This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X1200S, 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 SU63X1200S
The AirTAC SU63-100 Standard Cylinder SU63X1200S is a double-acting profile-type standard cylinder with a Ø63mm bore and 1200mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X1200S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X1200S
The AirTAC SU63X1200S is a discontinued double-acting profile-type cylinder with a 63 mm bore and 1200 mm stroke. It delivers 1559 N push force at 0.5 MPa via a 3/8 inch port. The direct replacement is the SAU63X1200S, matching the bore, stroke, output force, and SC-series mounting.
Because this is a compact extruded aluminum profile body, it is shorter than an ISO 15552 unit of the same size. The -S magnet on this legacy model worked with CS1-B/DS1-B switches, whereas the SAU replacement uses current CMSG/DMSG/EMSG sensors and offers a new SAUF built-in valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X1200S 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 SAU63X1200S 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 SU63X1200S Is Used
Long-Stroke Diversion
Pushes heavy pallets sideways on a 1200 mm lane using the 1559 N push force at 0.5 MPa, requiring external guides to support the extended rod.
Large Door Actuation
Opens 1.2 meter machine safety doors, utilizing the adjustable 21 mm air cushions at both ends to decelerate the 63 mm piston smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU63X1200S with the SAU63X1200S
To replace the SU63X1200S, order the SAU63X1200S. Verify your 3/8 inch port, M16x1.5 rod thread, and SC-series mounting hardware, as these remain identical. If downsizing, a 50 mm bore gives 982 N push at 0.5 MPa; if upsizing, an 80 mm bore yields 2513 N. The 1200 mm stroke demands external guide rails to prevent rod bending under side loads. Note the -S magnet requires changing your legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. Air cushions only decelerate the piston; use an external rod lock or pilot-operated check valve to hold loads securely.
Replacement checklist
- ✓ Same bore / stroke → SAU63X1200S
- ✓ 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 SU63X1200S FAQ
Yes, the SU63X1200S is discontinued. The direct replacement is the SAU63X1200S. It provides identical bore, stroke, force, 3/8 inch port, and SC-series mounting compatibility. You simply order the SAU model for a direct physical swap.
The 63 mm bore provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a maximum theoretical force of 318 kgf at 1.0 MPa. Because this is an -S magnet model, you must upgrade from the legacy CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG sensor family when installing the SAU replacement.
