needs higher force, the 80mm bore offers 2513N push at 0.5MPa; if less is required, the 50mm bore provides 982N. A plain cylinder drifts on air loss—the cushion only decelerates—so fit an external rod lock or pilot-operated check valve for secure load holding. For automated cycling, consider the SAUF variant with its integrated 4M solenoid valve.
Replacement checklist
Yes, the AirTAC SU63X65S is discontinued. The direct replacement is the SAU63X65S. It shares the same 63mm bore, 65mm stroke, 3/8" port, output force, and SC-series mounting, so it drops directly into the same application.
The 63mm bore delivers 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, and a 318kgf maximum at 1.0MPa. Because this is an -S model with a magnet, it originally used CS1-B/DS1-B switches; the SAU replacement requires the newer CMSG/DMSG/EMSG sensor family.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU63X65S replacement — usually within 7-8 hours.
