This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X280S, 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 SU63X280S
The AirTAC Airtac SU63-100 Standard Cylinder SU63X280S is a double-acting profile-type standard cylinder with a Ø63mm bore and 280mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X280S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X280S
The AirTAC SU63X280S is a discontinued double-acting profile cylinder with a 63mm bore and 280mm stroke. It delivers 1559N push and 1402N pull at 0.5MPa. The direct replacement is the SAU63X280S, matching the 3/8" port, M16x1.5 rod thread, output force, and SC-series mounting.
The SAU upgrade switches the -S magnet from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors, and introduces the SAUF built-in-valve variant the SU lacked. The extruded aluminium profile is shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X280S 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 SAU63X280S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -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 SU63X280S Is Used
Package Diverting
Actuates diverting arms on packaging lines, using the 280mm stroke to push cartons cleanly between adjacent conveyor belts.
Pallet Stopper Gate
Raises and lowers stop gates at palletizing stations, where the 1559N thrust at 0.5MPa securely halts incoming pallets.
Component Ejection
Ejects machined parts from CNC fixtures, taking advantage of the compact profile body to fit tight machine envelopes.
Replacing the Airtac SU63-100 Standard Cylinder SU63X280S with the SAU63X280S
To replace this SU63X280S, order the SAU63X280S and confirm the 3/8" port, PT/G/NPT thread choice, and SC-series mounting hardware (LB/FA/FB/CA/CB). Because this SKU includes the -S magnet, you must upgrade your switches from CS1-B/DS1-B to CMSG/DMSG/EMSG. Sizing both ways: dropping to a 50mm bore yields 982N push at 0.5MPa, while stepping up to an 80mm bore provides 2513N. At 280mm stroke, guide the load to prevent rod bending and side-load wear. A plain cylinder drifts on air loss—the cushion only decelerates—so fit an external rod lock for held loads. If self-switching is needed, the SAUF variant integrates a 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU63X280S
- ✓ 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 SU63X280S FAQ
Yes, the SU63X280S is discontinued. The direct replacement is the SAU63X280S. It matches the 63mm bore, 280mm stroke, 3/8" port, output force, and SC-series mounting accessories. You can swap it directly without altering your mechanical setup.
At 0.5MPa it provides 1559N push and 1402N pull, 2182N push at 0.7MPa, and a 318kgf maximum at 1.0MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches are obsolete; the SAU63X280S replacement requires current CMSG/DMSG/EMSG sensors.
