This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X265, 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.
Airtac SU63-100 Standard Cylinder SU63X265
The AirTAC Airtac SU63-100 Standard Cylinder SU63X265 is a double-acting profile-type standard cylinder with a Ø63mm bore and 265mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X265, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X265
The AirTAC SU63X265 is a discontinued double-acting profile-type cylinder with a 63mm bore and 265mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 unit of the same bore while delivering 1559N push and 1402N pull at 0.5MPa. AirTAC replaced this EOL model with the SAU63X265, a direct replacement retaining the exact 3/8" port, M16x1.5 rod thread, and SC-series mounting.
Because this SKU lacks a magnet, it cannot accept a position switch. The SAU upgrade also introduces the SAUF variant with a built-in 4M solenoid valve, which the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X265 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAU63X265 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

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.
Where the Airtac SU63-100 Standard Cylinder SU63X265 Is Used
Package Diverting
Actuates diverting arms on packaging lines, using the 1559N push force at 0.5MPa to reliably push 79kg vertical-equivalent loads across the 265mm stroke.
Pallet Stopping
Deploys as a pneumatic stop gate in low-profile material handling conveyors, benefiting from the compact extruded barrel to save space in tight transfer zones.
Clamp Actuation
Drives mid-stroke clamping mechanisms on machining fixtures where the 1402N pull force securely holds workpieces without requiring full extension.
Replacing the Airtac SU63-100 Standard Cylinder SU63X265 with the SAU63X265
To replace the SU63X265, order the SAU63X265 and verify your 3/8" port threads (PT, G, or NPT) and SC-series mounting hardware. If you need position sensing, you must move to an -S version of the SAU and upgrade from the legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG family. At 265mm stroke, ensure adequate guidance to prevent rod bending and side-load wear. For higher force needs, step up to the 80mm bore (2513N push @0.5MPa); for lighter loads, drop to the 50mm bore (982N push @0.5MPa). Remember that a standard cylinder drifts without live air—the cushion only decelerates at stroke end—so install an external rod lock or pilot-operated check valve for load holding. The SAUF valve-integrated option can also simplify cycling.
Replacement checklist
- ✓ Same bore / stroke → SAU63X265
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SU63-100 Standard Cylinder SU63X265 FAQ
Yes, the SU63X265 is discontinued. The direct replacement is the AirTAC SAU63X265. It shares the identical 63mm bore, 265mm stroke, 3/8" port, output force, and SC-series mounting, so it fits the same application directly. The SAU body also offers the new SAUF built-in-valve option.
At 0.5MPa it provides 1559N push and 1402N pull; 2182N push at 0.7MPa; 2805N at 0.9MPa; and a theoretical max of 318kgf at 1.0MPa. This specific non-magnetic SKU cannot take a sensor. If you need sensing on the SAU replacement, you must use an -S model with current CMSG/DMSG/EMSG switches.
