This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X65, 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 SU63X65 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 SAU63X65, which matches its bore, stroke, force and mounting.
The AirTAC SU63X65 is a discontinued double-acting profile-type cylinder with a 63mm bore and 65mm stroke. It delivers 1559N push force at 0.5MPa via a 3/8" port. AirTAC replaced this unit with the SAU63X65, a direct alternative retaining the exact bore, stroke, output force, port size and SC-series mounting footprint.
Because this is a non-magnet SKU, it cannot accept position sensors. If sensing is needed, the SAU upgrade uses modern CMSG/DMSG/EMSG switches. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X65 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 SAU63X65 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.
Actuates routing gates on packaging lines, using the 1559N force to push standard cartons reliably at cycle speeds up to 800mm/s.
Functions as a pneumatic stop in low-profile conveyor modules, where the compact extruded body saves space compared to standard ISO cylinders.
Drives mid-force clamping mechanisms in machining fixtures, providing firm holding via a 20mm piston rod for workpiece stability.
To replace this discontinued SU63X65, order the SAU63X65. Verify your 3/8" port thread (PT, G or NPT), M16x1.5 rod end, and SC-series mounting hardware (LB, FA, FB, CA, CB, TC). Since this specific SKU lacks a magnet, it cannot hold a sensor; if you require position detection, the SAU replacement requires CMSG/DMSG/EMSG switches. A plain cylinder drifts on air loss, so use an external rod lock or pilot-operated check valve for load holding. If downsizing, a 50mm bore yields 982N push at 0.5MPa; if upsizing, an 80mm bore provides 2513N. At 65mm stroke, side-load risks are minimal, but always guide the load.
Replacement checklist
Yes, the SU63X65 is discontinued. The direct replacement is the AirTAC SAU63X65. It features the same 63mm bore, 65mm stroke, 1559N force, 3/8" port, and SC-series mounting accessories, so it fits the same application directly.
At 0.5MPa it provides 1559N push and 1402N pull; 2182N push at 0.7MPa; 2805N at 0.9MPa; and a max of 318kgf at 1.0MPa. This non-magnet SKU cannot take a sensor. If you need sensing, the SAU replacement uses CMSG/DMSG/EMSG switches.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU63X65 replacement — usually within 7-8 hours.
