This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X260S, 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 SU63X260S
The AirTAC Airtac SU63-100 Standard Cylinder SU63X260S is a double-acting profile-type standard cylinder with a Ø63mm bore and 260mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X260S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X260S
The AirTAC SU63X260S is a discontinued double-acting profile cylinder with a 63 mm bore and 260 mm stroke. Built with an extruded aluminium barrel, it is more compact than an ISO 15552 cylinder of the same size while sharing AirTAC SC-series mounting accessories.
Because this SU model is end-of-life, you should order the direct replacement SAU63X260S. It matches the exact bore, stroke, 3/8" port, M16x1.5 rod thread and output force. The SAU upgrade introduces current CMSG/DMSG/EMSG sensors to replace the legacy CS1-B/DS1-B switches used on this -S SKU, and it offers a new SAUF variant with a built-in 4M solenoid valve that the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X260S 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 SAU63X260S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 63 | Bore size in mm. |
| ×260 | 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.
Where the Airtac SU63-100 Standard Cylinder SU63X260S Is Used
Package Diverting
Actuates diverting arms on packaging lines, using the 260 mm stroke to push cartons cleanly between adjacent belts at 30-800 mm/s.
Pallet Stopping
Serves as a pneumatic stop gate for roller conveyors, securely halting loaded pallets up to 79 kg using the 0.5 MPa vertical lift margin.
Clamp Actuation
Drives mid-force clamping fixtures on machining cells, where the compact profile body saves space while delivering 2182 N at 0.7 MPa.
Replacing the Airtac SU63-100 Standard Cylinder SU63X260S with the SAU63X260S
To replace the SU63X260S, order the SAU63X260S and verify your 3/8" port, M16x1.5 rod thread and SC-series mounting hardware. Because this SKU includes a magnet (-S), you must upgrade your position sensing from the old CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG family. If your application requires load holding on air loss, note that the adjustable 21 mm cushions only decelerate the piston at stroke end; you must add an external rod lock or pilot-operated check valve. At 260 mm stroke, side-load and rod-bending forces are moderate, but ensure proper guide alignment to prevent seal wear. If you need higher force, the neighbouring 80 mm bore provides 2513 N push at 0.5 MPa; if you need less, the 50 mm bore offers 982 N. For automated self-switching without external plumbing, consider the SAUF valve-integrated option.
Replacement checklist
- ✓ Same bore / stroke → SAU63X260S
- ✓ 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 SU63X260S FAQ
Yes, the SU63X260S is discontinued. The direct replacement is the AirTAC SAU63X260S. It provides identical 63 mm bore, 260 mm stroke, 3/8" port, M16x1.5 rod thread, output force and SC-series mounting compatibility, so it fits the same application directly.
At 0.5 MPa it provides 1559 N push and 1402 N pull force, rising to 2182 N push at 0.7 MPa and a theoretical maximum of 318 kgf at 1.0 MPa. Because this is an -S model with a piston magnet, it originally used legacy CS1-B/DS1-B switches; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
